Serological survey for equine viral arteritis in several municipalities in the Orinoquia region of Colombia

Objective. The goal of this study was to determine the current status of the Equine Arteritis virus (EAV) in horse populations in the Orinoquia region of Colombia. Materials and methods. A transversal study was conducted by serological survey of equine (n=100) from 11 municipalities of the Colombian Orinoquia region. Serum samples were tested by virus seroneutralization assay according to the guidelines provided by the World Organization for Animal Health. Results. After testing was carried out no positives samples to EAV were found in the population analyzed. Conclusions. Although the sample size of the population screened in this study does not represent the total equine population size for the region or the country, data obtained has shown the absence of EAV infection in these animals. However, a wider study area including other regions of the country, with a feasible statistical design, would determine if this infection continues to be an exotic disease for Colombia.
