An acute diarrheal disease endemic in India and Southeast Asia whose causative agent is VIBRIO CHOLERAE. This condition can lead to severe dehydration in a matter of hours unless quickly treated.
An ENTEROTOXIN from VIBRIO CHOLERAE. It consists of two major protomers, the heavy (H) or A subunit and the B protomer which consists of 5 light (L) or B subunits. The catalytic A subunit is proteolytically cleaved into fragments A1 and A2. The A1 fragment is a MONO(ADP-RIBOSE) TRANSFERASE. The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment. The A1 catalyzed transfer of ADP-RIBOSE to the alpha subunits of heterotrimeric G PROTEINS activates the production of CYCLIC AMP. Increased levels of cyclic AMP are thought to modulate release of fluid and electrolytes from intestinal crypt cells.

Environmental signals modulate ToxT-dependent virulence factor expression in Vibrio cholerae. (1/1261)

The regulatory protein ToxT directly activates the transcription of virulence factors in Vibrio cholerae, including cholera toxin (CT) and the toxin-coregulated pilus (TCP). Specific environmental signals stimulate virulence factor expression by inducing the transcription of toxT. We demonstrate that transcriptional activation by the ToxT protein is also modulated by environmental signals. ToxT expressed from an inducible promoter activated high-level expression of CT and TCP in V. cholerae at 30 degrees C, but expression of CT and TCP was significantly decreased or abolished by the addition of 0.4% bile to the medium and/or an increase of the temperature to 37 degrees C. Also, expression of six ToxT-dependent TnphoA fusions was modulated by temperature and bile. Measurement of ToxT-dependent transcription of genes encoding CT and TCP by ctxAp- and tcpAp-luciferase fusions confirmed that negative regulation by 37 degrees C or bile occurs at the transcriptional level in V. cholerae. Interestingly, ToxT-dependent transcription of these same promoters in Salmonella typhimurium was relatively insensitive to regulation by temperature or bile. These data are consistent with ToxT transcriptional activity being modulated by environmental signals in V. cholerae and demonstrate an additional level of complexity governing the expression of virulence factors in this pathogen. We propose that negative regulation of ToxT-dependent transcription by environmental signals prevents the incorrect temporal and spatial expression of virulence factors during cholera pathogenesis.  (+info)

Transmission of epidemic Vibrio cholerae O1 in rural western Kenya associated with drinking water from Lake Victoria: an environmental reservoir for cholera? (2/1261)

Sub-Saharan Africa has the highest reported cholera incidence and mortality rates in the world. In 1997, a cholera epidemic occurred in western Kenya. Between June 1997 and March 1998, 14,275 cholera admissions to hospitals in Nyanza Province in western Kenya were reported. There were 547 deaths (case fatality rate = 4%). Of 31 Vibrio cholerae O1 isolates tested, all but one were sensitive to tetracycline. We performed a case-control study among 61 cholera patients and age-, sex-, and clinic-matched controls. Multivariate analysis showed that risk factors for cholera were drinking water from Lake Victoria or from a stream, sharing food with a person with watery diarrhea, and attending funeral feasts. Compared with other diarrheal pathogens, cholera was more common among persons living in a village bordering Lake Victoria. Cholera has become an important public health concern in western Kenya, and may become an endemic pathogen in the region.  (+info)

Effects of changes in membrane sodium flux on virulence gene expression in Vibrio cholerae. (3/1261)

The expression of several virulence factors of Vibrio cholerae is coordinately regulated by the ToxT molecule and the membrane proteins TcpP/H and ToxR/S, which are required for toxT transcription. To identify proteins that negatively affect toxT transcription, we screened transposon mutants of V. cholerae carrying a chromosomally integrated toxT::lacZ reporter construct for darker blue colonies on media containing 5-bromo-4-chlor-3-indolyl beta-D galactoside (X-gal). Two mutants had transposon insertions in a region homologous to the nqr gene cluster of Vibrio alginolyticus, encoding a sodium-translocating NADH-ubiquinone oxidoreductase (NQR). In V. alginolyticus, NQR is a respiration-linked Na+ extrusion pump generating a sodium motive force that can be used for solute import, ATP synthesis, and flagella rotation. Inhibition of NQR enzyme function in V. cholerae by the specific inhibitor 2-n-heptyl-4-hydroxyquinoline N-oxide (HQNO) resulted in elevated toxT::lacZ activity. Increased toxT::lacZ expression in an nqr mutant strain compared with the parental strain was observed when the TcpP/H molecules alone were strongly expressed, suggesting that the negative effect of the NQR complex on toxT transcription is mediated through TcpP/H. However, the ability of the TcpP/H proteins to activate the toxT::lacZ reporter construct was greatly diminished in the presence of high NaCl concentrations in the growth medium. The flagellar motor of V. cholerae appears to be driven by a sodium motive force, and modulation of flagella rotation by inhibitory drugs, high media viscosity, or specific mutations resulted in increases of toxT::lacZ expression. Thus, the regulation of the main virulence factors of V. cholerae appears to be modulated by endogenous and exogenous sodium levels in a complex way.  (+info)

How intestinal bacteria cause disease. (4/1261)

An improved understanding of how intestinal bacteria cause disease has become increasingly important because of the emergence of new enteric pathogens, increasing threats of drug resistance, and a growing awareness of their importance in malnutrition and diarrhea. Reviewed here are the varied ways that intestinal bacteria cause disease, which provide fundamental lessons about microbial pathogenesis as well as cell signaling. Following colonization, enteric pathogens may adhere to or invade the epithelium or may produce secretory exotoxins or cytotoxins. In addition, by direct or indirect effects, they may trigger secondary mediator release of cytokines that attract inflammatory cells, which release further products, such as prostaglandins or platelet-activating factor, which can also trigger secretion. An improved understanding of pathogenesis not only opens new approaches to treatment and control but may also suggest improved simple means of diagnosis and even vaccine development.  (+info)

Expanded safety and immunogenicity of a bivalent, oral, attenuated cholera vaccine, CVD 103-HgR plus CVD 111, in United States military personnel stationed in Panama. (5/1261)

To provide optimum protection against classical and El Tor biotypes of Vibrio cholerae O1, a single-dose, oral cholera vaccine was developed by combining two live, attenuated vaccine strains, CVD 103-HgR (classical, Inaba) and CVD 111 (El Tor, Ogawa). The vaccines were formulated in a double-chamber sachet; one chamber contained lyophilized bacteria, and the other contained buffer. A total of 170 partially-immune American soldiers stationed in Panama received one of the following five formulations: (a) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(7) CFU, (b) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(6) CFU, (c) CVD 103-HgR alone at 10(8) CFU, (d) CVD 111 alone at 10(7) CFU, or (e) inactivated Escherichia coli placebo. Among those who received CVD 111 at the high or low dose either alone or in combination with CVD 103-HgR, 8 of 103 had diarrhea, defined as three or more liquid stools. None of the 32 volunteers who received CVD 103-HgR alone or the 35 placebo recipients had diarrhea. CVD 111 was detected in the stools of 46% of the 103 volunteers who received it. About 65% of all persons who received CVD 103-HgR either alone or in combination had a fourfold rise in Inaba vibriocidal titers. The postvaccination geometric mean titers were comparable among groups, ranging from 450 to 550. Ogawa vibriocidal titers were about twice as high in persons who received CVD 111 as in those who received CVD 103-HgR alone (600 versus 300). The addition of CVD 111 improved the overall seroconversion rate and doubled the serum Ogawa vibriocidal titers, suggesting that the combination of an El Tor and a classical cholera strain is desirable. While CVD 111 was previously found to be well tolerated in semiimmune Peruvians, the adverse effects observed in this study indicate that this strain requires further attenuation before it can be safely used in nonimmune populations.  (+info)

A reassessment of the cost-effectiveness of water and sanitation interventions in programmes for controlling childhood diarrhoea. (6/1261)

Cost-effectiveness analysis indicates that some water supply and sanitation (WSS) interventions are highly cost-effective for the control of diarrhoea among under-5-year-olds, on a par with oral rehydration therapy. These are relatively inexpensive "software-related" interventions such as hygiene education, social marketing of good hygiene practices, regulation of drinking-water, and monitoring of water quality. Such interventions are needed to ensure that the potentially positive health impacts of WSS infrastructure are fully realized in practice. The perception that WSS programmes are not a cost-effective use of health sector resources has arisen from three factors: an assumption that all WSS interventions involve construction of physical infrastructure, a misperception of the health sector's role in WSS programmes, and a misunderstanding of the scope of cost-effectiveness analysis. WSS infrastructure ("hardware") is generally built and operated by public works agencies and financed by construction grants, operational subsidies, user fees and property taxes. Health sector agencies should provide "software" such as project design, hygiene education, and water quality regulation. Cost-effectiveness analysis should measure the incremental health impacts attributable to health sector investments, using the actual call on health sector resources as the measure of cost. The cost-effectiveness of a set of hardware and software combinations is estimated, using US$ per case averted, US$ per death averted, and US$ per disability-adjusted life year (DALY) saved.  (+info)

Molecular characterization of a new ribotype of Vibrio cholerae O139 Bengal associated with an outbreak of cholera in Bangladesh. (7/1261)

Vibrio cholerae O139 Bengal initially appeared in the southern coastal region of Bangladesh and spread northward, causing explosive epidemics during 1992 and 1993. The resurgence of V. cholerae O139 during 1995 after its transient displacement by a new clone of El Tor vibrios demonstrated rapid changes in the epidemiology of cholera in Bangladesh. A recent outbreak of cholera in two north-central districts of Bangladesh caused by V. cholerae O139 led us to analyze strains collected from the outbreak and compare them with V. cholerae O139 strains isolated from other regions of Bangladesh and neighboring India to investigate their origins. Analysis of restriction fragment length polymorphisms in genes for conserved rRNA (ribotype) revealed that the recently isolated V. cholerae O139 strains belonged to a new ribotype which was distinct from previously described ribotypes of toxigenic V. cholerae O139. All strains carried the genes for toxin-coregulated pili (tcpA and tcpI) and accessory colonization factor (acfB), the regulatory gene toxR, and multiple copies of the lysogenic phage genome encoding cholera toxin (CTXPhi) and belonged to a previously described ctxA genotype. Comparative analysis of the rfb gene cluster by PCR revealed the absence of a large region of the O1-specific rfb operon downstream of the rfaD gene and the presence of an O139-specific genomic region in all O139 strains. Southern hybridization analysis of the O139-specific genomic region also produced identical restriction patterns in strains belonging to the new ribotype and those of previously described ribotypes. These results suggested that the new ribotype of Bengal vibrios possibly originated from an existing strain of V. cholerae O139 by genetic changes in the rRNA operons. In contrast to previously isolated O139 strains which mostly had resistance to trimethoprim, sulfamethoxazole, and streptomycin encoded by a transposon (SXT element), 68.6% of the toxigenic strains analyzed in the present study, including all strains belonging to the new ribotype, were susceptible to these antibiotics. Molecular analysis of the SXT element revealed possible deletion of a 3.6-kb region of the SXT element in strains which were susceptible to the antibiotics. Thus, V. cholerae O139 strains in Bangladesh are also undergoing considerable reassortments in genetic elements encoding antimicrobial resistance.  (+info)

Cholera in the 1990s. (8/1261)

Two strains of Vibrio cholerae are currently significant in cholera: a remnant from the sixth pandemic (1899-1923) still present in South Asia and the seventh pandemic strain which emerged in 1961. The 1990s were marked by spread of the seventh pandemic to South America in 1991 and appearance of an O139 form of the seventh pandemic strain in 1992 (or possibly 1991), which in 1993 predominated in some areas but then declined. Molecular analysis showed that the sixth and the seventh pandemic clones are related, but have a different TCP pathogenicity island and possibly different CTX phages, suggesting independent derivation from related environmental strains. Upsurges of the seventh pandemic were accompanied by increased genetic variation enabling the relationships between strains to be studied, but the basis for variation in pathogenicity is not known. There is clearly a risk of new forms arising and a strategy for speedy development of vaccines needs to be established.  (+info)

Here, we have shown that cross-sectional antibody profiles can be used to identify individuals recently infected with V. cholerae O1 with high sensitivity and specificity both in the hyperendemic Bangladeshi population used to train the model and in a separate population of cholera-naïve individuals from North America. We confirmed the importance of vibriocidal antibodies as a marker for recent infection and showed that the addition of other serologic markers provided greater resolution to reliably identify recent infections. These results provide a pathway for new approaches to assessing the burden of cholera across different populations, potentially overcoming many of the shortcomings of traditional clinic- and microbiology-based surveillance systems.. Measures of cholera incidence from serosurveys could help create more robust cholera surveillance systems, thereby improving our understanding of cholera epidemiology and providing new tools to track progress in the global fight against ...
The Bill and Melinda Gates Foundation has awarded Professor James J. Collins (BME, MSE, SE) a Grand Challenges Explorations grant to encourage his labs pursuit of a novel approach to cholera prevention.. In their proposed project, Collins and two postdoctoral fellows in his lab, Ewen Cameron and Peter Belenky, seek to use synthetic biology techniques to engineer a probiotic yogurt bacterium, Lactobacillus gasseri, to detect and kill the cholera bacterium, Vibrio cholerae, in the human intestine. The probiotic could be supplied as an inexpensive, freeze-dried powder to endemic populations to prevent cholera, an acute, food or water-borne diarrheal infection leading to more than 100,000 deaths each year.. We are delighted to be selected for the Gates Foundation program, said Collins. This funding will enable us to explore using innovative synthetic biology approaches to detect and treat cholera infections, a major health problem facing many poor communities in the world, including those in ...
Abstract. Multiple Vibrio cholerae infections within the same household are common. Household contacts of patients with cholera were observed with daily clinical assessments and collection of rectal swab cultures for nine days after presentation of the index case. During the follow-up period, 71 (24%) of 294 household contacts developed a positive V. cholerae rectal swab, signifying bacterial shedding. The average length of bacterial shedding was 2.0 days (95% confidence interval 1.7-2.4). However, 16 (5%) of 294 contacts shed V. cholerae for ≥ 4 days. In a multivariate analysis, malnutrition was predictive of long-term shedding (odds ratio = 1.4, 95% confidence interval = 1.3-13, P = 0.02). High rates of V. cholerae infection and bacterial shedding among household contacts of cholera patients represent an opportunity for intervention to reduce V. cholerae transmission.

Cholera interannual periodicity and the link between cholera dynamics and climate variability remain incompletely understood and generally focused only on endemic regions [7, 9, 14, 15]. Pascual et al. [5] and Rodo et al. [7] described a role of El Niño/Southern Oscillation in the dynamics of cholera in Bangladesh. In addition, the complex relationship between largescale climatic variability and spatiotemporal patterns under local environmental conditions and weather contributes to the dynamics of local pathogen populations in aquatic ecosystems [34], and/or disease transmission [35, 36]. In this context, using a comparative approach developed for macroecology applications [37], the relationship between cholera incidence in five different African countries and climate interannual variability was explored. Indeed, analyses of long-term monthly disease time series underline both the complex, nonstationary dynamics of cholera epidemics in West Africa, and a relationship with large-scale climate ...
CVD 103-HgR (Vaxchora, PaxVax) cholera vaccine was approved by the Food and Drug Administration in June 2016. ACIP has not yet published recommendations for Vaxchora. However, at their June 2016 meeting, ACIP voted to recommend vaccination for adults 18 through 64 years old traveling to areas of active cholera transmission. An area of active cholera transmission is defined as a province, state, or other administrative subdivision within a country with endemic or epidemic cholera caused by toxigenic V. cholerae O1 and includes areas with cholera activity within the last 1 year that are prone to recurrence of cholera epidemics; it does not include areas where rare sporadic cases have been reported. No country or territory currently requires vaccination against cholera as a condition for entry. ...

We noticed that while the weekly reported cases seemed to be declining in the third and fourth years of the outbreak, the frequency of isolation of toxigenic V. cholerae in the environment was actually increasing. Under the current dogma of cholera transmission models, V. cholerae shed by humans into the environment only exists in a transient state governed by a constant rate of decay. The assumption is that although V. cholerae is an aquatic pathogen, it lacks the ability to replicate and survive for prolonged periods in surface waters. Given our understanding of V. cholerae biology, this is likely an oversimplification which precluded the possibility for an increase in environmental concentrations during a period where cholera incidence was infrequent or declining, ...
In January 1991, epidemic cholera appeared in Peru and quickly spread to many other Latin American countries. Because reporting of cholera cases was often delayed in some areas, the scope of the epidemic was unclear. An assessment of the conduct of surveillance for cholera in several countries identified some recurrent problems involving surveillance case definitions, laboratory surveillance, surveillance methods, national coordination, and data management. A key conclusion is that a simple, well-communicated cholera surveillance system in place during an epidemic will facilitate prevention and treatment efforts. We recommend the following measures: a) simplify case definitions for cholera; b) focus on laboratory surveillance of patients with diarrhea primarily in the initial stage of the epidemic; c) use predominantly the suspect case definition when the number of confirmed cases rises; d) transmit weekly the numbers of cases, hospitalized patients, and deaths to regional and central ...
Guidelines for Water, Sanitation and Hygiene in Cholera Treatment Centres During an outbreak of cholera, most patients can be treated in existing health facilities. However, health officials may decide
What causes cholera?. Cholera is transmitted through poor hygiene and sanitation. It is no wonder that areas of natural disasters that result in disruption of water and sanitation systems are major outbreak areas of cholera. Other hotspots for cholera outbreaks are overcrowded refugee camps where displaced human populations are temporary accommodated and urban slums. These facilities, too, have inadequate clean water and sanitation system.. Strangely enough, it is not the infection itself that usually kills cholera victims but rather the dehydration resulting from severe diarrhea and vomiting.. The Haitian capital city Port-au-Prince is a classic example of an urban area where cholera can break out.. Pandemic cholera. Like the flu, cholera has also caused pandemics in the past. WHO gives the following historical background:. ...
The Department of Health has reported a cholera outbreak in the Mpumalanga region. From 26 April to 18 May, the cumulative number of suspected and confirmed cholera cases is 174 with 3 deaths (case fatality ratio 1.7%). The outbreak has included 27 areas bordering Swaziland and Mozambique, with Tonga being the most affected area.. A team from the Department of Health, joined by a medical officer from the WHO country office, has travelled to Mpumalanga to assess the situation and make recommendations to contain the outbreak.. This is the third province after Eastern Cape and Kwazulu-Natal to report a cholera outbreak this year. From 1 January to 28 March 2003, the cumulative number of reported cholera cases in South Africa is 2362.. ...
Thirty single-nucleotide polymorphisms were used to track the spread of the seventh pandemic caused by Vibrio cholerae. Isolates from the 1991 epidemic in Latin America shared a profile with 1970s isolates from Africa, suggesting a possible origin in Africa. Data also showed that the observed genotypes spread easily and widely.
Cholera, a devastating diarrheal disease, has swept through the world in recurrent pandemics since 1817. The seventh and ongoing pandemic began in 1961 when the El Tor biotype of Vibrio cholerae O1 emerged in Indonesia. This pandemic spread through Asia and Africa and finally reached Latin America early in 1991 (1). After explosive epidemics in coastal Peru, it spread rapidly and continues throughout Latin America (Figure). Because of underreporting, the more than 1,000,000 cholera cases and 10,000 deaths reported from Latin America through 1994 (Table 1) (2) represent only a small fraction of the actual number of infections. Molecular characterization of V. cholerae O1 strains from Peru has shown that they do not match strains from anywhere else in the world; therefore, the source of the Peruvian epidemic strains remains unknown (3). Moreover, other strains have since appeared in Latin America. At least one of these, a strain resistant to multiple antimicrobial drugs, was first identified in ...
The 49th U.S.-Japan Joint Conference on Cholera and Other Bacterial Enteric Infections consisted of three days of presentations and discussions on cholera, typhoid and other diseases that affects countries like Bangladesh and Democratic Republic of Congo. The Bill and Melinda Gates Foundation-funded conference kicked off on Wednesday morning with a keynote speech from the recently inaugurated University of Florida President William Fuchs. He spoke about the Emerging Pathogens Institute and importance of great minds coming together to talk about these diseases and potential solutions.. Just eight years ago the Florida legislature created EPI as Floridas go-to research institute for new and emerging diseases. The institute has moved very quickly since then to establish research initiatives in more than 30 countries, Fuchs said. Your arrival for this annual conference reenforces that progress. Your discussions will be meaningful not only to EPI and the university-at-large, but also to the ...
Clinicians should obtain a travel history from their patients. Cholera infection is most often asymptomatic or results in mild gastroenteritis. Severe cholera is characterized by acute, profuse watery diarrhea, described as rice-water stools and often vomiting leading to volume depletion. Cholera is confirmed through culture of a stool specimen or rectal swab. Cary-Blair medium is ideal for transport, and the selective thiosulfate-citrate-bile salts agar is ideal for isolation and identification. Rehydration is the best treatment. Oral rehydration salts are used and intravenous fluids are used when necessary. For more information, see CDC Health Information for International Travel 2012.. ...

Fresh cholera outbreak has claimed no fewer than four lives and 38 others infected by the diseased in Toto Local Government Area of Nasarawa State.. A statement signed by public relations officer, state ministry of health, Musa Abdullahi and made available to The PUNCH in Lafia, said that cholera outbreak was experienced in Shege Ward in Toto LGA where 38 cases were confirmed and four died before reaching the primary healthcare facility.. According to him, some of the affected victims are currently stable and the patients are responding to treatment, stating that a team of health experts from the state ministry of health have donated drugs to the Shege community, while efforts are ongoing to contain the spread of the disease.. The state commissioner of health, Dr Daniel Iya, who was represented by state director of public health, Dr Ibrahim Adamu-Alhassan, donated the drug to the community, adding that the donation of the drug was part of the state governments intervention to avert further ...
Cholera epidemics caused by Vibrio cholerae O1 occur regularly in Bangladesh and India and sporadically in many parts of the world. In 1993, a total of 296,206 new cases of cholera were reported in South America after about a century, involving more than 15 countries. The outbreaks of cholera that have occurred during the past decade originated in coastal areas. From our previous work, V. cholerae attaches to plankton in the aquatic environment, providing the vehicle for dispersal. The organism attaches preferentially to zooplankton, particularly copepods, but it also attaches in lower numbers and without reproduction onto some species of phytoplankton. Phytoplankton provide the main food source for zooplankton so the two forms of plankton are tightly linked in space and time. Under adverse conditions of temperature and nutrients V. cholerae enters a dormant, non-culturable state which makes it difficult to detect. Although V. cholerae cannot be detected in any state by remote sensing ...
From the pandemics of the 19th century to the recent disaster in Goma, Zaire, cholera has left an indelible mark on human and medical history, and the eighth pandemic appears to have started. From the pandemics of the 19th century to the recent disaster in Goma, Zaire, cholera has left an indelible mark on human and medical history. Cholera pandemics in the 19th and 20th centuries drove the development of epidemiology as a serious science. Cholera has continued to press advances in the concepts of disease ecology, basic membrane biology, and transmembrane signaling and in the application of scientific information to treatment design. Furthermore, the lessons learned from the study of pandemic cholera are likely to provide insights into the best means of stopping other pandemics. In spite of tremendous scientific and clinical progress, however, the seventh pandemic has lasted 33 years, and the eighth pandemic appears to have started.
The world has experienced 7 cholera pandemics since 1817. The first six were caused by the classic biotype of the O1 serogroup of Vibrio cholerae. The 7th pandemic which began in 1961 and is still ongoing (with spread to Haiti and Mexico) is due to the less virulent El Tor biotype of O1 V.cholerae. In a project, my colleagues and I estimated global cholera costs as exceeding $3 billion annually. It was in 1849 during the 2nd pandemic that Dr. John Snow made his pathbreaking epidemiological discovery regarding the role of water in the spread of the cholera microbe--yet to be identified (see The Ghost Map and The Strange Case of the Broad Street Pump). During that pandemic, Dr. John Neill of Philadelphia preserved an intestine from a patient for further study.. The New England Journal of Medicine just published the results of a successful attempt to extract the cholera microbe from that over-a-century old specimen. The bacterium recovered was of the classical biotype (as predicted) and had a ...
The municipality of Plaine du Nord and Grison-Garde, La Bruyere and La Souffriere (the areas of the municipality of Acul du Nord) continue to send cholera patients to the CTC of Robillard. I do not see anything done yet to improve the situation of Robillard that is becoming chaotic. I do not want to have to experience such a stressful experience like the one of last Sunday. Cholera is an issue of public health. I do not understand the reason why the cholera patients of the CTC of Robillard are treated the way they are treated. Who has the financial means to help the cholera patients in Haiti? Can you help me know who received financial assistance to help them? Forgive my complaints, because I am tired to have to carry the burden of the cholera patients while the are people who have the responsibility to do that. I have to reapeat that the situation of Robilard is urgent. Those who have to improve that situation, what are they waiting for? Are they waiting for an human disaster to move quickly? I ...
Interdisciplinary Perspectives on Infectious Diseases is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies related to all aspects of infectious diseases.
LAST month the United Nations Independent Expert on Human Rights in Haiti delivered his annual assessment (French version here) of the state of the poorest country in the Americas. Gustavo Gallon, a respected Colombian jurist, wrote of many troubling-and familiar--problems. They included prolonged pre-trial detention for 80% of all prisoners in Haitian jails; institutional brittleness on account of long-delayed elections to the Senate and local bodies; rising homicide rates; and a depressing predilection for public lynching, which indicates little confidence in the justice system. If the indictment of Haiti was unsurprising, less predictable was Mr Gallons position on the countrys cholera epidemic, which first broke out in 2010. More than 8,000 Haitians have since died from cholera, and nearly 700,000 more, or one out of every 16 people, infected. Medical evidence indicates the cholera strain was brought to Haiti by Nepalese UN peacekeepers, although the UN neither admits responsibility for ...
A new study has found that oral vaccines could prevent up to 60 percent of cholera cases in the first two years after vaccination.
A doctor tends to a woman at Lusakas Heroes Stadium, which was converted into a temporary hospital to house mounting patient as cholera swept through the city earlier this year. (Dawood Salim, AFP). Cholera is as familiar to most Zambians as the summer holidays. Its first major outbreak occurred in 1990 and lasted until 1993. Since then, the country has registered cholera cases almost every year. The number of people affected fluctuates from a few hundred cases to thousands admitted to hospital, according to the WHO.. Globally, no one knows exactly how many people contract cholera and die each year because most cases are never reported, a 2015 study published in the journal PLOS Neglected Tropical Diseases shows. But researchers estimate the bacterium infects 2.86-million people annually of whom 95 000 will die - mostly in Sub-Saharan Africa.. Vaccines such as those being used in Zambia may be a standard part of controlling cholera outbreaks now but this wasnt the case just a few years ago. ...
Sennar and Blue Nile state witnessed a significant decline in cholera cases over the past weeks. Health authorities in both states attributed the decline to efforts to combat the disease.
BACKGROUND Cholera is an ancient disease that continues to cause epidemic and pandemic disease despite ongoing efforts to limit its spread. Mathematical models provide one means of assessing the utility of various proposed interventions. However, cholera models that have been developed to date have had limitations, suggesting that there are basic elements of cholera transmission that we still do not understand. METHODS AND FINDINGS Recent laboratory findings suggest that passage of Vibrio cholerae O1 Inaba El Tor through the gastrointestinal tract results in a short-lived, hyperinfectious state of the organism that decays in a matter of hours into a state of lower infectiousness. Incorporation of this hyperinfectious state into our disease model provides a much better fit with the observed epidemic pattern of cholera. These findings help to substantiate the clinical relevance of laboratory observations regarding the hyperinfectious state, and underscore the critical importance of human-to-human versus

The recent rise of the West Nile virus in the U.S. was a profound indicator that global patterns of infectious disease are changing. Just what is driving the shifts is difficult to identify, although climate change has long been a suspect. Now two reports published online this week by the Proceedings of the National Academy of Sciences further implicate climate variability in the dynamics of one infectious disease: cholera. Using monthly mortality data for the periods 1893 to 1940 and 1980 to 2001 in present-day Bangladesh, a team led by Xavier Rodo of the University of Barcelona compared cholera outbreaks to the occurrence of the climate phenomenon known as the El Nio Southern Oscillation (ENSO). In the more recent years, the scientists found a link between ENSO and the incidence of cholera, with ENSO accounting for more than 70 percent of the disease variation. In the historical data set, however, that link was weak or absent. What is new in this work is not showing that ENSO plays a role in ...
Scientists have figured out how to predict cholera outbreaks by looking at sea life. The idea pioneered at the University of Maryland is a rise in sea temperatures lead to the production of Phytoplankton, which are the root cause of cholera. As these phytoplankton get into the water supply, cholera pathogens are released and can lead to outbreaks. Obviously fore warned is fore armed, so this is will certainly help public health officials cope with these devastating outbreaks.. Via BBC News. ...
This 5.5 x 9 (13.97 x 13.97 cm), 64-page pamphlet written by Joel Roberts recounts the 1849 cholera epidemic in Sandusky. The last five pages of the diary list people who died in the epidemic. Cholera was a major threat in the 19th century. Due to poor sanitation and ignorance of the causes of disease, Sandusky suffered several cholera outbreaks in the 1840s and 1850s. The most devastating outbreak occurred in the summer of 1849, when 400 people died and many more fled the city in fear. The citys population before the outbreak was about 5,000; it is estimated that fewer than 1,000 remained in the city during the cholera. The 1882 History of Sandusky County reported that medical men [were] taxed to their utmost to stem the tide of disease and death. The devastation caused by cholera and other epidemics helped to inspire improvements in medical care, research, and sanitation practices such as water treatment ...
This register, kept by the staff of the Sandusky City Hospital during the 1849 cholera epidemic, records patients discharged and deceased. The register is twelve pages long and lists eighty-three names. It measures 4.6 x 7 (11.68 cm x 17.78 cm). Cholera was a major threat in the 19th century. Due to poor sanitation and ignorance of the causes of disease, Sandusky suffered several cholera outbreaks in the 1840s and 1850s.

Diarrhea is a leading cause of mortality in children under 5 years along with its long-term impact on growth and cognitive development. Despite advances in the understanding of diarrheal disorders and management strategies, globally nearly 750,000 children die annually as a consequence of diarrhea. We conducted a systematic review of the efficacy and effectiveness studies. We used a standardized abstraction and grading format and performed meta-analyses for all outcomes. The estimated effect of cholera, shigella, Enterotoxigenic Escherichia coli (ETEC) and rotavirus vaccines was determined by applying the standard Child Health Epidemiology Reference Group (CHERG) rules. A total of 24 papers were selected and analyzed for all the four vaccines. Based on the evidence, we propose a 74% mortality reduction in rotavirus specific mortality, 52% reduction in cholera incidence due to their respective vaccines. We did not find sufficient evidence and a suitable outcome to project mortality reductions for cholera

The cholera strain causing the current outbreak in Haiti is most similar to cholera strains found in South Asia, according to lab reports from the Centers for Disease Control and Prevention.. Although these results indicate that the strain is non-Haitian, cholera strains may move between different areas due to global travel and trade, Haitis Minister of Health Dr. Alex Larsen said in a statement. Therefore, we will never know the exact origin of the strain that is causing the epidemic in Haiti. This strain was transmitted by contaminated food or water or an infected person.. Global travel and trade provide opportunities for infectious diseases such as cholera to spread from one country to another, according to the CDC. In most instances, cholera does not spread widely within countries where drinking water and sewage treatment are adequate. When water and sewage treatment is inadequate, as in post-earthquake Haiti, cholera can spread rapidly.. The lab findings are not unexpected, and provide ...
Haq added that that the finding calls for a significant new set of U.N. actions and that a new response will be presented publicly within the next two months.. The comments come in response to a report by U.N. special rapporteur and New York University law professor Philip Alston. According to the Washington Post, Alston argued to Secretary General Ban-ki Moon that the United Nations botch response in Haitis cholera crisis is morally unconscionable, legally indefensible and politically self-defeating.. The human rights and international law expert added that the U.N.s years-long refusal to admit its role in causing the cholera outbreak upholds a double standard according to which the U.N. insists that member states respect human rights, while rejecting any such responsibility for itself.. While the U.N.s latest statements dont go as far as to shoulder the entire blame, they represent a significant shift from the position maintained over the past six years. Statements by the U.N. as ...
Cholera is a major health burden in low- and middle-income countries. Globally, an estimated 1.3 billion people are at risk. South Asia constitutes the largest share of this at-risk population group, including at least 66 million in Bangladesh, where over 100,000 cases are reported annually. Cholera is an infectious disease characterised by severe watery diarrhoea and vomiting. Left untreated, the rapid dehydration it causes can be deadly. In the 1960s, researchers at icddr,b and its partners developed a simple solution to combat cholera - oral rehydration therapy (ORT) - a mixture of salt, sugar, and water, ingredients readily found in most homes. It has saved nearly 50 million lives from diarrhoeal diseases. However, cholera is often misdiagnosed until the patient is in an extreme condition, when ORT is not enough to prevent death by dehydration. Thus, early detection is critical in saving lives and preventing further spread of the disease. Diagnosis for cholera needs to be quick, easy, and ...
If you develop severe, watery diarrhea and vomiting - particularly after eating raw shellfish or traveling to a country where cholera is epidemic -seek medical help immediately. Cholera is highly treatable, but because dehydration can happen quickly, its important to get cholera treatment right away.. Hydration is the mainstay of treatment for cholera. Depending on how severe the diarrhea is, treatment will consist of oral or intravenous solutions to replace lost fluids. Antibiotics, which kill the bacteria, are not part of emergency treatment for mild cases. But they can reduce the duration of diarrhea by half and also reduce the excretion of the bacteria, thus helping to prevent the spread of the disease.. ...
MASS Design Group. The first permanent facility in Port-au-Prince, the CTC provides an aggressive model for cholera treatment, while creating a healing space that promotes a dignified patient experience. Both the CTCs layout and placement of amenities optimize staff and patient flow. The design tackles unique site conditions, including the lack of reliable piped water and lack of sewer system connection, by providing off-the-grid services. The roof collects rainwater, which is stored in cisterns, chlorinated, and then used for showers and sinks. The facility also decontaminates waste on-site and is designed to achieve 99.99% removal and inactivation of Cholera vibrio and other pathogenic organisms. The façade blends the use of the most advanced technology, using parametric modeling to optimize apertures for daylighting, ventilation, and privacy, with deploying analog techniques for local fabrication. The CTC will not only establish new standards for cholera treatment, but also new standards ...
Abstract An explosive epidemic of cholera due to Vibrio cholerae, biotype El Tor, serotype Inaba, was centered on the coral atoll of Tarawa, Gilbert Islands. This outbreak was a unique experience in the South and Central Pacific region. The principal mode of spread during the peak of the outbreak was probably through contamination of the main water supply. Tarawa lagoon water and shellfish were found to be contaminated with V. cholerae and ingestion of raw fish and shellfish from the lagoon also served as a source of transmission. This outbreak raises the concern of other outbreaks of cholera occurring on remote and poorly equipped Pacific islands where the environmental circumstances are conducive to cholera spread.
It has been some time since ICC reported on the cholera epidemic that began in Haiti in 2010. Until this point, there had never been a reported case of Cholera in Haiti. The strain, thought to have come from the United Nations camp 30 minutes from Port au Prince, is still infecting those utilizing the water source. Since the time of the outbreak, it is thought to have affected 700,000 people.
Author Summary Cholera outbreaks have had catastrophic impact on societies for centuries. Despite more than half a century of advocacy for safe water, sanitation and hygiene, approximately 100,000 cholera cases and 5,000 deaths were reported in Zimbabwe between August 2008 and by July 2009. Safe and effective oral cholera vaccines have been licensed and used by affluent tourists for more than a decade to prevent cholera. We asked whether oral cholera vaccines could be used to protect high risk populations at a time of cholera. We calculated how many cholera cases could have been prevented if mass cholera vaccinations would have been implemented in reaction to past cholera outbreaks. We estimate that determined, well organized mass vaccination campaigns could have prevented 34,900 (40%) cholera cases and 1,695 deaths (40%) in Zimbabwe. In the sites with endemic cholera, Kolkata and Zanzibar, a significant number of cases could have been prevented but the impact would have been less dramatic. The barriers

