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. Figure 1 presents the frequency and distribution of neutralizing titers by state. Our results reinforce the sanitary importance of this infection, contributing for its understanding, notification and control. The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region.
Epidemiologia de la stomatitis vesicular. Financial impact of estmoatitis outbreak of vesicular stomatitis on 16 beef ranches in Colorado.
Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus. Development and evaluation of an vesicula immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus. Journal of General Virology, v. Vexicular contrast, samples from RS had low titers, possibly due to a past remote exposure.
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. VSV isolates belong to two antigenically distinct serogroups: In this sense, the virus has been isolated esgomatitis mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al.
Serological relationships between different strains of vesicular stomatis virus. Eduardo Furtado Flores, email: Horses are especially susceptible to VSV and may serve as sentinels for virus circulation.
An enzyme-linked immunosorbent assay for the detection of vesicular stomatitis virus antigen.

High percentages of positive samples were observed in CE In agreement with eqkina latter work, our data indicates that VSV is already circulating in these regions. Anais de microbiologia, v.
Vesicular stomatitis in Brazil I – Isolation and identification equiha the Alagoas strain. Journal of American Veterinary Medical Association, v. 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.
According to the ICTVthere are the least 20 additional serotypes to be characterizated. Journal of Medical Entomology, v.
The present study used 3, serum dstomatitis from horses of three Brazilian regions: Viral diseases to be differentiated from foot-and-mouth disease. Ecologic studies of vesicular stomatitis virus. Journal of Veterinary Diagnostic Information, v. Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: Caracterizacion antigenica e inmunogenica de varias cepas del sorotipo Indiana de estomatitis vesicular aisladas en Brasil.
Genetic and antigenic relationships of vesicular stomatitis viruses from South America. Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian States. 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.

Transmission and pathogenesis of vesicular stomatitis virus. The overall rate of seropositivity was Vesicular stomatitis virus VSV is a viral agent belonging to the order Mononegaviralesfamily Rhabdoviridaegenus Vesiculovirus.
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: Serogroup VSIV contains three subtypes: Outbreaks of vesicular stomatitis Alagoas virus in horses and cattle in northeastern Brazil. Moderate to high antibody prevalence in horses from NE states likely reflects the environmental conditions, estojatitis the climate, which favors the maintenance of large populations of insects especially mosquitoesprobable VSV vectors BENNETT et al.
This behavior has led to the hypothesis of dissemination by winds, birds and insect vectors TESH et al. Brazilian Journal of Veterinary Pathology, v. Unfortunately, we could not test the samples against VSV Cocal because we could not obtain a virus of this serotype.

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: Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al.
VSV naturally infects a variety of mammals including horses, cattle, swine, esromatitis mammals and equija. After complement inactivation, serum samples were diluted 1: OIE Terrestrial Manual1 may. In most cases, the disease is self-limiting and the clinical course lasts approximately two to three weeks REIS JR et al.
