Vectors of Chikungunya virus in Senegal: current data and transmission cycles. (1/380)

Chikungunya fever is a viral disease transmitted to human beings by Aedes genus mosquitoes. From 1972 to 1986 in Kedougou, Senegal, 178 Chikungunya virus strains were isolated from gallery forest mosquitoes, with most of them isolated from Ae. furcifer-taylori (129 strains), Ae. luteocephalus (27 strains), and Ae. dalzieli (12 strains). The characteristics of the sylvatic transmission cycle are a circulation periodicity with silent intervals that last approximately three years. Few epidemics of this disease have been reported in Senegal. The most recent one occurred in 1996 in Kaffrine where two Chikungunya virus strains were isolated from Ae. aegypti. The retrospective analysis of viral isolates from mosquitoes, wild vertebrates, and humans allowed to us to characterize Chikungunya virus transmission cycles in Senegal and to compare them with those of yellow fever virus.  (+info)

Comparison of PanBio dengue duo enzyme-linked immunosorbent assay (ELISA) and MRL dengue fever virus immunoglobulin M capture ELISA for diagnosis of dengue virus infections in Southeast Asia. (2/380)

The performances of the MRL dengue fever virus immunoglobulin M (IgM) capture enzyme-linked immunosorbent assay (ELISA) and the PanBio Dengue Duo IgM capture and IgG capture ELISA were compared. Eighty sera from patients with dengue virus infections, 24 sera from patients with Japanese encephalitis (JE), and 78 sera from patients with nonflavivirus infections, such as malaria, typhoid, leptospirosis, and scrub typhus, were used. The MRL test showed superior sensitivity for dengue virus infections (94 versus 89%), while the PanBio test showed superior specificity for JE (79 versus 25%) and other infections (100 versus 91%). The PanBio ELISA showed better overall performance, as assessed by the sum of sensitivity and specificity (F value). When dengue virus and nonflavivirus infections were compared, F values of 189 and 185 were obtained for the PanBio and MRL tests, respectively, while when dengue virus infections and JE were compared, F values of 168 and 119 were obtained. The results obtained with individual sera in the PanBio and MRL IgM ELISAs showed good correlation, but this analysis revealed that the cutoff value of the MRL test was set well below that of the PanBio test. Comparing the sensitivity and specificity of the tests at different cutoff values (receiver-operator analysis) revealed that the MRL and PanBio IgM ELISAs performed similarly in distinguishing dengue virus from nonflavivirus infections, although the PanBio IgM ELISA showed significantly better distinction between dengue virus infections and JE. The implications of these findings for the laboratory diagnosis of dengue are discussed.  (+info)

Re-emergence of Chikungunya and O'nyong-nyong viruses: evidence for distinct geographical lineages and distant evolutionary relationships. (3/380)

Chikungunya (CHIK) virus is a member of the genus Alphavirus in the family TOGAVIRIDAE: Serologically, it is most closely related to o'nyong-nyong (ONN) virus and is a member of the Semliki Forest antigenic complex. CHIK virus is believed to be enzootic throughout much of Africa and historical evidence indicates that it spread to other parts of the world from this origin. Strains from Africa and Asia are reported to differ biologically, indicating that distinct lineages may exist. To examine the relatedness of CHIK and ONN viruses using genetic data, we conducted phylogenetic studies on isolates obtained throughout Africa and Southeast Asia. Analyses revealed that ONN virus is indeed distinct from CHIK viruses, and these viruses probably diverged thousands of years ago. Two distinct CHIK virus lineages were delineated, one containing all isolates from western Africa and the second comprising all southern and East African strains, as well as isolates from Asia. Phylogenetic trees corroborated historical evidence that CHIK virus originated in Africa and subsequently was introduced into Asia. Within the eastern Africa and southern Africa/Asia lineage, Asian strains grouped together in a genotype distinct from the African groups. These different geographical genotypes exhibit differences in their transmission cycles: in Asia, the virus appears to be maintained in an urban cycle with Aedes aegypti mosquito vectors, while CHIK virus transmission in Africa involves a sylvatic cycle, primarily with AE: furcifer and AE: africanus mosquitoes.  (+info)

Phase II safety and immunogenicity study of live chikungunya virus vaccine TSI-GSD-218. (4/380)

We conducted a phase II, randomized, double-blind, placebo-controlled, safety and immunogenicity study of a serially passaged, plaque-purified live chikungunya (CHIK) vaccine in 73 healthy adult volunteers. Fifty-nine volunteers were immunized one time subcutaneously with the CHIK vaccine and 14 were immunized with placebo (tissue culture fluid). Vaccinees were clinically evaluated intensively for one month, and had repeated blood draws for serological assays (50% plaque-reduction neutralization test) for one year. Except for transient arthralgia in five CHIK vaccinees, the number and severity of local and systemic reactions and abnormal laboratory tests after immunization were similar in CHIK vaccinees and placebo recipients. Fifty-seven (98%) of 58 evaluable CHIK vaccinees developed CHIK neutralizing antibody by day 28, and 85% of vaccinees remained seropositive at one year after immunization. No placebo recipients seroconverted. This promising live vaccine was safe, produced well-tolerated side effects, and was highly immunogenic.  (+info)

Complete nucleotide sequence of chikungunya virus and evidence for an internal polyadenylation site. (5/380)

In this study, the complete genomic sequence of chikungunya virus (CHIK; S27 African prototype) was determined and the presence of an internal polyadenylation [I-poly(A)] site was confirmed within the 3' non-translated region (NTR) of this strain. The complete genome was 11805 nucleotides in length, excluding the 5' cap nucleotide, an I-poly(A) tract and the 3' poly(A) tail. It comprised two long open reading frames that encoded the non-structural (2474 amino acids) and structural polyproteins (1244 amino acids). The genetic location of the non-structural and structural proteins was predicted by comparing the deduced amino acid sequences with the known cleavage sites of other alphaviruses, located at the C-terminal region of their virus-encoded proteins. In addition, predicted secondary structures were identified within the 5' NTR and repeated sequence elements (RSEs) within the 3' NTR. Amino acid sequence homologies, phylogenetic analysis of non-structural and structural proteins and characteristic RSEs revealed that although CHIK is closely related to o'nyong-nyong virus, it is in fact a distinct virus. The existence of I-poly(A) fragments with different lengths (e.g. 19, 36, 43, 91, 94 and 106 adenine nucleotides) at identical initiation positions for each clone strongly suggests that the polymerase of the alphaviruses has a capacity to create poly(A) by a template-dependant mechanism such as 'polymerase slippage', as has been reported for vesicular stomatitis virus.  (+info)

Effect of temperature stress on immature stages and susceptibility of Aedes aegypti mosquitoes to chikungunya virus. (6/380)

A high temperature stress of 44.5 degrees C for 10 minutes on the larval stages was found to affect the susceptibility of adult Aedes aegypti mosquitoes to chikungunya virus. At this temperature, the mortality of the mosquito larvae was found to be approximately 95%, whereas a temperature greater than 45 degrees C for 10 minutes was found to be lethal. A temperature tolerant (TT) strain was developed by exposing the larvae to a temperature of 44.5 degrees C for 10 minutes at every generation for five generations. This strain was established to determine whether increase in the susceptibility was due to any selection pressure of higher temperature or to the influence of other intrinsic factors such as expression of immunoresponsive (IR) genes. Other studies on these mosquito strains showed that when maintained at 28 +/- 1 degrees C, there was no difference in the larval duration and mortality in the immature stages, but the mean survival of female mosquitoes in the TT strain was 5-6 days longer. Conversely, when mosquitoes were maintained throughout at 37 degrees C the mean survival of the mosquitoes decreased drastically in both strains, but the mean survival of females in the TT strain was 5-6 days longer compared with the unstressed controls. This increases the probability of at least one more blood meal. Fecundity of the TT strain was found to be lower than that of the control mosquitoes. Data suggest that expression of certain IR genes was affected by the heat shock. Some of these genes were up-regulated and down-regulated, which may have affected the susceptibility of mosquitoes to the virus. Although there was some selection in the temperature-tolerant individuals in the TT strain, when stressed by heat they showed expression of IR genes in a pattern similar to that in the normal controls. It appears that an increase in temperature above the average temperature of an area might help increase the proportion of virus-susceptible mosquitoes in the population. Such an increase in temperature in an endemic area would not only enhance the selection of temperature-tolerant individuals in a population having more longevity, but would also affect both intrinsic and extrinsic factors by reducing the extrinsic incubation period and increasing susceptibility of mosquitoes to viruses due to affected expression of IR genes.  (+info)

Differential infectivities of o'nyong-nyong and chikungunya virus isolates in Anopheles gambiae and Aedes aegypti mosquitoes. (7/380)

O'nyong-nyong virus (ONNV) and chikungunya virus (CHIKV) are closely related alphaviruses that cause human disease in Africa and Asia. Like most alphaviruses, CHIKV is vectored by culicine mosquitoes. ONNV is considered unusual as it primarily infects anopheline mosquitoes; however, there are relatively few experimental data to support this. In this study, three strains of ONNV and one strain of CHIKV were evaluated in Anopheles gambiae and Aedes aegypti mosquitoes and in four cell lines. As predicted, CHIKV was not infectious to An. gambiae, and we observed strain-variability for ONNV with respect to the ability of the virus to infect An. gambiae and Ae. aegypti. The species specificity in vivo was reflected by in vitro experiments using culicine and anopheline-derived cell lines.  (+info)

Determinants of vector specificity of o'nyong nyong and chikungunya viruses in Anopheles and Aedes mosquitoes. (8/380)

The alphaviruses o'nyong nyong virus (ONNV) and chikungunya virus (CHIKV) provide a unique system to study the viral genes involved in vector specificity. ONNV infects both anopheline and culicine mosquitoes, whereas CHIKV infects only culicine mosquitoes. In this study, chimeric viruses were constructed that contained genes from both ONNV and CHIKV. These chimeras and previously described full-length infectious clones of ONNV and CHIKV were evaluated in Anopheles gambiae and Aedes aegypti mosquitoes. Virus derived from the infectious clones of ONNV and CHIKV retained the vector specificity of the parental viruses. All six of the chimeras were found to infect Ae. aegypti mosquitoes at high rates but only the chimera containing viral genes encoding all of the structural proteins of ONNV was able to infect An. gambiae mosquitoes. These data indicate that all of the viral structural proteins are necessary for ONNV to infect An. gambiae mosquitoes.  (+info)

Chikungunya fever is a pandemic disease caused by the mosquito-borne Chikungunya virus (CHIKV). E1 glycoprotein mediation of viral membrane fusion during CHIKV infection is a crucial step in the release of viral genome into the host cytoplasm for replication. How the E1 structure determines membrane fusion and whether other CHIKV structural proteins participate in E1 fusion activity remain largely unexplored. A bicistronic baculovirus expression system to produce recombinant baculoviruses for cell-based assay was used.

Mouse macrophage innate immune response to chikungunya virus infection | Virology Journal | Full Text  Mouse macrophage innate immune response to chikungunya virus infection | Virology Journal | Full Text
Infection with Chikungunya alphavirus (CHIKV) can cause severe arthralgia and chronic arthritis in humans with persistence of the virus in perivascular macrophages of the synovial membrane by mechanisms largely ill-characterized. We herein analysed the innate immune response (cytokine and programmed cell death) of RAW264.7 mouse macrophages following CHIKV infection. We found that the infection was restrained to a small percentage of cells and was not associated with a robust type I IFN innate immune response (IFN-α4 and ISG56). TNF-α, IL-6 and GM-CSF expression were upregulated while IFN-γ, IL-1α, IL-2, IL-4, IL-5, IL-10 or IL-17 expression could not be evidenced prior to and after CHIKV exposure. Although CHIKV is known to drive apoptosis in many cell types, we found no canonical signs of programmed cell death (cleaved caspase-3, -9) in infected RAW264.7 cells. These data argue for the capacity of CHIKV to infect and drive a specific innate immune response in RAW264.7 macrophage cell which seems

Author Summary Chikungunya virus (CHIKV) is transmitted by mosquito bites and causes a febrile disease that is often characterized by persistent joint pain. Until recently, CHIKV outbreaks were limited to tropical areas of Africa and Asia. However, since 2007, following a large CHIKV epidemic in the Indian Ocean and South-East Asia, CHIKV has also been reported in temperate European regions. As mosquito habitats expand, virus dissemination may become more prevalent, but there are currently no vaccines or CHIKV-specific treatments available. We previously described two human antibodies that potently block cellular CHIKV infection. In the current report, we have characterized CHIKV mutants that escape neutralization to identify sub-domains of the virus envelope which are involved in CHIKV interaction with these antibodies, thereby opening the door for the development of CHIKV-specific sub-domain vaccination strategies. For the first time, we have also demonstrated that CHIKV can be directly transmitted

The Cook Islands Ministry of Health has confirmed seven cases of chikungunya on Rarotonga since November 2014, in which three of the cases were considered locally acquired.. Local transmission means that mosquitoes in the area have been infected with chikungunya and are spreading it to people.. CDC recommends that travelers to the Cook Islands protect themselves from mosquito bites. Some travelers may be more likely to get chikungunya, have severe disease, or be at higher risk for other reasons. CDC advises travelers in high-risk groups to discuss their travel plans with their health care provider.. Chikungunya is a viral disease transmitted by the bite of infected mosquitoes such as Aedes aegypti and Aedes albopictus. It can cause high fever, join and muscle pain, and headache. Chikungunya does not often result in death, but the joint pain may last for months or years and may become a cause of chronic pain and disability..

Their newest investigation analyzed recent events in chikungunya virus evolution that will aid in predicting future trends in transmission and circulation that determine epidemic potential. Weaver and his team found that the initial adaption provided the framework for a second wave of adaptations that can enable rapid diversification of viral strains and even more efficient transmission to people. In addition, analysis of the chikungunya virus strain expressing a combination of the second-wave adaptive mutations revealed a similar pattern of changes and heightened adaptive qualities suggesting the future emergence of even higher transmission efficiency. ...

Abstract Five species of mosquito were studied to compare their susceptibility to infection, ability to sustain infection, and vector efficiency over a 4- to 5-week period after being infected with an African strain of chikungunya virus. Aedes triseriatus and Aedes albopictus were readily infected with the virus and maintained the highest infection and transmission rates of the mosquitoes tested during the test period. Aedes togoi also maintained a very high infection rate, but was a poor transmitter. Eretmapodites chrysogaster exhibited fairly high infection rates throughout the test and relatively high transmission rates in the latter half of the 35-day test period. Surprisingly low infection and transmission rates were found for Aedes aegypti.

Infection of Aedes albopictus with chikungunya virus rectally administered by enema  Infection of Aedes albopictus with chikungunya virus rectally administered by enema
Chikungunya virus (CHIKV) is an alphavirus transmitted by Aedes albopictus and Aedes aegypti mosquitoes in tropical areas of Africa, Asia, and the islands of the Indian Ocean. In 2007 and 2009, CHIKV was transmitted outside these tropical areas and caused geographically localized infections in people in Italy and France. To temporally and spatially characterize CHIKV infection of Ae. albopictus midguts, a comparison of viral distribution in mosquitoes infected per os or by enema was conducted. Ae. albopictus infected with CHIKV LR 5′ green fluorescent protein (GFP) at a titer 10[superscript 6.95] tissue culture infective dose[subscript 50] (TCID[subscript 50])/mL, were collected and analyzed for virus dissemination by visualizing GFP expression and titration up to 14 days post inoculation (dpi). Additionally, midguts were dissected from the mosquitoes and imaged by fluorescence microscopy for comparison of midgut infection patterns between orally- and enema-infected mosquitoes. When virus was ...

Diagnostic Options and Challenges for Dengue and Chikungunya Viruses  Diagnostic Options and Challenges for Dengue and Chikungunya Viruses
Dengue virus (DENV) and Chikungunya virus (CHIKV) are arboviruses that share the same |i|Aedes|/i| mosquito vectors and thus overlap in their endemic areas. These two viruses also cause similar clinical presentations, especially in the initial stages of infection, with neither virus possessing any specific distinguishing clinical features. Because the outcomes and management strategies for these two viruses are vastly different, early and accurate diagnosis is imperative. Diagnosis is also important for surveillance, outbreak control, and research related to vaccine and drug development. Available diagnostic tests are aimed at detection of the virus, its antigenic components, or the host immune antibody response. In this review, we describe the recent progress and continued challenges related to the diagnosis of DENV and CHIKV infections.

Florida case is unusual. Hirschwerk said he and his colleagues diagnosed chikungunya fever virus within the past six weeks. The Long Island patients were unrelated, he said.. "One of those cases has been confirmed by the CDC," Hirschwerk said, "and testing is still pending on the others..

Simple Clinical and Laboratory Predictors of Chikungunya versus Dengue Infections in Adults  Simple Clinical and Laboratory Predictors of Chikungunya versus Dengue Infections in Adults
Author Summary Dengue and chikungunya are mosquito-borne diseases that are found in similar geographical areas and present with similar symptoms. As their treatment is different, especially for dengue haemorraghic fever (DHF) which is a more severe form of dengue, it is important for healthcare workers to differentiate between them. We studied 117 chikungunya and 917 dengue adult patients (including 55 with DHF) by comparing their clinical presentation and developed decision trees to classify them using simple symptoms and laboratory tests. From the study, we found that at their first appearance in hospital, more chikungunya patients had muscle or joint pains, and fewer had a sore throat, cough, nausea, vomiting, diarrhea, stomach pain, loss of appetite or fast heart beat than DF or DHF patients. From the decision trees, of DF versus chikungunya using only platelet level cut-offs, we could correctly classify 89% of the cases. For DHF versus chikungunya using platelet level cut-offs and the presence of

Mosquito-borne chikungunya virus (CHIKV) is a positive-sense, single-stranded RNA virus from the genus Alphavirus, family Togaviridae, which causes fever, rash and severe persistent polyarthralgia in humans. Since there are currently no FDA licensed vaccines or antiviral therapies for CHIKV, the development of vaccine candidates is of critical importance. Historically, live-attenuated vaccines (LAVs) for protection against arthropod-borne viruses have been created by blind cell culture passage leading to attenuation of disease, while maintaining immunogenicity. Attenuation may occur via multiple mechanisms. However, all examined arbovirus LAVs have in common the acquisition of positively charged amino acid substitutions in cell-surface attachment proteins that render virus infection partially dependent upon heparan sulfate (HS), a ubiquitously expressed sulfated polysaccharide, and appear to attenuate by retarding dissemination of virus particles in vivo. We previously reported that, like other ...

Chikungunya virus (CHIKV) is an arthropod-borne agent that causes severe arthritic disease in humans and is considered a serious health threat in areas where competent mosquito vectors are prevalent. CHIKV has recently been responsible for several millions of cases of disease, involving over 40 countries. The recent re-emergence of CHIKV and its potential threat to human health has stimulated interest in better understanding of the biology and pathogenesis of the virus, and requirement for improved treatment, prevention and control measures. In this study, we mapped the binding sites of a panel of eleven monoclonal antibodies (mAbs) previously generated towards the capsid protein (CP) of CHIKV. Using N- and C-terminally truncated recombinant forms of the CHIKV CP, two putative binding regions, between residues 1-35 and 140-210, were identified. Competitive binding also revealed that five of the CP-specific mAbs recognized a series of overlapping epitopes in the latter domain. We also identified a

Identification of chikungunya virus nsP2 protease inhibitors using str by Phuong Nguyen, Haibo Yu et al.  "Identification of chikungunya virus nsP2 protease inhibitors using str" by Phuong Nguyen, Haibo Yu et al.
The nsP2 protease of chikungunya virus (CHIKV) is one of the essential components of viral replication and it plays a crucial role in the cleavage of polyprotein precursors for the viral replication process. Therefore, it is gaining attention as a potential drug design target against CHIKV. Based on the recently determined crystal structure of the nsP2 protease of CHIKV, this study identified potential inhibitors of the virus using structure-based approaches with a combination of molecular docking, virtual screening and molecular dynamics (MD) simulations. The top hit compounds from database searching, using the NCI Diversity Set II, with targeting at five potential binding sites of the nsP2 protease, were identified by blind dockings and focused dockings. These complexes were then subjected to MD simulations to investigate the stability and flexibility of the complexes and to gain a more detailed insight into the interactions between the compounds and the enzyme.

Chikungunya Virus Vaccine Trial in Healthy Adults - Tabular View - ClinicalTrials.gov  Chikungunya Virus Vaccine Trial in Healthy Adults - Tabular View - ClinicalTrials.gov
This is a Phase I, open-label, dose-escalation study to examine the safety, tolerability, and immune response to a Virus-Like Particle (VLP) Chikungunya Virus (CHIKV) vaccine in healthy adults ages 18 to 50 years old. The plan is for 25 subjects to receive 3 intramuscular vaccine injections at weeks 0, 4, and 20. The three groups will be enrolled sequentially starting with the lowest dose of 10 micrograms per injection in Group 1.. The hypothesis is that the vaccine is safe and induces immune responses to CHIKV. The primary objective is to evaluate the safety and tolerability of the investigational vaccine, VRC-CHKVLP059-00-VP, at three dosages, 10 micrograms (mcg), 20 mcg, and 40 mcg, in healthy adults. The secondary objective is to evaluate the antibody response against CHIKV VLPs four weeks after the third vaccine injection. The exploratory objectives relate to antigen-specific humoral and cellular immune responses throughout the study. ...

Abstract. Chikungunya virus (CHIKV) is an emerging, mosquito-borne alphavirus that has caused major epidemics in Africa and Asia. We developed chimeric vaccine candidates using the non-structural protein genes of either Venezuelan equine encephalitis virus (VEEV) attenuated vaccine strain TC-83 or a naturally attenuated strain of eastern equine encephalitis virus (EEEV) and the structural genes of CHIKV. Because the transmission of genetically modified live vaccine strains is undesirable because of the potentially unpredictable evolution of these viruses as well as the potential for reversion, we evaluated the ability of these vaccines to infect the urban CHIKV vectors, Aedes aegypti and Ae. albopictus. Both vaccine candidates exhibited significantly lower infection and dissemination rates compared with the parent alphaviruses. Intrathoracic inoculations indicated that reduced infectivity was mediated by midgut infection barriers in both species. These results indicate a low potential for transmission

Retrospective survey of Chikungunya disease among Réunion Island hospital staff  Retrospective survey of Chikungunya disease among Réunion Island hospital staff
Réunion Island (Indian Ocean) has been suffering from its first known Chikungunya virus (CHIKV) epidemic since February 2005. To achieve a better understanding of the disease, a questionnaire was drawn up for hospital staff members and their household. CHIKV infected about one-third of the studied population, the proportion increasing with age and being higher in women. Presence of a garden was associated with CHIKV infection. The geographical distribution of cases was concordant with insect vector Aedes albopictus distribution. The main clinical signs were arthralgia and fever. The disease evolved towards full recovery in 34·4% of cases, a relapse in 55·6%, or a chronic form in 10%. Paracetamol was used as a painkiller in 95% of cases, sometimes associated with non-steroidal anti-inflammatory drugs, corticoids, or traditional herbal medicine. The survey provided valuable information on the factors that favour transmission, the clinical signs, the importance of relapses and the therapies used.

2016 Chikungunya Virus Cases  2016 Chikungunya Virus Cases
After the bite of an infected mosquito, onset of illness occurs usually between 4 and 8 days, but can range from 2 to 12 days. Chikungunya is characterized by an abrupt onset of fever frequently accompanied by joint pain. Other common signs and symptoms include muscle pain, headache, nausea, fatigue and rash. The joint pain is often very debilitating, but usually lasts for a few days or may be prolonged to weeks. Hence the virus can cause acute, subacute, or chronic disease. Most patients recover fully, but in some cases joint pain may persist for several months, or even years. Occasional cases of eye, neurological, and heart complications have been reported, as well as gastrointestinal complaints. Serious complications are not common, but in older people, the disease can contribute to the cause of death. Often symptoms in infected individuals are mild and the infection may go unrecognized, or be misdiagnosed in areas where dengue occurs. Co-infections of dengue and chikungunya can occur ...

JCI - Chikungunya virus replication in skeletal muscle cells is required for disease development  JCI - Chikungunya virus replication in skeletal muscle cells is required for disease development
Chikungunya virus (CHIKV) is an arbovirus capable of causing a severe and often debilitating rheumatic syndrome in humans. CHIKV replicates in a wide variety of cell types in mammals, which has made attributing pathologic outcomes to replication at specific sites difficult. To assess the contribution of CHIKV replication in skeletal muscle cells to pathogenesis, we engineered a CHIKV strain exhibiting restricted replication in these cells via incorporation of target sequences for skeletal muscle cell-specific miR-206. This virus, which we term SKE, displayed diminished replication in skeletal muscle cells in a mouse model of CHIKV disease. Mice infected with SKE developed less severe disease signs, including diminished swelling in the inoculated foot and less necrosis and inflammation in the interosseous muscles. SKE infection was associated with diminished infiltration of T cells into the interosseous muscle as well as decreased production of Il1b, Il6, Ip10, and Tnfa transcripts. Importantly, ...

Chikungunya: Facts - Centre of Medical Knowledge Excellence  Chikungunya: Facts - Centre of Medical Knowledge Excellence
Chikungunya: Virus Chikungunya is a mosquito-borne alpha virus that was first isolated after a 1952 outbreak in modern-day Tanzania .A number of chikungunya outbreaks is due to the change in the genetic sequence which altered the viral coat protein which allows it to multiply more easily in the mosquito cells. The virus uses Asian tiger mosquito (invasive vector ) and the main vector being Aedes aegypti. Precautions need to be taken to stop the growth of the vector to combat the virus spread.. In 2006 there was a large outbreak in India . The virus re-emerged in 2006 after a gap of 32 years and caused an explosive outbreak affecting 13 states. The states first affected were Andhra Pradesh, Karnataka, Maharashtra, Madhya Pradesh, Tamil Nadu, Gujarat and Kerala. The tropical environment of India aids in the mosquito growth and hence spread of the virus.. Now in the year 2016 the outbreak in Delhi and regions near to Delhi is large. According to the Department of Microbiology at AIIMS, 712 samples ...

The genus Alphavirus is one of two within the family Togaviridae and comprises approximately 30 species, including several pathogens of humans and other animals that are of medical, veterinary and economic importance. Most alphaviruses are maintained in nature by a biological transmission cycle between susceptible vertebrate hosts and blood-feeding arthropods such as mosquitoes. In common with many Old World alphavirus pathogens Chikungunya virus (CHIKV) is the aetiological agent of a syndrome characterized by fever, skin rash and acute or chronic poly-arthralgia or arthritis. Whereas previously CHIKV outbreaks were sporadic and self-limiting, in 2004 it re-emerged in coastal Kenya and there followed a series of outbreaks that have continued until the present day, resulting in many millions of cases. Inroads into understanding the pathogenesis of CHIKV disease were until recently hampered through the lack of a convenient small animal model capable of exhibiting symptoms similar to those observed ...

Chikungunya comes from the Swahili language based on patient symptoms, which means (body position) bend or curve (that which contorts or bends up), referring to the bent posture of patients due to a great joint pain (arthralgia). This joint pain by safety data sheets (MSDS) Office of Laboratory Safety Canada, mainly occurs in the knees, ankles and joints, hands and feet. Apart from dengue fever cases are rampant in some parts of Indonesia, the community is also troubled by cases of Chikungunya. These symptoms include sudden fever that reached 39 degrees C, pain in the joints especially the knee joints, ankles, toes and hands and spine, accompanied by a rash (a collection of red dots) on the skin.

But, it is extremely painful. Dr. Jennifer Halverson, a Minnesota pediatrician who had been working in Haiti, was unlucky enough to contract Chikungunya in April of this year. "Ive broken a bone. Ive had other medical issues." she said. "I dont think Ive ever been in so much pain.". Fortunately, in the US we are not as susceptible to the epidemic spread that some countries are. In fact, Dr. Schaffner said, "I think its difficult to establish itself in the United States because were more separate from the mosquitoes than in the Caribbean. We live in an air conditioning environment and sit on porches - but they are screened… There might be bursts of transmission, but its not very easy to establish in the United States.". Still, we are advised to go ahead and take normal mosquito precautions like draining bird baths, dumping buckets, and getting rid of any other standing water around your property. Stay healthy!.

Serious international concern continues to exist around the Zika epidemic. The concern has arisen from two possible complications of Zika infection. Permanent fetal brain injury which results in severe microcephaly in some babies and a number of adults developing the neurological disease - Guillain-Barre syndrome, which causes paralysis. There is increasing evidence to indicate that Zika virus can be passed on by transfusion. Blood Services internationally have therefore taken steps to prevent this occurring.. Zika virus is spread by mosquitoes that have acquired the virus from another person who is infected with the virus. Zika virus is spreading in countries where dengue, chikungunya and other mosquito-borne infections are known to occur. Zika infection has many features similar to dengue and chikungunya infections.

Combating A Mosquito-Borne Disease. Last week, the World Health Organization reported confirmation of the spread of Chikungunya Virus in the southeastern part of the nation. Physicians verified four cases of the tropical disease in the Provence-Alpes-Cote dAzur region. Authorities also revealed the presence of a number of suspected cases of the illness. The patients ranged in age from 3 to 77. They apparently contracted the illness in France after sustaining bites from Aedes albopictus mosquitoes, a species sometimes referred to as the "tiger mosquito" because of its striped body. All of the people who contracted the febrile disease lived in the same region of France. Some people who contract Chikungunya Virus never display overt symptoms of the disease, a factor which may contribute to the spread of virus. Most patients do develop some signs of illness, which may include high fevers and joint pain, skin rashes and headaches.. A Growing Lyme Disease Threat in France. Earlier this summer, health ...

