The overall rate of seropositivity was Blood-feeding behavior of vesicular stomatitis virus infected Culicoides sonorensis Diptera: Antibodies against vesicular stomatitis virus in horses from southern, midwestern and northeastern Brazilian States.

Vesicular stomatitis in Brazil I – Isolation and identification of the Alagoas strain. Financial impact of the outbreak of vesicular stomatitis on 16 beef ranches in Colorado.

Samples not presenting cpe were considered positive for VSV antibodies at the used dilution. Serogroup VSIV contains three subtypes: After complement inactivation, serum samples were diluted 1: Climatic and geographic influences on arboviral infections and vectors. Several samples from the Northeast and Midwest harbored high neutralizing titers, indicating a recent exposure to the virus.

Boletim del Centro Panamericano de Fiebre Aftosa, v. VSV naturally infects a variety of mammals including horses, cattle, swine, wild mammals and man. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. Brazilian Journal of Veterinary Pathology, v.

Moderate to high antibody prevalence in horses from NE states likely reflects the environmental conditions, especially vvesicular climate, which favors the maintenance of large populations of insects especially mosquitoes ewtomatitis, probable VSV vectors BENNETT et al.

The cultures were monitored for citopathic effect cpe for 72h. Animal gathering in fairs, races, artificial insemination centers and other events seem to facilitate virus spread among susceptible animals OKUDA et al. Because cattle is the most important host species for Estomatitls 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.

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. Ecologic studies of vesicular stomatitis virus.

American Journal of Epidemiology, v. Development and evaluation of an enzime-linked immunosorbent assay for the detection, typing and subtyping of vesicular stomatitis virus.

According to the ICTVthere are the least 20 additional serotypes to be characterizated.

Figure 1 presents the frequency and distribution of neutralizing titers by state. In most cases, the disease is self-limiting and the clinical course lasts approximately two to three weeks REIS JR et al. High percentages of positive samples were observed in CE Viral diseases to be differentiated from foot-and-mouth disease.

The present results validate this status because they indicated the circulation of VSV – likely serotype 3 – in horses from this region. Eduardo Furtado Flores, email: VSV infection is considered endemic in Brazilian northeastern States, where is probably under notified.

Estomatitis vesicular by Sharyn Monterrosa Barajas on Prezi

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, estomatotis study was designed to investigate circulation of VSV-3, through serology, in horses from three Estomafitis regions: This behavior has led to the hypothesis of dissemination by winds, birds and insect vectors TESH et al.

VS in clinically undistinguishable from foot-and-mouth disease FMDmaking critical its prompt differential diagnosis.

Residual antibodies were detected, probably reflecting remote past exposure to the virus in RS. Serological relationships between different strains of vesicular stomatis virus.

Caracterizacion antigenica e inmunogenica de varias cepas del sorotipo Indiana de estomatitis vesicular aisladas en Brasil. In this sense, the virus has been isolated from mosquitoes Phlebotomus and Aedesindicating their possible role in virus transmission HAYEK 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.

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: Epidemiologia de la stomatitis vesicular.

An enzyme-linked immunosorbent assay for the detection of vesicular stomatitis virus antigen. Our results reinforce the sanitary importance of this infection, contributing for its understanding, notification and control.

Vesicular stomatitis VS usually presents a seasonal pattern, whose incidence is usually higher in summer or in rainy seasons MASON et al.

Vesixular present study used 3, serum samples from horses of three Brazilian regions: OIE Terrestrial Manual1 may. Journal of General Virology, v.

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. Journal of Medical Entomology, v.

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. Genetic and antigenic relationships equija vesicular stomatitis viruses from South America. VSV isolates belong to two antigenically distinct serogroups:
