Transmission and pathogenesis of vesicular stomatitis virus. Comparison of virus neutralisation and enzime-linked immunosorbent assay for the identification of antibodies against vesicular stomatitis Indiana 3 virus.
Epidemiologia de la stomatitis vesicular. An enzyme-linked immunosorbent assay for the detection of vesicular stomatitis virus antigen.
In this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al. According to the ICTVthere are 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.
VSV infection is considered endemic in Brazilian northeastern States, where is probably under notified. Anais de microbiologia, v. Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: 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 cultures were monitored for citopathic effect cpe for 72h.
Southern, Midwestern and Northeast. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation.

Samples not presenting cpe were considered positive for VSV antibodies at the used dilution. Several samples from the Equnia and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus. Outbreaks of vesicular stomatitis Alagoas virus in horses and cattle in northeastern Brazil.
Eduardo Furtado Flores, email: Ecologic studies of vesicular stomatitis virus. Journal of Veterinary Diagnostic Information, v. 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.
The present study used 3, serum samples from horses of three Brazilian regions: Financial impact of the outbreak of vesicular stomatitis on 16 beef ranches in Colorado. Development and evaluation of an enzime-linked immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus.
In contrast, samples from RS had low titers, possibly due to a past remote exposure. Vesicular stomatitis VS usually presents a seasonal pattern, whose incidence is usually higher in summer or in rainy seasons MASON 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.
Vesicular stomatitis virus VSV is a viral agent belonging to the order Mononegaviralesfamily Rhabdoviridaegenus Vesiculovirus.
The overall rate of seropositivity was Caracterizacion antigenica e inmunogenica de varias cepas del sorotipo Indiana de estomatitis vesicular aisladas en Brasil. American Journal of Epidemiology, v. Climatic and geographic influences on arboviral infections and vectors.
After complement vesiculxr, serum samples were diluted 1: Equiha results reinforce the sanitary importance of this infection, contributing for its understanding, notification and control. In Brazil, positive serology to VSV has been detected in several states and different animal species.

VS in clinically undistinguishable from foot-and-mouth disease FMDmaking critical its prompt differential diagnosis. Journal of Medical Entomology, v. Journal of American Veterinary Medical Association, v. This is an open-access article distributed under the terms of the Creative Commons Attribution License. In most cases, the disease is self-limiting and the clinical course lasts approximately two to three weeks REIS JR et al.
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. Moderate to high antibody prevalence in horses from NE states likely equuina the environmental conditions, especially the climate, which favors the maintenance of large populations of insects especially mosquitoesprobable VSV vectors BENNETT et al.
Figure 1 presents the frequency and distribution of neutralizing titers by state. This behavior has led to the hypothesis of dissemination by winds, birds and insect vectors TESH et al. 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:
