ESTOMATITIS VESICULAR EQUINA PDF

Faukazahn American Journal of Epidemiology, v. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian States. In contrast, samples from RS had vessicular titers, possibly due to a past remote exposure.

Shagore Estomatitis vesicular equina pdf Development and evaluation of an enzime-linked immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus. Unfortunately, we could not test the samples against VSV Cocal because we could not obtain a virus of this serotype.

Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al. Climatic and geographic influences on arboviral infections and vectors. Outbreaks of vesicular stomatitis Alagoas virus in horses and cattle in northeastern Brazil. In contrast, samples from RS had low titers, possibly due to a past remote exposure.

Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus. Serological relationships between vesiclar strains of vesicular stomatis virus. The vesicularr study used 3, serum samples from horses of three Brazilian regions: Journal of Medical Entomology, v.

Journal of General Virology, v. OIE Terrestrial Manual1 may. In agreement with the latter work, our data indicates that VSV is already circulating vessicular these regions. Figure 1 presents the frequency and distribution of neutralizing titers by state. This is an open-access article distributed under the terms of the Creative Commons Attribution License.

After complement inactivation, serum samples were diluted 1: VSV infection is considered endemic in Brazilian northeastern States, where is probably under notified.

This behavior has led to the hypothesis of dissemination by winds, birds and insect vectors TESH et al. 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. Residual antibodies were detected, probably reflecting remote past exposure to the virus in RS.

High percentages of positive samples were observed in CE 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. The present results validate this status because they indicated the circulation of VSV — likely serotype 3 — in horses from this region.

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. Journal of American Veterinary Medical Association, v. The overall rate of seropositivity was Archives of Virology, v.

Vesicular stomatitis virus VSV is a viral equiina belonging to the order Mononegaviralesfamily Rhabdoviridaegenus Vesiculovirus. In this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK et al. Serogroup VSIV contains three subtypes: Eduardo Furtado Flores, email: Comparison of virus neutralisation and enzime-linked immunosorbent assay for the identification of antibodies against vesicular stomatitis Indiana 3 virus.

Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian States. Anais de microbiologia, v. 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.

The cultures were monitored for citopathic effect cpe for 72h. 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. According to the ICTVthere are the least 20 additional serotypes to be characterizated.

Because cattle is the most important host species for VSV infection — which it can be confounded estomaritis 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. 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. After complement inactivation, serum samples were diluted 1: Viral diseases to be differentiated from foot-and-mouth disease.