Invasion of the CNS is a key event during many viral infections and often a matter of life or death for the host. It is, however, difficult to follow this phenomenon in mammals, hindering the design of preventive strategies.. In the present work, we used zebrafish to characterize the infection course of SINV, a well-established model for the study of viral encephalitis. We focused on its neuroinvasion and compared it with that of CHIKV. This was studied following IV injections, which mimic the natural entry route of these mosquito-transmitted viruses, even though it results in more inter-individual variability than direct IC inoculation. We found that, upon IV inoculation of SINV, infected cells appeared in the periphery as early as 8 hpi, always before infected neurons of the CNS. Infection spontaneously declined in the periphery, probably as a result of the host response. Indeed, qRT-PCR analysis of whole larvae revealed strong induction of type I interferon (IFN) and IFN-stimulated genes of ...

Chikungunya (CHIK-un-goon-ya) virus (also known as CHIKV) is a mosquito-transmitted alphavirus that has spread around the world and is currently infecting people in about 60 countries globally. CHIKV is rarely fatal, but causes severe joint pain for months to years that can debilitate affected patients for long periods of time. There are currently no known drugs to treat CHIKV infection, primarily due to a lack of understanding of the structure of CHIKV proteins involved in viral genome replication. The Geiss lab has worked on developing drug targeting the membrane bound CHIKV nsP1 protein, which is the anchor for the viral genome replication complex on cellular membranes and a multifunctional enzyme that forms a 5 RNA cap structure on the end of the CHIKV RNA genome. Solving the structure of the CHIKV nsP1 protein would provide critical information for designing drugs that inhibit nsP1 function and abort viral genome replication ...

To characterize the immunity developed by patients infected by chikungunya virus (CHIKV), we studied the intensity and specificity of CHIKV-specific T cells mediated responses in chronic and recovered patients at 12 to 24 months post-infection. T cells were challenged in vitro against CHIKV synthetic peptides covering the length of three viral proteins, capsid, E2 and nsP1 proteins as well as all inactivated virus particles. Cytokine production was assessed by ELISPOT and intracellular labeling. T cells producing IFN-γ were detected against CHIKV in 85% patients cells either by direct ELISPOT assay (69% of patients) or after expansion of memory T cells allowing the detection of both CD4 and CD8 specific-T cells in 16% additional cases. The IFN-γ response was mainly engaged in response to nsP1 or E2 (52% and 46% cases, respectively) but in only 27% cases against the capsid. The anti-E2 response represented half the magnitude of the total CHIKV IFN-γ production and was mainly directed against the C

Many cases have occurred in the United States in people who acquired the virus while traveling, but the first locally transmitted case in the U.S. occurred in Florida in July.. The study showed that the rate of brain infection, or encephalitis, from the chikungunya virus is higher than the rate seen in the United States due to West Nile virus and similar infections between 1999 and 2007. Outbreaks of chikungunya have occurred in numerous areas, including Africa, Asia, the Caribbean islands, and as of September 2015 more than 7,000 cases have been reported in Mexico, according to the Centers for Disease Control and Prevention.. The most common symptoms of the infection are fever and joint pain. Most people recover within a week. For some people, the joint pain can continue for months and even years. "Since there is no vaccine to prevent chikungunya and no medicine to treat it, people who are traveling to these areas should be aware of this infection and take steps to avoid mosquito bites, such as ...

TIBBS » Stay Free of CHIKV!  TIBBS » Stay Free of CHIKV!
Chikungunya (pronunciation: chik-en-gun-ye), a virus with a difficult name to pronounce, is also proving difficult to contain. Like the more commonly known dengue virus, chikungunya (CHIKV) is an arbovirus, where "arbo" stands for "ARthropod-BOrne." Arthropod vectors most commonly include ticks and mosquitoes. The prevalence of mosquito hosts around the world, as well as travelers infected with exotic arboviruses, make tackling the spread of CHIKV tricky.. CHIKV spreads through two species of mosquito, Aedes albopictus and Aedes aegypti, which bite mostly during the daytime. Both are found in the southeastern and some parts of the southwestern United States. Aedes albopictus is also found in the Mid-Atlantic and lower Midwest. Animal reservoirs, which harbor CHIKV without developing the disease, include monkeys, birds, cattle, and rodents.. The most common symptoms of CHIKV virus infection are fever and joint pain, which appear 4 - 7 days post-infection. Other symptoms may include headache, ...