N2 - Background: Decisions about the use of killed oral cholera vaccines, which confer moderate levels of direct protection to vaccinees, can depend on whether the vaccines also provide indirect (herd) protection when high levels of vaccine coverage are attained. We reanalysed data from a field trial in Bangladesh to ascertain whether there is evidence of indirect protection from killed oral cholera vaccines. Methods: We analysed the first year of surveillance data from a placebo-controlled trial of B subunit-killed whole-cell and killed whole-cell-only oral cholera vaccines in children and adult women in Bangladesh. We calculated whether there was an inverse, monotonic trend for the relation ...
I can give two: one where we responded to prevent cholera and another where oral cholera vaccine (OCV) was used to contain it. Firstly, in 2014 there was an influx of refugees from South Sudan into the Gambella region of Ethiopia. In Gambella at that time there had been no cholera reported for years, but we knew there was cholera in South Sudan. Together with MSF, WHO and the national health partner (ARRA) we were able to make a strong case for oral cholera vaccination of the refugee population and surrounding host communities. If cholera came it could be contained - we wanted to make sure we were ahead of the curve. Through some good joint advocacy with partners and donors, we were able to get it approved and the Minister of Health supported it. We implemented it, and no cholera cases were reported during that acute emergency. The second example is in Tanzania, where we had a cholera outbreak. This was an emergency in 2015 with refugees coming from Burundi, and we had a cholera outbreak around ...
In follow-up of its statement of 12 June 2017 on the outbreak of cholera epidemic in Sudan, the Darfur Relief and Documentation Centre (DRDC) once again rings the alarm bell about the growing health risks facing thousands of vulnerable communities in many parts of Sudan. The ongoing cholera epidemic dates back to August 2016, when hundreds of cases of infections with cholera bacterium Vibrio Cholerae were confirmed in the Blue Nile and Sennar States. Numerous sources including the US Embassy in Khartoum confirmed the outbreak of cholera epidemic in Sudan. According to the government records more than 18,000 cases of acute watery diarrhoea - which is the symptom of cholera - were confirmed in 16 out of Sudans 18 States, including the White Nile, Blue Nile, Khartoum, Sennar, North, South and West Kordofan, River Nile, Northern State, Gedarif, Kassala, Red Sea, Gezira and East, West, South and North Darfur States. Independent medical sources in Sudan estimate that at least 25,000 people have ...
Diversity, relatedness, and ecological interactions of toxigenic Vibrio cholerae O1 populations in two distinctive habitats, the human intestine and the aquatic environment, were analyzed. Twenty environmental isolates and 42 clinical isolates were selected for study by matching serotype, geographic location of isolation in Bangladesh, and season of isolation. Genetic profiling was done by enterobacterial repetitive intergenic consensus sequence-PCR, optimized for profiling by using the fully sequenced V. cholerae El Tor N16961 genome. Five significant clonal clusters of haplotypes were found from 57 electrophoretic types. Isolates from different areas or habitats intermingled in two of the five significant clusters. Frequencies of haplotypes differed significantly only between the environmental populations (exact test; P , 0.05). Analysis of molecular variance yielded a population genetic structure reflecting the differentiating effects of geographic area, habitat, and sampling time. Although a ...
Cholera remains a substantial contributor to public health burden in many developing countries, particularly in sub-Sahara Africa. In 2014, 190,549 cases were reported to the World Health Organization (WHO), including 55% from Africa [1]. Of the 2,231 deaths reported worldwide, 1882 (84.4%) occurred in Africa. However, the true burden of cholera is poorly known and likely underestimated, because of limitations in current national surveillance systems including under-reporting, type of case-definitions used and lack of laboratory diagnostic capacities. An estimated 2.9 million cholera cases (1.3 m-4.0 m) and 95,000 cholera deaths (21,000-143,000) occur each year [2].. Targeting cholera prevention through increased access to water, sanitation and hygiene (WASH) and oral cholera vaccines (OCV) requires accurate epidemiological data at the local level. Further, such data help international organizations to prioritize where to support the places most in need.. The African Cholera Surveillance Network ...
V. cholerae and many related Gram-negative bacteria have been shown to become nonculturable under specific experimental conditions, although the time required for these cells to become nonculturable is variable (8, 9, 19-21). In this study, V. cholerae O1 cells in all microcosms became nonculturable on TCBS agar within 10-15 days, as has been reported by other investigators (19-21). V. cholerae O1 in biofilms collected from MW and in the biofilm in clinical specimens, when suspended in autoclaved MW that had tested positive for V. cholerae O1 by both culture and DFA, became nonculturable within 15 days. Conversely, MW-RT and MW-4C microcosms inoculated with freshly grown V. cholerae O1 showed culturability on TTGA and LA for 40 and 68 days, respectively. Miller et al. (22) suggested that toxigenic V. cholerae O1 could remain culturable for longer periods at a salinity of 0.25-3.0%, a pH of 8.0, and 25°C. The temperature, pH, and salinity of MW used in the studies reported here were not very ...
Seasonal plankton blooms correlate with occurrence of cholera in Bangladesh, although the mechanism of how dormant Vibrio cholerae, enduring interepidemic period in biofilms and plankton, initiates seasonal cholera is not fully understood. In this study, laboratory microcosms prepared with estuarine Mathbaria water (MW) samples supported active growth of toxigenic V. cholerae O1 up to 7 weeks as opposed to 6 months when microcosms were supplemented with dehydrated shrimp chitin chips (CC) as the single source of nutrient. Bacterial counting and detection of wbe and ctxA genes were done employing culture, direct fluorescent antibody (DFA) assay, and multiplex-polymerase chain reaction methods. In MW microcosm, the aqueous phase became clear as the non-culturable cells settled, whereas the aqueous phase of the MW-CC microcosm became turbid from bacterial growth stimulated by chitin. Bacterial chitin degradation and biofilm formation proceeded from an initial steady state to a gradually declining ...
As Yemen faces its fourth year of war, the country also fights a looming health crisis. The cholera health crisis in Yemen affects 22 of 23 governorates and almost 299 of Yemens 333 districts. Recording over one million cholera cases in 2017, Yemens crisis is the worst cholera epidemic on record.. Driven by years of war, the country has experienced a significant collapse in access to food, safe drinking water and health care. With millions of Yemenis facing famine, malnourishment increases the risk of cholera infections becoming fatal.. Many organizations are on the ground in Yemen, treating as many cholera cases as possible. Organizations responding to the health crisis in Yemen include Médecins Sans Frontières (MSF) or Doctors Without Borders, Save the Children, Islamic Relief Foundation and World Health Organization (WHO).. If left untreated, the mortality rate of cholera can be very high. With proper treatment, cholera is very easy to cure. The problem is that it is not easy for cholera ...
January 3, 2014. California-based vaccine manufacturer PaxVax has reportedly submitted an application to begin international trials of a novel oral cholera vaccine that contains live, genetically modified (GM) bacteria. reports that the new vaccine is set to be tested on more than 1,000 individuals, many of whom are young children, in a three-part clinical trial series to take place throughout Australia.. In a recent application filing with the Australian Government, PaxVax makes plain its intent to administer the live, GM bacteria in both young and old and in every region of the country. Participants will be instructed to literally consume a cocktail of mercury-resistant, GM Shigella flexneri NR1 bacteria derived from the Vibrio cholera bacterial strain, which is recognized as the causative agent of the gastroenteritis disease known as cholera.. According to the filing, the GM cholera strain used in the vaccine has essentially been artificially neutralized to prevent the toxic ...
In addition to improved water supply and sanitation, the two-dose killed oral cholera vaccine (OCV) is an important tool for the prevention and control of cholera. We aimed to document the immunogenicity and protection (efficacy and effectiveness) conferred by a single OCV dose against cholera. The meta-analysis showed an estimated 73% and 77% of individuals seroconverted to the Ogawa and Inaba serotypes, respectively, after an OCV first dose. The estimates of single-dose vaccine protection from available studies are 87% at 2 months decreasing to 33% at 2 years. Current immunologic and clinical data suggest that protection conferred by a single dose of killed OCV may be sufficient to reduce short-term risk in outbreaks or other high-risk settings, which may be especially useful when vaccine supply is limited. However, until more data suggests otherwise, a second dose should be given as soon as circumstances allow to ensure robust protection.. ...
Cholera is still a major cause of disease epidemics in sub-Saharan Africa (SSA). During the period January 2017-March 2018, 15 countries in the WHO African Region (AFR) reported cholera outbreaks of varying magnitudes. Zimbabwe has experienced cholera outbreaks dating as far back as 1971 with an unprecedented outbreak occurring in 2008/2009 when 60 of the 62 districts in the country were affected. The outbreak was declared over in May 2009 and by then, 98,592 cases and 4288 deaths had been reported. In Zimbabwe, outbreaks have occurred against a backdrop of a struggling economy and a weak health system. The role of a resilient health system in emergencies response is accentuated premised on experiences from the Ebola outbreak that largely affected three countries in West Africa. Amidst economic and persistent system wide challenges faced by Zimbabwe, preparedness and response capacity has been built over the years. This is evidenced by the rapid response and containment of the recent cholera outbreak.
Since mid-August 1986, 12 cases of cholera have been identified among residents of Louisiana. The cases occurred in nine families living in New Orleans and in other towns in six parishes (Jefferson, LaFourche, Assumption, St. Mary, Iberia, and Jefferson Davis) within a 200-mile radius to the south and west of New Orleans. None of the patients had traveled abroad within the past year. Onset of symptoms occurred between August 8 and October 1. Ten of the patients had severe diarrhea, seven required hospitalization, and four required treatment in an intensive care unit for hypotension. All patients recovered following intravenous fluid therapy. Seven patients had stool cultures yielding toxigenic Vibrio cholerae O1, biotype El Tor, serotype Inaba. The remaining five patients did not have stool cultures performed but had vibriocidal antibody titers greater than or equal to 1280, suggesting recent infection with V. cholerae O1. Sewer system surveillance using Moore swabs has detected toxigenic V. ...

Diarrhoea is a major health problem throughout the world, and responsible for high morbidity and mortality in Nepal. The crosssectional prospective study was carried out to screen ESBL producer from MDR Vibrio Cholerae, Salmonella and Shigella from 268 diarrhoeal stools from Nepalgunj Cholera outbreak and different hospitals of Nepal during April 2010 to January 2011. The specimens were processed by standard microbiological methods and confirmed with serology. Altogether 14.18% of bacteria were isolated with 8.21% V. cholerae O1 El Tor Ogawa, 2.24% Shigella flexneri B and 3.73% Salmonella spp. Highest bacterial culture (47.36%) were isolated in Kathmandu while highest V. cholerae (77.27%) were isolated in Nepalgunj. The highest number of Salmonella spp. and Shigella spp. were isolated from Kanti Childrens Hospital. Highest bacteria isolation (47.36%) and highest V. cholerae isolation (81.81%) were observed in the August. The bacteria isolation was significantly associated with places and months ...

A CDC collaborative study including Dr. Isaac Fung (formerly of the CDC), assistant professor of epidemiology at Georgia Southern University Jiann-Ping Hsu College of Public Health, examines preventive interventions through modeling the effect of water, sanitation and hygiene, and oral cholera vaccine implementation in Haiti. In 2010, toxigenic Vibrio cholerae was newly introduced to Haiti. Because resources are limited, decision-makers need to understand the effect of different preventive interventions. The team built a static model to estimate the potential number of cholera cases averted through improvements in coverage in water, sanitation and hygiene (WASH) (i.e., latrines, point-of-use chlorination, and piped water), oral cholera vaccine (OCV), or a combination of both. The authors allowed indirect effects and non-linear relationships between effect and population coverage. Because there are limited incidence data for endemic cholera in Haiti, the authors estimated the incidence of cholera over 20
Abstract Cholera is a secretory diarrhoeal disease caused by infection with Vibrio cholerae, primarily the V. cholerae O1 El Tor biotype. There are approximately 2.9 million cases in 69 endemic countries annually, resulting in 95 000 deaths. Cholera is associated with poor infrastructure and lack of access to sanitation and clean drinking water. The current cholera epidemic in Yemen, linked to spread of V. cholerae O1 (Ogawa serotype), is associated with the ongoing war. This has devastated infrastructure and health services. The World Health Organization had estimated that 172 286 suspected cases arose between 27th April and 19th June 2017, including 1170 deaths. While there are three oral cholera vaccines prequalified by the World Health Organization, there are issues surrounding vaccination campaigns in conflict situations, exacerbated by external factors such as a global vaccine shortage. Major movements of people complicates surveillance and administration of double doses of vaccines. ...
Surveillance was conducted during February and March 1991 in the pediatric emergency department of Cayetano Heredia Hospital, Lima, Peru, to contrast the characteristics of children with epidemic cholera with those of children with non-cholera-associated diarrhea. Among 626 patients 14 years of age or younger, Vibrio cholerae O1 was isolated...
DNA microarray technology is revolutionizing the field of bacterial pathogenesis by allowing researchers to monitor the expression of thousands of genes during the course of an in vitro or in vivo experiment. In this report, we have applied this technology to conduct a genome-wide search for V. cholerae genes belonging to the ToxR regulon, the key group of genes responsible for the virulence properties of this organism in humans. We also used microarrays to analyze the transcriptional state of vibrios shed from cholera patients.. We first compared the gene expression profiles of V. cholerae toxRS, tcpPH, and toxT mutants that were grown under in vitro conditions that are optimal for the expression of CT by El Tor O1 and O139 strains of V. cholerae. The transcriptional profile of the toxT mutant revealed the presence of few new ToxT-regulated genes. Newly identified genes include VC1091 (oligopeptide periplasmic binding protein), VC1835 (pal); VC2766 (atpA); VCA0059 (lpp); VCA0732 (conserved ...
By Makini Brice | LES CAYES, Haiti LES CAYES, Haiti Haiti has launched a massive cholera vaccination campaign to battle a flare-up after Hurricane Matthew, but concerns remain about the capacity for longer-term improvements to water and sanitation infrastructure needed to eradicate the disease. The cholera campaign, launched on Tuesday in two southern areas hammered by the storm, is aiming to be the worlds largest, targeting 820,000 people, said Ernsly Jackson, an immunization specialist for UNICEF Haiti. Haiti has battled a cholera outbreak that has sickened more than 800,000 people and killed about 9,000 since 2010, when the bacteria was imported into the country by a contingent of United Nations peacekeepers. Although it had proved stubborn to eradicate, cases had declined sharply from a peak in 2010-11. But Hurricane Matthew struck the island in early October, killing up to 1,000 people, leaving about 1.4 million in need of humanitarian assistance and damaging many health facilities.

As the world faced a dearth of oral cholera vaccines, the United Nations health agency announced that the supply of medication will double up to six million doses this year after it added another producer to its list of approved suppliers so that they can put up a fight against a disease that kills as many as 142,000 people every year
In research done over the past seven years, Pascual and colleagues have found evidence that a phenomenon known as the El Nino-Southern Oscillation (ENSO), a major source of climate variability from year to year, influences cycles of cholera in Bangladesh. They also showed that the coupling between climate variability and cholera cycles has become stronger in recent decades.. Now, Pascual is examining the feasibility of using a model developed during that work as an early warning system. The question we asked was whether, using data from 1966 to 2000, we could have predicted cholera outbreaks over the past five years, said Pascual, an associate professor of ecology and evolutionary biology. We also wanted to know whether incorporating ENSO into the model would improve the accuracy of our predictions. The challenge for the model was particularly interesting because the past five years were atypical, with fewer cholera cases than usual and no strong climate anomalies. However, the model ...
An outbreak of cholera in Hidalgo State and the neighboring Federal District of Mexico City has caused 79 cases of disease, including one fatality. The source of the outbreak is still unclear.. The strain of cholera currently affecting Mexico is Vibrio cholerae O:1 Ogawa toxigenic. Prior to this outbreak, cholera has not been seen in Mexico in just over ten years. PAHO and the WHO included Mexico in its latest Epidemiological Alert.. Cholera is an acute, diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. This bacterium is usually found in contaminated water or food sources, but it can also be found in the environment, in rivers and coastal waters. An estimated 3 - 5 million cases and over 100,000 deaths occur globally each year. However, if treated properly with prompt rehydration, fewer than 1 percent of cholera patients die.. Individuals can avoid infection with cholera by drinking only bottled, boiled, or treated water, and by washing hands often with ...
Sharing results of the clinical study, Dr. Ajit Pal Singh- Vice President Clinical R&Dat Hilleman Labsstated, HillcholTM was tested in 840 subjects that included adults, adolescents as well as small children. We were able to demonstrate safety and tolerability of HillcholTM in our Phase I/II trials. Our vaccine consists of a novel Hikojima strain that expresses both the Ogawa and Inaba serotypes. When compared against Shanchol, the Cholera vaccine pre-qualified by WHO, we could achieve non-inferiority in terms of seroconversion as well as Geometric Mean Titre for both the Ogawa and Inaba serotypes. These results are very encouraging and warrant further development of our Cholera vaccine.. Dr. Tarun Sharma, Director R&D at Hilleman Labsstated, The HillcholTM Phase I/II clinical trial results support our Hikojima vaccine design and mirror the impressive results we have been able to achieve in Preclinical studies. This encourages us to conduct further clinical studies as well as undertake ...
The rapidly spreading cholera outbreak in Yemen has exceeded 200,000 suspected cases, increasing at an average of 5,000 a day. We are now facing the worst cholera outbreak in the world.. In just two months, cholera has spread to almost every governorate of this war-torn country. Already more than 1,300 people have died - one quarter of them children - and the death toll is expected to rise. More. ...
A cholera outbreak in war-ravaged Yemen has killed 242 people, and left nearly 23,500 others sick in the past three weeks alone, the World Health Organization said Friday. The UN health agency said that in the past day alone, 20 cholera deaths and 3,460 suspected cases had been registered in the country, where two-thirds of the population is on the brink of famine. The speed of the resurgence of this cholera epidemic is unprecedented, WHO representative for Yemen Nevio Zagaria told reporters in Geneva by phone from Yemen, warning that a quarter of a million people could become sick by the end of the year. Cholera is a highly contagious bacterial infection spread through contaminated food or water. Reining in the disease is particularly complicated in Yemen, where two years of devastating war between the Huthis and government forces backed by a Saudi-led Arab military coalition has left more than half the country`s medical facilities out of service. Zagaria pointed out that humanitarian workers ...
With 1,000 people already dead from cholera in Angola, the United Nations Childrens Fund (UNICEF) is appealing for $1 million to fight the most severe outbreak of the disease there since 1988.. According to the World Health Organization (WHO), the ongoing rainy season has made it likely that the epidemic will spread further despite efforts by UNICEF, WHO, the Angolan Government and other partners to get care and medication to the sick.. Cholera, an acute intestinal disease caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae, causes copious, painless, watery diarrhoea that can quickly lead to severe dehydration and death if treatment, including rehydration, is not given promptly. Vomiting also occurs in most patients.. Apart from significant human suffering, the disease disrupts social and economic structures and puts tremendous strain on already precarious national health systems. Seasonal factors, such as the rainy season, contribute to the diseases ...
Time is ticking as aid organizations wait to launch a vaccination campaign against cholera in Haiti. The heavy seasonal rains have already begun to fall, and threaten to bring flooding, contaminated water, and increased cholera incidence with them. But Haitian officials have not yet approved the plans of nongovernmental organizations Partners in Health (PIH) and GHESKIO to vaccinate 100,000 people against cholera. Here, we chronicle the major events that led to this standoff.. Cholera Arrives in 2010. After the January 2010 earthquake, Haiti was the focus of much international attention and relief assistance. Less than a year later, a massive cholera outbreak hit the country, centered around the Artibonite River Valley and likely imported by UN staff from Nepal. In the year and a half since, there have been an estimated 530,000 cases and 7,000 deaths.. At the time of the initial outbreak, the Pan American Health Organization (PAHO) stated that a cholera vaccination campaign was not an ...

