These results indicated that CE, RN and PB States presented a broader viral activity, in contrast with the viral circulation in the Midwest and Southern esstomatitis, whose immunological reaction probably reflects a low frequency and remote viral activity.
An enzyme-linked immunosorbent assay for the detection of vesicular stomatitis virus antigen. Eduardo Furtado Flores, email: Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian Vesivular. Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus.
High percentages of positive samples were estomatitsi in CE VSV naturally infects a variety of mammals including horses, cattle, swine, wild mammals and man. Transmission and pathogenesis of vesicular stomatitis virus. Southern, Midwestern and Northeast. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Then, positive samples were submitted to a quantitative VN test, in which a fixed dose of virus TCID 50 qeuina incubated with serial 2-fold dilutions of sera, starting at 1: Vesicular stomatitis in Brazil I – Isolation and identification of the Alagoas strain.
Brazilian Journal of Veterinary Pathology, v. The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region. VSV isolates belong to two antigenically distinct serogroups: Samples not presenting cpe were considered positive estomatutis VSV antibodies at the used dilution.
OIE Terrestrial Manual1 may.
Residual antibodies were detected, probably reflecting remote past exposure to the virus in RS. Serological relationships between different strains of vesicular stomatis virus. Vesicular stomatitis virus VSV is a viral agent belonging to the order Mononegaviralesfamily Rhabdoviridaegenus Vesiculovirus. Our results reinforce the sanitary importance of this infection, contributing for its understanding, notification and control.
Estomatitis vesicular equina pdf
In contrast, samples from RS had low titers, possibly due to a past remote exposure. Ecologic studies of vesicular stomatitis virus.
In most cases, the disease is self-limiting and the clinical course lasts vewicular two to three weeks REIS JR et al. Journal of Veterinary Diagnostic Information, v. Anais de microbiologia, v. 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.
Genetic and antigenic relationships of vesicular stomatitis viruses from South America. Journal of American Veterinary Medical Association, v. Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: After complement inactivation, serum samples were diluted 1: 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: Boletim del Centro Panamericano de Fiebre Aftosa, v.
Journal of Medical Entomology, v. Financial impact of the outbreak of vesicular stomatitis on vesicupar beef ranches in Colorado. 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.
Horses are especially susceptible to VSV and may serve as sentinels for virus circulation.
The overall rate of seropositivity was According to the ICTVthere besicular the least 20 additional serotypes to be characterizated. Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al. 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.
Estomatitis vesicular by Sharyn Monterrosa Barajas on Prezi
American Journal of Epidemiology, v. In Brazil, positive serology to VSV has been detected in several states and different animal species.
Journal of General Virology, v. Figure 1 presents the frequency and distribution of neutralizing titers by state. Because cattle is the 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. Archives of Virology, v. The cultures were monitored for citopathic effect cpe for 72h.
Viral diseases to be differentiated from foot-and-mouth disease. Unfortunately, we could not test the samples against VSV Cocal because we could not obtain a virus of this serotype.