A new study in PLoS Neglected Tropical Diseases shows that the Aedes aegypti mosquito can transmit both Zika and chikungunya virus in one bite, and co-infection with the viruses does not alter vector competence.. Dutch scientists infected the insects with both viruses to determine transmission rates using an experimental blood meal and found that 73% of the mosquitoes transmitted Zika, 21% spread chikungunya, and 12% transmitted both viruses in one bite. This is the first study to show that, just as in humans, the viruses can commonly co-infect mosquitoes.. "We show that ZIKV and CHIKV can simultaneously disseminate to the saliva of Ae. aegypti mosquitoes, indicating that co-infections do not strongly interfere with virus replication," the authors write.. In other Zika news, a vaccine presented at the American Society of Microbiology (ASM) Microbe 2017 meeting that wrapped up today showed 100% protection from the virus in mouse models. The vaccine is the first to be based on the NS1 protein, and ...

The understanding of the current chikungunya burden depends on a better understanding of the mortality associated with this arboviruses. Our findings show excess mortality during chikungunya epidemics in three most affected states in Brazil. The correlation between the incidence of chikungunya and increase in all-cause mortality reinforce the possibility that chikungunya virus has an impact on mortality rates. Similar results have already been found in other chikungunya epidemics in the past decades2,3,4. Incidence of dengue virus was high in all studied areas in the years 2011-2013, used as a baseline5. Therefore, we suggest that the excess deaths should be related to chikungunya infections and not another arbovirus that occurs at the same season. This is the first time that the excess mortality associated with chikungunya by age group has been calculated, and the results are very close to that found in the Reunion Islands epidemic using the data obtained in the death certificates16.. Since the ...

To the Editor: Zika virus (ZIKV) is a mosquito-borne flavivirus related to yellow fever virus, dengue virus (DENV), and West Nile virus (WNV). It is a single-stranded positive RNA virus (10,794-nt genome) that is closely related to the Spondweni virus and is transmitted by many Aedes spp. mosquitoes, including Ae. africanus, Ae. luteocephalus, Ae. hensilli, and Ae. aegypti. The virus was identified in rhesus monkeys during sylvatic yellow fever surveillance in the Zika Forest in Uganda in 1947 and was reported in humans in 1952 (1).. In 2007, an outbreak of ZIKV was reported in Yap Island, Federated States of Micronesia (2). ZIKV also caused a major epidemic in the French Polynesia in 2013-2014 (3), and New Caledonia reported imported cases from French Polynesia in 2013 and reported an outbreak in 2014 (4).. A new challenge has arisen in Brazil with the emergence of ZIKV and co-circulation with others arboviruses (i.e., DENV and chikungunya virus [CHIKV]). We report ZIKV infection in Brazil ...

Arthropod-borne viruses (arboviruses) can persistently infect and cause limited damage to mosquito vectors. RNA interference (RNAi) is a mosquito antiviral response important in restricting RNA virus replication and has been shown to be active against some arboviruses. The goal of this study was to use a recombinant Sindbis virus (SINV; family Togaviridae; genus Alphavirus) that expresses B2 protein of Flock House virus (FHV; family Nodaviridae; genus Alphanodavirus), a protein that inhibits RNAi, to determine the effects of linking arbovirus infection with RNAi inhibition. B2 protein expression from SINV (TE/32J) inhibited the accumulation of non-specific small RNAs in Aedes aegypti mosquito cell culture and virus-specific small RNAs both in infected cell culture and Ae. aegypti mosquitoes. More viral genomic and subgenomic RNA accumulated in cells and mosquitoes infected with TE/32J virus expressing B2 (TE/32J/B2) compared to TE/32J and TE/32J virus expressing GFP. TE/32J/B2 exhibited increased

Salmonella contamination of 71 chicken broiler flocks was investigated at the slaughterhouse in Reunion Island between October 2007 and January 2009. Samples were collected from live broiler chickens and chicken carcasses as well as the slaughterhouse environment. Salmonella spp. was isolated from 40 of 71 (56 % with a confidence interval 5 % [45-67]) broiler chicken flocks at slaughter. The most prominent serovars were Blockley (31 %), Typhimurium and Brancaster (14 %), Hadar (10 %), Salmonella multidrug resistant clinical organisms serotypes 1,4,[5],12:i:-, and Virchow (8 %) and Livingstone, St. Paul, Seftenberg, Llandoff, Infantis and Indiana. At the farm, 27 % of the broiler chicken flocks tested positive for Salmonella spp. Salmonella spp. was isolated from 124 of 497 environmental samples (25 %). In most cases, there was no relationship between pulsed field gel electrophoresis (PFGE) pattern and antibiotic resistance pattern. The predominant Salmonella serovars were susceptible to most of the

The Cuyahoga County Board of Health continues to work closely with the Ohio Department of Health and conducts surveillance to monitor for mosquitoes that may transmit disease, including the Zika virus. Although local transmission of Zika virus through the bite of a mosquito has not been identified in the continental United States, the U.S. mainland does have two species of mosquitoes that can become infected with and spread Zika virus. The primary vector for transmitting Zika, the Aedes aegypti mosquito, is not established in Ohio and is found in the Southeastern States. A possible second vector, the Aedes albopictus mosquito, is also known as the Asian Tiger mosquito and is rarely found in Northeast Ohio. These species of mosquitoes do not breed in storm water control basins or woodland pools. They prefer to breed in water that collects in artificial containers (tires, buckets, garbage cans, flower pots, childrens toys, etc.).
