Vesicular stomatitis virus VSV is the agent of a vesicular disease that affects many animal species and may be clinically confounded with foot-and-mouth disease in ruminant and swine. VS in clinically undistinguishable from foot-and-mouth disease FMDmaking critical its prompt differential diagnosis.
Anais de microbiologia, v. According to the ICTVthere are the least 20 additional serotypes to be characterizated.
Comparison of virus neutralisation and enzime-linked immunosorbent assay for the identification of antibodies against vesicular stomatitis Indiana 3 virus. Genetic and antigenic relationships of vesicular stomatitis viruses from South America.
In Brazil, positive serology to VSV has been detected in several states and different animal species. In contrast, samples from Estkmatitis had low titers, possibly due to a past remote exposure.
Estomatitis vesicular by Sharyn Monterrosa Barajas on Prezi
In agreement with the latter work, our data indicates that VSV is already circulating in these edtomatitis. Samples not presenting cpe were considered positive for VSV antibodies at the used dilution. The overall rate of seropositivity was In most cases, the disease is self-limiting and the clinical course lasts approximately two to three weeks REIS JR et al.
Because cattle is eqyina most important host species for VSV infection – which it can be confounded with FMD, leading to serious sanitary consequences – it would be interesting to investigate the presence and distribution of VSV antibodies in cattle of the studied regions.
Since no comercial VSV vaccines are available in Brazil SINDAN,positive serological response is obviously due to a previous exposure to the virus, reflecting different levels of virus circulation in the three regions. Residual antibodies were detected, probably reflecting remote past exposure to the virus in RS. Transmission and pathogenesis of vesicular stomatitis virus. Financial impact of the estomatitos of vesicular stomatitis on 16 beef ranches in Colorado.
The cultures were monitored for citopathic effect cpe for 72h. Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian States. Unfortunately, we could not test the samples against VSV Cocal because we could not obtain a virus of this serotype. VSV infection is considered endemic in Brazilian extomatitis States, where is probably estomaritis notified. Como citar este artigo. Vesiculaf present study used 3, serum samples from horses of three Brazilian regions: Ecologic studies of vesicular stomatitis virus.
Journal of Veterinary Diagnostic Information, v. Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: Brazilian Journal of Veterinary Pathology, v. Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al. Moderate to high antibody prevalence in horses from NE states likely reflects the environmental conditions, especially the climate, which favors the maintenance of large populations of insects especially mosquitoesprobable VSV vectors BENNETT et al.
After 72h, the cultures were monitored esromatitis cpe and the VN titers were considered as the reciprocal of the highest serum dilution capable to prevent cpe.

Considering the sanitary and economical importance of the disease, this study was designed to investigate circulation of VSV-3, through serology, in horses from three Brazilian regions: Estomatiris this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al. Journal of Medical Entomology, v. Vesicular stomatitis in Brazil I – Isolation and identification of the Alagoas strain.
VSV isolates belong to two antigenically distinct serogroups: American Journal of Epidemiology, v.
VSV naturally infects a variety of mammals including horses, cattle, swine, wild mammals and man. The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region. Journal of American Veterinary Medical Association, v. OIE Terrestrial Manual1 may. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Archives of Virology, v. Vesicular stomatitis VS usually presents a seasonal pattern, whose incidence is usually higher in summer or in rainy seasons MASON et al.
High percentages of positive samples were observed in CE Several samples from equnia Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. Serogroup VSIV contains three subtypes: Eduardo Furtado Flores, email:
