Necator americanus (human hookworm) aspartyl proteinases and digestion of skin macromolecules during skin penetration. (1/40)

The infective larvae of Necator americanus were shown to secrete all mechanistic classes of proteolytic enzymes with two overall pH optima of 6.5 and 8.5 using fluorescein isothiocyanate-labeled casein as the substrate. Since infective larvae are obligate skin penetrators, the effect of each of these enzyme classes against macromolecules derived from human skin was examined. Larval secretions were shown to degrade collagen types I, III, IV, and V, fibronectin, laminin, and elastin. All the skin macromolecules tested were hydrolyzed by aspartyl proteinase activity, which was inhibitable by pepstatin A. Collagen and elastin was also hydrolyzed by metalloproteinase activity, while the serine proteinase activity hydrolyzed only elastin. As a consequence of these experiments, the effect of proteinase inhibitors on the penetration of live larvae through hamster skin was tested. Larval penetration was significantly inhibited only by pepstatin A, confirming the importance of the aspartyl proteinase activity during the skin penetration process.  (+info)

Geographic distribution and epidemiology of Oesophagostomum bifurcum and hookworm infections in humans in Togo. (2/40)

In contrast to the rest of the world, infections with Oesophagostomum bifurcum are commonly found in humans in northern Togo and Ghana. In addition, infections with hookworm are endemic in this region. In the present study, a detailed map of the geographic distribution of O. bifurcum and hookworm infections in northern Togo was made. There were a number of foci with high prevalence of infection with O. bifurcum. All the villages examined were infected with hookworm, and the distribution was quite patchy. Women were infected with O. bifurcum more often than men, while infections with hookworm were more prevalent in men than in women. The prevalence and intensity of infection with both parasites were clearly age-dependent. We estimate that more than a 100,000 people in Togo are infected with O. bifurcum and more than 230,000 are infected with hookworm.  (+info)

Determining the prevalence of Oesophagostomum bifurcum and Necator americanus infections using specific PCR amplification of DNA from faecal samples. (3/40)

Until recently infection of humans with Oesophagostomum bifurcum was regarded as a rare zoonosis. But in northern Togo and Ghana its prevalence is 50% or more in certain villages. Diagnosis is hampered by the fact that the eggs of O. bifurcum are morphologically identical to those of the hookworm Necator americanus. Stools have to be cultured for 7 days to allow eggs to hatch to the characteristic third-stage (L3) larvae. We evaluated the applicability of specific polymerase chain reactions (PCRs) to amplify DNA from faecal samples as an alternative method for the differential diagnosis of the two infections. Oesophagostomum bifurcum-PCR was positive in 57 of 61 faecal samples known to contain O. bifurcum L3 larvae in coproculture. Necator americanus PCR was positive in 137 of 146 faecal samples known to contain N. americanus L3 larvae in coproculture. PCR also detected 26 additional O. bifurcum cases in 72 samples from O. bifurcum endemic villages in which no O. bifurcum larvae were found and 45 N. americanus cases in 78 samples in which no N. americanus larvae were found in coproculture. No O. bifurcum DNA was detected in 91 stool samples from individuals from two non-endemic villages. These results prove the usefulness of specific PCR assays as epidemiological tools to estimate the prevalence of O. bifurcum and N. americanus infections in human populations.  (+info)

Emerging patterns of hookworm infection: influence of aging on the intensity of Necator infection in Hainan Province, People's Republic of China. (4/40)

We examined risk factors associated with Necator americanus infection among persons aged > or =50 years in Hainan Province, People's Republic of China. Age and sex made the most important contributions to the variation in infection intensity (28%-30%), with age alone responsible for 27% of this variation. When stratified by 20-year age intervals, the influence of shared residence was 23% for persons aged > or =50 years and 27% for those aged <20 years, who had the highest and lowest levels of infection intensity, respectively. This points to shared residence as a means of capturing the complex relationship between aging and shared socioeconomic, environmental, and behavioral factors that influence transmission of Necator infection. None of the other 26 personal or 32 household risk factors were found to be significant. The importance of aging in Necator infection reveals an emerging public health problem among the elderly population of developing countries.  (+info)

Hookworm (Necator americanus) transmission in inland areas of sandy soils in KwaZulu-Natal, South Africa. (5/40)

This study extended the association between hookworm transmission in KwaZulu-Natal and the sandy coastal plain by investigating the parasite's occurrence in isolated areas of sandy soils further inland. A school-based prevalence survey was carried out in selected inland sandy areas and in surrounding areas dominated by clay soils within a narrow altitudinal range of between 500 and 700 m to reduce the effect of altitude on climate-related factors (rainfall and temperature). Sandy areas situated on the coastal plain were included in the analysis for comparative purposes. Soil samples (0-50 mm depth) were collected from each locality to assess their nematode loadings and to analyse selected physical and chemical properties. Significant differences were found between the moderate prevalence of hookworm infection among children living in inland areas with sandy soils (17.3%) and the low prevalence in surrounding non-sandy areas (5.3%, P < 0.001), and between infection among children living in all inland areas (9.3%) and the high prevalence on the coastal plain (62.5%, P < 0.001). Amounts of fine and medium sand were highest in both the coastal plain soils and in inland sandy areas and these fractions showed a significant positive correlation with hookworm prevalence and nematode loadings. Clay, coarse sand and organic matter contents were highest in surrounding non-sandy soils and showed a significant negative correlation with the nematode variables. No statistically significant correlations were found with soil pH at study localities. We conclude that properties of inland sandy soils, particularly particle size distribution, correlate well with hookworm prevalence and nematode loadings and therefore provide a more suitable habitat for nematodes than surrounding non-sandy areas. These results suggest that particle size distribution of sand fractions, organic matter and clay content in the soil influence the survival of hookworm larvae and hence the parasite's transmission.  (+info)

Cellular responses and cytokine production in post-treatment hookworm patients from an endemic area in Brazil. (6/40)

Human hookworm infections are distributed widely in tropical areas and have a significant impact on host morbidity and human health. In the present study, we investigated the cellular responsiveness and cytokine production in peripheral blood mononuclear cells (PBMC) from Necator americanus-infected schoolchildren who had recently received chemotherapy, and compared them with non-infected endemic controls. Hookworm patients and treated, egg-negative individuals showed a lower cellular reactivity against phytohaemagglutinin (PHA) and hookworm antigen when compared with egg-negative endemic controls. The baseline production of proinflammatory tumour necrosis factor-alpha (TNF-alpha) in PBMC from infected patients and treated, egg-negative individuals was elevated. On the other hand, PHA- or hookworm antigen-induced interleukin (IL)-12 and interferon (IFN)-gamma secretion was higher in endemic controls than in hookworm patients, who either continued egg-positive or were egg-negative after treatment. Also, PBMC from endemic controls secreted more IL-5 and IL-13 than the other patient groups. Opposite to that, the spontaneous as well as the antigen-driven IL-10 secretion was lower in endemic controls when compared with the other groups. In summary, patently hookworm-infected as well as egg-negative treated patients disclosed an elevated spontaneous cellular secretion of proinflammatory TNF-alpha, a prominent secretion of regulatory Th2-type IL-10 and an impaired production of IL-12, IFN-gamma, IL-5 and IL-13.  (+info)

Immune responses in human necatoriasis: association between interleukin-5 responses and resistance to reinfection. (7/40)

Cytokine and proliferative responses to Necator americanus infection were measured in a treatment-reinfection study of infected subjects from an area of Papua New Guinea where N. americanus is highly endemic. Before treatment, most subjects produced detectable interleukin (IL)-4 (97%), IL-5 (86%), and interferon (IFN)- gamma (64%) in response to adult N. americanus antigen. Pretreatment IFN- gamma responses were negatively associated with hookworm burden, decreasing by 18 pg/mL for each increase of 1000 eggs/gram (epg) (n=75; P<.01). Mean IFN- gamma responses increased significantly after anthelmintic treatment, from 166 to 322 pg/mL (n=42; P<.01). The intensity of reinfection was significantly negatively correlated with pretreatment IL-5 responses, decreasing by 551 epg for each 100 pg/mL increase in production of IL-5 (n=51; P<.01). These data indicate that there is a mixed cytokine response in necatoriasis, with worm burden-associated suppression of IFN- gamma responses to adult N. americanus antigen. Resistance to reinfection is associated with the parasite-specific IL-5 response.  (+info)

Polymerase chain reaction-based differential diagnosis of Ancylostoma duodenale and Necator americanus infections in humans in northern Ghana. (8/40)

We evaluated a two-step semi-nested polymerase chain reaction (PCR)-based approach for the specific detection of Ancylostoma duodenale DNA in human faeces. The test was used to determine to what extent this species of hookworm is present in the regions of Bolgatanga and Garu of northern Ghana. Initially, the sensitivity and specificity of the PCR were tested using a range of well-defined control samples. Subsequently, a total of 378 human faecal DNA samples from Bolgatanga and Garu were subjected to the PCR. The results were compared with those obtained using a previously established PCR for the specific detection of Necator americanus DNA in human faeces. Infection with A. duodenale was recorded in 74 (19.6%) samples and N. americanus in 278 (73.5%), of which 64 (16.9%), represented co-infections with both species. While A. duodenale was predominantly detected in the samples from Bolgatanga, infections in Garu related almost exclusively to N. americanus. The results showed that the present PCR approach is a valuable complementary tool for the diagnosis of A. duodenale infection in humans in Ghana, having implications for epidemiological studies and for the monitoring of the success of control programmes in regions in Africa.  (+info)

The development of endemic diseases such as worm infections that are transmitted through soil is strongly influenced by climatic conditions in tropical Indonesia. The worms included in the Soil Transmitted Helminth are Ascaris lumbricoides, Trichuris trichiura and Hookworm (Necator americanus and Ancylostoma duodenale). Ngagrong is a village in the highlands in Boyolali Regency. The majority of the population works as farmers, especially vegetable farmers. It is suspected that the habit of farmers while working who sometimes do not use personal protective equipment such as gloves and footwear in the form of sandals or shoes that directly contact with the soil and eat food without first washing their hands can give them a risk of worm infection.

I had heard about people using fecal transplants for certain disorders. In fact, I believe that theres a non-profit outside Boston that accepts stool donations which it passes on to those suffering from colitis. So I guess if someones willing to treat themselves with shit, its not a big leap to treatment with hookworms.. The need for all these new approaches to inflammatory diseases is because said diseases have proliferated. One hypothesis is that the proliferation has been brought out precisely because modernity - and folks like the Rockefeller Foundation who went through the South wiping out hookworm - has done too good a job. Weve sanitized ourselves to such an extent that we dont have enough of the microorganisms needed to keep us healthy. Anyway, it turns out that hookworms - necator americanus - are particularly ideal for helminth treatment. So, if youre suffering, you can order up some hookworms for Wormswell.

The relationship between iron status and the intensity of infection with hookworm was investigated in a rural population on Karkar Island, Mandang Province, Papua New Guinea. There was a significant negative correlation between plasma ferritin level and hookworm burden, which was strongest in males. In contrast, there was no correlation between plasma ferritin and hookworm egg count, and no consistent correlation between haemoglobin level or haematocrit and either measure of hookworm intensity. The results suggest that the role of hookworm in the aetiology of anaemia may be difficult to assess without the accurate measurement of hookworm burden.. ...

Newly eclosed workers of the frequently enslaved ant species Leptothorax longispinosus were either exposed to conspecific larvae, exposed to larvae of the slave-making parasite Harpagoxenus americanus, or reared in social isolation. In all conditions, the L. longispinosus workers later accepted H. americanus larvae preferentially. This finding indicates that H. americanus larvae are highly attractive to Leptothorax workers and demonstrates that early learning need not to be invoked to account for the acceptance of Harpagoxenus brood by enslaved Leptothorax workers.

Patent and pathologic infections of the human hookworm Necator americanus were established in the common marmoset (Callithrix jacchus). In a pilot study, a laboratory strain of N. americanus was compared with a fresh field isolate. Pathology was more severe in animals infected with a fresh isolate. In all animals, infection was associated with increased total plasma IgE and production of IgG specific to adult worm excretory/secretory (ES) products. Histamine was released by basophils in response to IgE, ES products, and a recombinant hookworm allergen, calreticulin. The pilot study indicated the potential of this animal model of hookworm infection and led us to investigate the consequences of infecting a further cohort with the fresh field isolate. This second study confirmed our initial findings, that it is possible to investigate the human hookworm N. americanus in a model exhibiting many of the characteristics of the immunology of hookworm infection in its definitive host.
Abstract Hookworms are enteric parasitic roundworms infecting an estimated 400 million persons worldwide. Herein, we provide the first molecular identifications of human hookworms from certain parts of rural Lower Myanmar. DNA was extracted from hookworm-positive stool samples, as determined by microscopy. DNA sequences of the partial internal transcribed spacer 1, full length 5.8S gene, and partial internal transcribed spacer 2 were determined and compared with available hookworm sequences from public databases. Of the 11 polymerase chain reaction-positive samples, eight (Bago Region, N = 4; Mon State, N = 4) yielded sequences with high similarity to those of Necator americanus. A further three sequences (Mon State, N = 2; Bago Region, N = 1) showed high similarity with those of Ancylostoma ceylanicum. The latter is primarily a parasite of dogs and represents a zoonosis. Given that different species of hookworms exhibit different epidemiological and biological characteristics, accurate identification

EDITORIAL. The multifactorial burden of anaemia in Africa Karen Sliwa*. Director: Soweto Cardiovascular Research Unit, University of the Witwatersrand, Johannesburg The causation of anaemia is multifactorial in developing countries and includes micronutrient deficiencies (e.g. iron, folate, vitamin B12), chronic worm infections (e.g. hookworm, trichuris, schistosomiasis), haemoglobinopathies, cancer and chronic non-communicable disease such as chronic kidney disease and heart failure.. Anaemia is a major cause of morbidity in malaria, HIV and tuberculosis and is an independent prognostic marker in HIV. It also contributes to the progression of HIV and tuberculosis.1 In Africa, anaemia is particularly common in individuals infected with soil-transmitted helminths or schistosomes. Blood loss in hookworm infections such as Necator americanus and Ankylostoma duodenale is strongly and linearly correlated with worm load and faecal egg count.2 Polyparasitism (infection with several parasites) is common ...

Hookworm infection contributes around 700 million infections worldwide especially in developing nations due to poor sanitation. The effective recovery of hookworm ova from wastewater matrices is difficult due to their low concentrations and heterogeneous distribution. In this study, we compared the recovery rates of (i) four rapid hookworm ova concentration methods from municipal wastewater, and (ii) two concentration methods from sludge samples. Ancylostoma caninum ova were used as surrogate for human hookworm (Ancylostoma duodenale and Necator americanus). Known concentration of A. caninum hookworm ova were seeded into wastewater (treated and raw) and sludge samples collected from two wastewater treatment plants (WWTPs) in Brisbane and Perth, Australia. The A. caninum ova were concentrated from treated and raw wastewater samples using centrifugation (Method A), hollow fiber ultrafiltration (HFUF) (Method B), filtration (Method C) and flotation (Method D) methods.

In northern Ghana and Togo, Oesophagostomum bifurcum infects an estimated 250,000 people, as determined by cultures of stool samples. The juvenile stages of the helminth develop within colonic wall nodules, causing Dapaong tumor or multinodular disease, at the rate of 1 case per week at Nalerigu Hospital in Ghana. Our aim was to discover whether suspected colonic-wall pathology is ultrasonographically visible in asymptomatic individuals living in the area where O. bifurcum is endemic. A total of 464 persons from 3 villages, ranging from highly infected to noninfected, were examined with ultrasonography. Anechogenic colonic lesions with posterior wall enhancement were observed in 71 (54.2%) of 131 and 57 (24.5%) of 233 persons from the villages of endemicity, and no lesions were seen in persons from the village outside the area of endemicity. We describe the lesions noted in this study as nodules caused by O. bifurcum, on the basis of their association at a population level with prevalence of ...
With an estimated 740 million individuals infected, hookworm is a major public health concern. While hookworm infection may not directly lead to mortality, its effects on morbidity demand immediate attention. When considering disability-adjusted life years (DALYs), neglected tropical diseases, including hookworm, rank among diarrheal diseases, ischemic heart disease, malaria, and tuberculosis as one of the most important health problems of the developing world.. It has been estimated that as many as 22.1 million DALYs have been lost due to hookworm. Recently, there has been increasing interest to address the public health concerns associated with hookworm. For example, the Bill & Melinda Gates Foundation recently donated US$34 million to fight Neglected Tropical Diseases including hookworm infection.[13] Former US President Clinton also announced a mega-commitment at the Clinton Global Initiative (CGI) 2008 Annual Meeting to de-worm 10 million children.[14].

We present evidence that the dog hookworm (Ancylostoma caninum) is underutilised in the study of host-parasite interactions, particularly as a proxy for the human-hookworm relationship. The inability to passage hookworms through all life stages in vitro means that adult stage hookworms have to be harvested from the gut of their definitive hosts for ex vivo research. This makes study of the human-hookworm interface difficult for technical and ethical reasons. The historical association of humans, dogs and hookworms presents a unique triad of positive evolutionary pressure to drive the A. caninum-canine interaction to reflect that of the human-hookworm relationship. Here we discuss A. caninum as a proxy for human hookworm infection and situate this hookworm model within the current research agenda, including the various omics applications and the search for next generation biologics to treat a plethora of human diseases. Historically, the dog hookworm has been well described on a physiological and

Computer illustration of the head of the parasitic hookworm Ancylostoma duodenale. This is one of the commonest causes of hookworm infestation in humans, particularly in sub-tropical regions such as North Africa and India. The worms head contains several tooth-like structures with which it clings to the bowel of its host. Hookworms also infect dogs and cats. Human infestation begins with larvae penetrating the skin, usually by burrowing into the feet of a person and entering the bloodstream. The larvae then migrate throughout the body, particularly the small intestine. - Stock Image F018/2182
A prime example of the kind of evidence at hand to establish transoceanic transport for such organisms is the case of the hookworm, Ancylostoma duodenale. Its relative rarity in some tropical areas of the New World and its long-term prevalence in East and Southeast Asia make the latter area the place where epidemiologists think the organism originated. At first early historians of medicine assumed that A. duodenale had been introduced into the Americas by slaves brought from Africa. Early in the 20th century, O. da Fonseca discovered the parasite in an isolated Amerindian population in the Amazon basin.49 Shortly afterward, microbiologist Samuel Darling weighed the evidence and concluded it was likely that the hookworm had reached native South American forest dwellers before Columbus arrived. If that could be proven, he observed, then the only plausible explanation for its presence in the New World would be that it arrived anciently via infected humans who had crossed the ocean.50. His ...

Objective-To determine interactions between Oesophagostomum spp and Salmonella ser. Typhimurium in pigs. Animals-30 healthy 5- to 6-week-old pigs. Procedure-Pigs were allotted to 3 groups (n = 10 pigs/group) and treated as follows: group A was given Oesophagostomum dentatum and 0 quadrispinulatum; group B was given 0 dentatum, 0 quadrispinulatum, and S Typhimurium; and group C was given STyphimurium only. Pigs in groups A and B were trickle infected with Oesophagostomum spp 3 times weekly throughout the study. After 19 days, groups B and C were inoculated once with STyphimurium. One pig from each group was euthanatized on the day of Salmonella exposure and 2 and 4 days after Salmonella exposure. The remaining pigs were euthanatized on days 16 and 17 after Salmonella exposure. Results-Pigs with dual infections of nematodes and bacteria (group B) excreted significantly higher amounts of S Typhimurium in feces, compared with nematode-free pigs (group C). In addition, group-B pigs excreted ...

Viability and in vitro and in vivo activities of freeze-dried conidia of the predatory fungus Arthrobotrys robusta (I-31) were evaluated against infective larvae (L3) of Ancylostoma spp. in dogs. A. robusta conidia were lyophilized and stored at 4 °C for a month. Freeze-dried conidia were diluted to 1 × 103 conidia/ml and tested in vivo. The treated group consisted of a solution containing conidia (1 ml) and 1000 Ancylostoma spp. (L3) placed on Petri dishes plated with 2% water-agar (2% WA), at 25 °C, in the dark for 10 days. The control group consisted of 1000 Ancylostoma spp. L3, plated on 2% WA. After 10 days, Ancylostoma spp. L3 from both the treated and the control groups were recovered and counted. The in vivo test was performed on two dogs by administering a single oral dose of freeze-dried conidia (1.5 × 105) in aqueous solution to one animal and only water to the other. Fecal samples were collected at 12, 24 and 48 h after the treatments, plated 2% WA plates and incubated at 25 °C ...

Hookworm parasite. Light micrograph of the rear end of Ancylostoma caninum, a parasitic hookworm which affects cats and dogs. This species of nematode worm is unable to mature in humans but the larvae often causes lesions in the skin. The hookworm larvae live in soil and water, mainly in the warm, moist tropics. They enter a host by boring through the skin. Once within the body they migrate, via the lungs, to the intestines. Here they secure themselves with hooks around their mouthparts to the intestinal wall and suck blood from their host. They release thousands of eggs each day which pass out of the host with the feces. Magnification: x18 at 35mm size. - Stock Image Z180/0013

... can also be caused by eating raw or undercooked meat from an animal that has the larvae of the tapeworm, grouped in cysts (coenuri) in its muscle tissue. Once ingested, the larvae then develop into adult tapeworms in the intestines. Adult tapeworms can measure up to 55 feet (17 m) long and can survive as long as 25 years. Some tapeworms attach themselves to the walls of the intestine, where they cause irritation or mild inflammation, while others may pass through to the stool and exit the body. Unlike other tapeworms, the dwarf tapeworm can complete its entire life cycle - egg to larva to adult tapeworm - in one host. This is the most common tapeworm infection in the world and can be transmitted between humans. Even while being treated for certain tapeworm infections, reinfection can result from ingesting tapeworm eggs shed by the adult worm into the stool, as a result of insufficient personal hygiene.. ...
As of 2009, loiasis is endemic to 11 countries, all in western or central Africa, and an estimated 12-13 million people have the disease. The highest incidence is seen in Cameroon, Republic of the Congo, Democratic Republic of Congo, Central African Republic, Nigeria, Gabon, and Equatorial Guinea. The rates of Loa loa infection are lower but it is still present in and Angola, Benin, Chad and Uganda. The disease was once endemic to the western African countries of Ghana, Guinea, Guinea Bissau, Ivory Coast and Mali but has since disappeared.[10]. Throughout Loa loa-endemic regions, infection rates vary from 9 to 70 percent of the population.[3] Areas at high risk of severe adverse reactions to mass treatment (with Ivermectin) are at present determined by the prevalence in a population of ,20% microfilaremia, which has been recently shown in eastern Cameroon (2007 study), for example, among other locales in the region.[10]. Endemicity is closely linked to the habitats of the two known human loiasis ...
The entire life cycle, from egg to adult, takes place in the human gastrointestinal tract of a single host,[18][19] from about 2-4 weeks[20] or about 4-8 weeks.[21] The life cycle begins with eggs being ingested.[19] The eggs hatch in the duodenum (i.e., first part of the small intestine).[22] The emerging pinworm larvae grow rapidly to a size of 140 to 150 μm,[20] and migrate through the small intestine towards the colon.[19] During this migration, they moult twice and become adults.[19][21] Females survive for 5 to 13 weeks, and males about 7 weeks.[19] The male and female pinworms mate in the ileum (i.e., last part of the small intestine),[19] whereafter the male pinworms usually die,[22] and are passed out with stool.[23] The gravid female pinworms settle in the ileum, caecum (i.e., beginning of the large intestine), appendix and ascending colon,[19] where they attach themselves to the mucosa[21] and ingest colonic contents.[24] Almost the entire body of a gravid female becomes filled with ...
Eggs are passed through the feces of an infected definitive host, usually a mammalian herbivore including rabbits, sheep, cattle, and rodents.[6] Under certain environmental conditions, which include optimal temperature and humidity, larvae hatch from eggs after several days. Hatched rhabditiform larvae grow on vegetation or within soil. After 5 to 10 days, two molts (L1 & L2) have occurred and the parasite becomes a filariform (L3) larvae that is infectious. Infection in mammals occurs upon ingestion of infective filariform (L3) larvae. The larvae reaches the small intestine to reside and mature into adult worms within their definitive hosts. Infections in humans may occur as incidental infections.[7] Trichostrongylus consists of multiple species that relate to each of its host, when it comes to parasitic survival and infection. For example, Trichostrongylus affinis primarily infects cottontail rats, Trichostrongylus sigmodontis affects hispid cotton rat, and marsh rice rat, and ...
Other countries followed the example of Pakistan, and by 2004, Guinea worm was eradicated in Asia. In December 2008, The Carter Center announced new financial support totaling $55 million from the Bill & Melinda Gates Foundation and the United Kingdom Department for International Development.[23] The funds will help address the higher cost of identifying and reporting the last cases of Guinea worm disease. Since the worm has a one-year incubation period, there is a very high cost of maintaining a broad and sensitive monitoring system and providing a rapid response when necessary.[23] One of the most significant challenges facing Guinea worm eradication has been the civil war in Southern Sudan, which was largely inaccessible to health workers due to violence.[9][24] To address some of the humanitarian needs in Southern Sudan, in 1995, the longest ceasefire in the history of the war, and the longest humanitarian cease-fire in history,[25] was achieved through negotiations by Jimmy Carter.[9][24] ...
Adult worms are found in nodules and are hidden from most components of the human immune system. Microfilariae are more vulnerable to attack by immune cells because they exit nodules to complete their lifecycle. O. volvulus can be detected by the immune system through the release of soluble antigens and antigens found on the surface of microfilariae and infective J3 juveniles. These antigens allow the immune system to detect the presence of a foreign organism in the body and trigger an immune response to clear infection.[22] The immune response involves raising antibodies (IgG, IgM and IgE type) that can react with soluble antigens released by Onchocerca volvulus.[23] Opsonising antibodies that tag cells for destruction are also found against the infective J3 stage and microfilariae, but there is not enough evidence at the moment to say whether this is protective.[24] The antigens of O. volvulus are highly complex and show cross-reactivity with several other filarial worms. Little evidence ...
Most nematode species are dioecious, with separate male and female individuals, though some, such as Caenorhabditis elegans, are androdioecious, consisting of hermaphrodites and rare males. Both sexes possess one or two tubular gonads. In males, the sperm are produced at the end of the gonad and migrate along its length as they mature. The testis opens into a relatively wide seminal vesicle and then during intercourse into a glandular and muscular ejaculatory duct associated with the vas deferens and cloaca. In females, the ovaries each open into an oviduct (in hermaphrodites, the eggs enter a spermatheca first) and then a glandular uterus. The uteri both open into a common vulva/vagina, usually located in the middle of the morphologically ventral surface.[39] Reproduction is usually sexual, though hermaphrodites are capable of self-fertilization. Males are usually smaller than females or hermaphrodites (often much smaller) and often have a characteristically bent or fan-shaped tail. During ...
Antibody detection can be useful to indicate schistosome infection in people who have traveled to areas where schistosomiasis is common and in whom eggs cannot be demonstrated in fecal or urine specimens. Test sensitivity and specificity vary widely among the many tests reported for the serologic diagnosis of schistosomiasis and are dependent on both the type of antigen preparations used (crude, purified, adult worm, egg, cercarial) and the test procedure.[32] At the U.S. Centers for Disease Control and Prevention, a combination of tests with purified adult worm antigens is used for antibody detection. All serum specimens are tested by FAST-ELISA using S. mansoni adult microsomal antigen. A positive reaction (greater than 9 units/µl serum) indicates infection with Schistosoma species. Sensitivity for S. mansoni infection is 99%, 95% for S. haematobium infection, and less than 50% for S. japonicum infection. Specificity of this assay for detecting schistosome infection is 99%. Because test ...

