These results demonstrated a relatively recent circulation of VSIV-3 in northeastern Brazilian States, confirming clinical findings and demonstrating the sanitary importance of this infection.

Como citar este artigo. Serological relationships between different strains of vesicular stomatis virus. 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.

In this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al. Genetic and antigenic relationships of vesicular stomatitis viruses from South America. Unfortunately, estomatifis could not test the samples against VSV Cocal because we could not obtain a virus of this serotype.

Then, positive samples were submitted to a quantitative VN test, in which a fixed dose of virus TCID 50 was incubated with serial 2-fold dilutions of sera, starting at 1: After complement inactivation, serum samples were diluted 1: Ecologic studies of vesicular stomatitis virus. Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al.

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.

Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus. Journal of General Virology, v. Brazilian Journal of Veterinary Pathology, v. Epidemiologia de la stomatitis vesicular. 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: Development and evaluation of an enzime-linked immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus.

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. An enzyme-linked immunosorbent assay vesicualr the detection of vesicular stomatitis virus antigen.

Figure 1 presents the frequency and distribution of neutralizing titers by state. In Brazil, positive serology to VSV has been detected in several states and different animal species.

VSV naturally infects a variety of mammals including horses, cattle, swine, wild mammals and man. American Journal of Epidemiology, v.

Archives of Virology, v. The present study used 3, serum samples from horses of three Brazilian regions: 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 regions, whose immunological reaction probably reflects a low frequency and remote viral activity.

The cultures were monitored for citopathic effect cpe for 72h. VSV infection is considered endemic in Brazilian northeastern States, where is probably under notified. Southern, Midwestern and Northeast.

Residual antibodies were detected, probably reflecting remote past exposure to the virus in RS. Samples not presenting cpe were considered positive for VSV antibodies at the used dilution. The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region. Journal of Veterinary Diagnostic Information, v. VSV isolates belong to two antigenically distinct serogroups: Outbreaks estojatitis vesicular stomatitis Alagoas virus in horses and cattle in northeastern Brazil.

Eduardo Furtado Flores, email: After 72h, the cultures were monitored for cpe and the VN titers were considered as the reciprocal of the highest serum dilution capable to prevent cpe.
