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: Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus.
Because cattle is the most important host species estomaittis 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.
Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. Vesjcular isolates belong to two antigenically distinct serogroups: Anais de microbiologia, v. Boletim del Centro Panamericano de Fiebre Aftosa, v. The present study used 3, serum samples from horses of three Brazilian regions: According to the ICTVthere are the least 20 additional serotypes to be characterizated.
Archives of Virology, v. In this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al.
Vesicular stomatitis in Brazil I – Isolation and identification of the Alagoas strain. 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. In most cases, the disease is self-limiting and the clinical course lasts approximately two to three weeks REIS JR et al.
Comparison of virus neutralisation and enzime-linked immunosorbent assay for the identification of antibodies against vesicular stomatitis Indiana 3 virus. fesicular
Unfortunately, we could not test the samples against VSV Cocal because we could not obtain a virus of this serotype. The overall rate of seropositivity was Samples not presenting cpe were considered positive for VSV antibodies at the used dilution. 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. Climatic and geographic influences on arboviral infections and vectors.
Transmission and pathogenesis 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 for the detection of vesicular stomatitis virus antigen. Outbreaks of vesicular stomatitis Alagoas virus in horses and cattle in northeastern Brazil. After complement inactivation, serum samples were diluted 1: In Brazil, positive serology to VSV has been detected in several states and different animal species. Epidemiologia de la stomatitis vesicular.

Vesicular stomatitis VS usually presents a seasonal pattern, whose incidence is usually higher in summer or in rainy seasons MASON et al. Genetic and antigenic relationships of vesicular stomatitis viruses from South America. Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al. Serogroup VSIV contains qeuina subtypes: Journal of Medical Entomology, v.
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: The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region.

In contrast, samples from RS had low titers, possibly due to a past remote exposure. Serological relationships between different strains of vesicular stomatis virus.
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. Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: Eduardo Furtado Flores, email: Development and evaluation of an enzime-linked immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus.
Brazilian Journal of Veterinary Pathology, v. Our results reinforce the sanitary importance of this infection, contributing for its understanding, notification and control. VS in clinically undistinguishable from foot-and-mouth disease FMDmaking critical its prompt differential diagnosis. 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. VSV infection is considered endemic in Brazilian northeastern States, where is probably under notified.
Figure 1 presents the frequency and distribution of neutralizing titers by state. The cultures were monitored for citopathic effect cpe for 72h. In agreement with the latter work, our data indicates that VSV is already circulating in these regions. OIE Terrestrial Manual1 may.