Toxoplasmosis is becoming a global health hazard as it infects 30-50% of the world human population. Clinically, the life-long presence of the parasite in tissues of a majority of infected individuals is usually considered asymptomatic. However, a number of studies show that this 'asymptomatic infection' may also lead to development of other human pathologies. ... The seroprevalence of toxoplasmosis correlated with various disease burden. Statistical associations does not necessarily mean causality. The precautionary principle suggests however that possible role of toxoplasmosis as a triggering factor responsible for development of several clinical entities deserves much more attention and financial support both in everyday medical practice and future clinical research ...
... is a tissue infection caused by the young form of the pork tapeworm.[6][1] People may have few or no symptoms for years.[3][2] In some cases, particularly in Asia, solid lumps of between one and two centimetres may develop under the skin.[1] After months or years these lumps can become painful and swollen and then resolve.[3][2] A specific form called neurocysticercosis, which affects the brain, can cause neurological symptoms.[2] In developing countries this is one of the most common causes of seizures.[2] Cysticercosis is usually acquired by eating food or drinking water contaminated by tapeworm eggs from human feces.[1] Among foods, uncooked vegetables are the major source.[1] The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis.[2][7] Taeniasis, in the strict sense, is a different disease and is due to eating cysts in poorly cooked pork.[1] People who live with someone with the pork tapeworm have a greater risk of ...
Eggs are deposited in feces of dogs, becoming infectious after 2-4 weeks.[7] Dogs ingest infectious eggs, allowing the eggs to hatch and the larval form of the parasite to penetrate through the gut wall. In dogs under 3 months of age, the larvae hatch in the small intestine, get into the bloodstream, migrate through the liver, and enter the lungs. Once in the lungs, the larvae crawl up the trachea. The larvae are then coughed up and swallowed, leading back down to the small intestine, where they mature to adulthood. This process is called tracheal migration. In dogs older than 3 months of age, the larvae hatch in the small intestine and enter the bloodstream, where they are carried to somatic sites throughout the body (muscles, kidney, mammary glands, etc.) where they become encysted second stage larvae. This process is called somatic migration. At the height of pregnancy, the encysted eggs in an infected female dog will migrate from the mother to the developing fetus, where they will reside in ...
S. mekongi shares many general characteristics with other schistosomes, particularly S. japonicum, but it does have crucial differences. S. mekongi eggs are 30-55 μm and have a diminutive spine, and only 95 per mating pair are produced per day, whereas S. japonicum eggs are larger and produce on average 250 per day. N. aperta infected release on 42 cercaria per day, far lower than other Schistosomes.[3] ...
Infection is acquired most commonly from eggs in the feces of another infected individual, which are transferred in food, by contamination. Eggs hatch in the duodenum, releasing oncospheres, which penetrate the mucosa and come to lie in lymph channels of the villi. An oncosphere develops into a cysticercoid which has a tail and a well-formed scolex. It is made of longitudinal fibers and is spade-shaped with the rest of the worm still inside the cyst. In five to six days, cysticercoids emerge into the lumen of the small intestine, where they attach and mature. The direct lifecycle is doubtless a recent modification of the ancestral two-host lifecycle found in other species of hymenolepidids, because cysticercoids of H. nana can still develop normally within larval fleas and beetles. One reason for facultative nature of the lifecycle is that H. nana cysticercoids can develop at higher temperatures than can those of the other hymenolepidids. Direct contaminative infection by eggs is probably the ...
The flatworms, flat worms, Platyhelminthes, Plathelminthes, or platyhelminths (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm")[2] are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously.. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be ...
True tapeworms are exclusively hermaphrodites, with both male and female reproductive systems in their bodies. The reproductive system includes one or more testes, cirri, vas deferens, and seminal vesicles as male organs, and a single lobed or unlobed ovary with the connecting oviduct and uterus as female organs. The common external opening for both male and female reproductive systems is known as the genital pore, which is situated at the surface opening of the cup-shaped atrium.[12][13] Though they are sexually hermaphroditic, self-fertilization is a rare phenomenon. To permit hybridization, cross-fertilization between two individuals is often practiced for reproduction. During copulation, the cirri of one individual connect with those of the other through the genital pore, and then spermatozoa are exchanged.. The lifecycle of tapeworms is simple in the sense that no asexual phases occur as in other flatworms, but complicated in that at least one intermediate host is required as well as the ...