Each day there are more than 5,000 new cases of the waterborne disease, which causes acute diarrhea and dehydration, in the country where the health system has collapsed after more than two years of war, it said.. The total number of suspected cholera cases in Yemen this year hit the half a million mark on Sunday, and nearly 2,000 people have died since the outbreak began to spread rapidly at the end of April, the WHO said in a statement.. The spread of cholera has slowed significantly in some areas compared to peak levels, but the disease is still spreading fast in more recently affected districts, which are recording large numbers of cases, it said, reporting a total of 503,484 cases.. The disease, spread by ingestion of food or water tainted with human faeces, can kill within hours if untreated. It has been largely eradicated in developed countries equipped with sanitation systems and water treatment. But Yemens devastating civil war, pitting a Saudi-led military coalition against the ...
A high number of cholera cases have been found in the small city of Wasu in the first known cholera outbreak in Papua New Guinea in 50 years.

The United Nations has apologized for its response to the cholera outbreak in Haiti that claimed more than 9,000 lives and has pledged to provide both immediate and long-term support for those affected.. Over the last six years, cholera has afflicted nearly 800,000 people on the Caribbean island.. Daniel Dickinson has more details. Speaking at the UN on Thursday, the Secretary-General, Ban Ki-moon apologized for the loss of life and suffering caused by the cholera outbreak in Haiti.. On behalf of the United Nations, I want to say very clearly: we apologize to the Haitian people. We simply did not do enough with regard to the cholera outbreak and its spread in Haiti. We are profoundly sorry for our role.. He added that the outbreak had cast a shadow on the relationship between the United Nations and the people of Haiti.. It is a blemish on the reputation of UN peacekeeping and the Organization world-wide. For the sake of the Haitian people, but also for the sake of the United Nations itself, ...
Vibrio cholerae is the etiological agent of the acute intestinal disorder cholera. The source of cholera infection is typically fecal contamination of potable water sources. V. cholerae is able to colonize the host intestine and trigger the onset of cholera symptoms due to the expression of two primary virulence factors: cholera toxin (CT) and the toxin-coregulated pilus (TCP). TCP is a type IVb pilus encoded by the tcp operon. While many components encoded within the tcp operon have been well characterized, there remain two that we know little about: TcpB and TcpS. In this work, we take a genetic approach to initiate the characterization of each of these pilus components. We have found the large putative pilin, TcpB is not requisite for formation of a pilus structure, but remains essential for all TCP functions. The formation of TCP by a tcpB null mutant represents a surprising finding that has led to a new research emphasis with respect to TCP functions. Additionally, we have characterized the ...

Flow cytofluorometric DNA analysis was applied to determine of the relative contents of proliferative (more then 2C DNA per cell) and apoptotic (less then 2C DNA per cell) leukocytes in blood of adult rabbits, challenged with 10,000 times the 50 % effective dose of Vibrio cholerae virulent strain by the RITARD technique. It has been shown that irreversible increase the percentage of cells carrying DNA in the degradation stage brings to disbalance between the genetically controlled cell proliferation and apoptosis that leads to animal death from the cholera infection. Such fatal changes were not observed in challenging of immunized animals that were not died. Thus received data show that the flow cytofluorometric measurements may be used for detection of transgressions in homeostasis during acute infection diseases, for outlet prognosis of the cholera infection ...

  • The disease is contracted 'by drinking water or eating food contaminated with the cholera bacterium,' the Centers for Disease Control and Prevention (CDC) said on its Web site. (
  • THE toxin that makes cholera lethal belongs not to the cholera bacterium itself, but to a threadlike virus which hijacks it to hitch a ride into cells. (
  • We've seen it so far moving between two strains of Vibrio cholerae [the cholera bacterium] but there is no reason why it should not move from, say, V. cholerae to Shigella," says Mekalanos. (
  • Their suspicions were roused when they found that the sequence of genes which encodes the cholera toxin in disease-causing strains is capable of jumping from one bacterium to another. (
  • Cholera is an acute infectious disease caused by a bacterium, Vibrio cholerae (V. cholerae), which usually results in a painless, watery diarrhea in humans. (

  • But, he warns, it doesn't bode well for experimental cholera vaccines based on live, weakened bacteria whose toxin genes have been removed. (
  • Cholera is usually spread by eating food or drinking water that is contaminated with the bacteria that cause cholera (Vibrio cholerae). (
  • Yet because they shed cholera bacteria in their stool for seven to 14 days, they can still infect others through contaminated water. (
  • The discovery of a new species of the cholera bacteria (O139) in Bangladesh in 1992, which has since been detected in 11 countries, has raised the possibility and fear of an eighth pandemic. (

  • Cholera is caused by bacteria, and spread through contaminated food or water. (
  • The cause of cholera is infection by the V. cholera bacteria. (
  • V. cholera bacteria live in shallow, salty water on microscopic crustaceans. (

  • The vaccine consists of harmless, lab-designed bacteria don't cause cholera. (
  • Cholera bacteria conserve energy and stored nutrients while passing through the highly acidic environment of the stomach which, thanks to Cholera's sensitivity to acid, is successful in killing a majority of bacteria, but children, older adults, and people who take antacids have lower levels of stomach acid, so they lack this first line of defense. (
  • Although signs and symptoms of severe cholera can be unmistakable in areas where it's common, the only way to confirm a diagnosis is to identify the bacteria in a stool sample. (

  • Prevention methods against cholera include improved sanitation and access to clean water . (
  • [2] [11] Cholera occurs as both outbreaks and chronically in certain areas . (
  • In studies of travellers to countries or areas reporting cholera outbreaks, WC/rBS was found also to induce approximately 50% short-term protection against diarrhoea caused by enterotoxigenic Escherichia coli (ETEC).Two closely related bivalent oral cholera vaccines are available in India and Viet Nam. (
  • They are reported to be safe and efficacious, providing 66-67% protection for at least 2 years against clinically significant cholera in countries or areas reporting outbreaks. (
  • Cholera outbreaks have occurred in Mozambique every year for the past five years. (
  • In these regions, cholera is not a regular occurrence but may sometimes occur as outbreaks, especially during the summer season, natural disasters, wars or civil disorders. (
  • The World Health Organization (WHO) has maps of current and past areas with cholera outbreaks (see WHO reference). (
  • Outbreaks of cholera in 2015-2016 include South Sudan, United Republic of Tanzania, and Kenya, with over 216 deaths and most recently, 121 people diagnosed with cholera in Iraq, their first outbreak since 2012 and in Cuba, the first outbreak in over 130 years. (
  • Poor sanitation (e.g., untreated water, cooks not washing their hands) is the main cause of cholera outbreaks. (
  • If you're in an area known for cholera outbreaks, the best way to avoid the disease is to wash your hands religiously and to avoid eating any raw foods, including salad s and fruit. (
  • Researchers have developed a system for predicting cholera outbreaks using satellite monitoring of marine environments. (
  • They show cholera outbreaks follow seasonal increases in sea temperature. (
  • They found cholera outbreaks in Kolkata (Calcutta) in India and Matlab in Bangladesh occurred soon after seasonal rises in sea temperature which in turn lead to increases in phytoplankton densities. (
  • Professor Rita Colwell, from the Institute for Advanced Computer Studies at the University of Maryland has been studying cholera outbreaks for over 30 years. (
  • The researchers hope to soon be able to predict cholera outbreaks weeks or even months before they occur by using satellite monitoring, looking at what is happening further out to sea, examining the timings of ocean currents and associated growths in plankton numbers. (
  • Oral vaccines are another powerful tool being used more and more to help prevent cholera and to contain outbreaks. (
  • GENEVA (AP) - World Health Organization officials said Friday that famine-hit Somalia faces a cholera epidemic as dirty water and poor sanitation are leading to an increase in outbreaks of the disease. (
  • Quick confirmation helps to decrease death rates at the start of cholera outbreaks and leads to earlier public health interventions for outbreak control. (
  • Major cholera outbreaks occur in two dominant forms: (a) epidemic, characterized by a sudden and sporadic occurrence of a large number of cholera cases and (b) endemic, in which human cholera cases occur on annual scales with distinct and characteristic seasonality. (
  • Travellers living and working in areas with cholera outbreaks, including refugee camps, are at increased risk - particularly those a weakened immune system, persons who have had surgery for duodenal or gastric ulcers or taking antacid therapy, and cannabis users (smoking marijuana reduces stomach acid secretion). (
  • While there are more than 200 different serogroups only the O1 and the O139 strains have been known to cause epidemic and pandemic outbreaks of disease, using a toxin-coregulated pilus (TCP) and cholera toxin (CT), which other strains lack. (
  • The surge underscores how Yemen, which has endured multiple outbreaks of cholera amid four years of civil war, still isn't able to stop its spread. (
  • In the late twentieth century, oral cholera vaccines started to be used on a massive scale, with millions of vaccinations taking place, as a tool to control cholera outbreaks in addition to the traditional interventions of improving safe water supplies, sanitation, handwashing and other means of improving hygiene. (
  • The World Health Organization (WHO) recommends both preventive and reactive use of the vaccine, making the following key statements: WHO recommends that current available cholera vaccines be used as complements to traditional control and preventive measures in areas where the disease is endemic and should be considered in areas at risk for outbreaks. (
  • Vaccination should not disrupt the provision of other high priority health interventions to control or prevent cholera outbreaks. (
  • Reactive vaccination might be considered in view of limiting the extent of large prolonged outbreaks, provided the local infrastructure allows it, and an in-depth analysis of past cholera data and identification of a defined target area have been performed. (
  • A vaccine consisting of killed whole-cell V. cholerae O1 in combination with a recombinant B-subunit of cholera toxin (WC/rBS) has been marketed since the early 1990s. (
  • Cholera toxin B pentamer, Vibrio cholerae. (
  • The cholera toxin is an oligomeric complex made up of six protein subunits: a single copy of the A subunit (part A, enzymatic, P01555 ), and five copies of the B subunit (part B, receptor binding, P01556 ), denoted as AB 5 . (
  • Cholera toxin acts by the following mechanism: First, the B subunit ring of the cholera toxin binds to GM1 gangliosides on the surface of target cells. (
  • The gene encoding the cholera toxin is introduced into V. cholerae by horizontal gene transfer . (
  • Treatment of cultured rodent neural stem cells with cholera toxin induces changes in the localization of the transcription factor Hes3 and increases their numbers. (
  • EDLB (specifically the Epidemic Investigations Laboratory) requests that state public health labs immediately forward all suspect V. cholerae isolates for serogrouping and cholera toxin testing as well as biotype and antimicrobial susceptibility testing. (
  • Pathogenic O1 and O139 V. cholerae have the ability to produce cholera toxin, a type of enterotoxin that affects intestinal cells. (
  • It gets attached to the microvilli of the epithelial cells of the intestinal tract where it multiplies and produce a potent enterotoxin known as cholera toxin. (
  • Cholera toxin is responsible for increased secretion of water and electrolytes in stools from the intestinal cells leading to dehydration, shock, acidosis and death. (
  • Licensed newer generation vaccines are given orally and consist either of killed cholera Vibrio whole cells, with or without a nonpathogenic fragment of cholera toxin, or of live genetically attenuated organisms ( 5 ). (
  • The case for introducing oral cholera vaccines as routine public health tools has also been strengthened by an apparent increase in the magnitude, severity, and duration of recently reported epidemics, such as those observed in Angola, Zimbabwe, Vietnam, and Haiti, perhaps related to the widespread emergence of the modified genetic forms of V. cholerae 01 El Tor biotype that produce classical biotype cholera toxin ( 10 ). (
  • Interestingly, immune responses to the toxin do not protect against cholera, but previous research led by investigator Edward Ryan, MD, director of Global Infectious Diseases at MGH, has shown antibodies that bind V. cholerae's sugar coating-called O-specific polysaccharide (OSP)-do offer protection. (
  • Scientists at the University of California-San Diego say they have uncovered a biochemical mechanism that helps make cholera toxin (CT) so deadly. (
  • Studying fruit flies, mice, and cultured human intestinal cells, researchers looked at cholera toxin, which is produced by Vibrio cholerae . (
  • The study built on research published decades ago, when scientists discovered that cholera toxin caused the overproduction of small chemical messenger molecule cyclic adenosine monophosphate, or "cAMP," in epithelial cells lining the intestine. (
  • The molecular mechanism by which this massive flux of sodium and water into the gut occurs as a result of the cholera toxin remained a mystery until Annabel Guichard, Ph.D., a research scientist working in Dr. Bier's laboratory and the lead author of the paper, began conducting experiments that spearheaded the two groups' collaboration. (
  • The UC San Diego researchers found that cholera toxin acts by two entirely distinct but cooperating mechanisms to produce diarrhea. (
  • The scientists showed that many of the effects of the cholera toxin on the gut could be reversed by genetic manipulations that bolster the delivery of proteins to these junctions. (
  • The differences are 203 single-nucleotide polymorphisms, the absence of three genomic islands, and an increased number of tandem cholera toxin prophage (CTX) arrays. (
  • The Dukoral monovalent vaccine from Sweden, which combines formalin, heat-killed whole cells of Vibrio cholerae O1 and a recombinant cholera toxin B subunit, was licensed in 1991, mainly for travellers. (
  • WC-rBS (marketed as "Dukoral") is a monovalent inactivated vaccine containing killed whole cells of V. cholerae O1 plus additional recombinant cholera toxin B subunit. (
  • With support from UNICEF, national and local health authorities have provided logistical support to set up and supply cholera treatment centers with consumable, medication, and infection prevention and control supplies. (

  • cholera /article.htm#:~:text=Cholera is an acute infectious disease caused by,dehydration so severe it can lead to death. (
  • Cholera is highly treatable , but because dehydration can happen quickly, it's important to get cholera treatment right away. (
  • Cholera symptoms and signs include a rapid onset of copious, smelly diarrhea that resembles rice water and may lead to signs of dehydration (for example, vomiting , wrinkled skin, low blood pressure , dry mouth , rapid heart rate). (
  • A person with cholera can quickly lose fluids, up to 20 liters a day, so severe dehydration and shock can occur. (
  • A doctor may suspect cholera if a patient has severe watery diarrhea, vomiting, and rapid dehydration, especially if they have recently traveled to a place that has a recent history of cholera, or poor sanitation, or if they have recently consumed shellfish. (
  • It is normally dehydration that leads to death from cholera, so the most important treatment is to give oral hydration solution (ORS), also known as oral rehydration therapy (ORT). (
  • People with cholera are primarilly treated for dehydration. (
  • these drugs will shorten the course of the disease, but cholera generally runs its course and the patient will recover on his or her own if the dehydration is taken care of. (
  • BOSTON - Findings from a team led by investigators at Massachusetts General Hospital (MGH), reported in the online journal mBio , may help scientists develop a more effective vaccine for cholera, a bacterial disease that causes severe diarrhea and dehydration and is usually spread through contaminated water. (
  • Cholera itself causes diarrhoea and vomiting, leading to severe dehydration. (
  • Since severe dehydration and death can occur within hours, cholera needs to be treated immediately. (
  • In most developing countries, you can buy powdered packets of oral rehydration salts (ORS) originally developed by the World Health Organization to treat diarrhea and dehydration in infants with cholera. (
  • Antibiotics can shorten the length of illness and help prevent fluid loss (dehydration) in people with severe cholera. (
  • If left untreated, diarrhea from cholera can cause severe dehydration. (
  • Severe cholera can lead to profuse diarrhea and vomiting, causing dehydration. (
  • Cholera epidemics can also sometimes happen after a disaster (like an earthquake or flood) if people are living in tent cities or other places without running water or proper sanitation systems. (
  • In the past two centuries, seven pandemics (global epidemics) of cholera have carried the disease to countries around the world. (
  • The purpose of this lesson is to explore sources which reveal something about the contemporary medical understanding of the disease, public attitudes and the role of the General Board of Health over a time frame of series of cholera epidemics in Victorian England. (
  • This could provide an early warning system for India and Bangladesh where cholera epidemics occur regularly. (
