Plain-English summary
This study reports the first discovery of equine arteritis virus (EAV), which can affect horses, in Argentina. The virus was found in the semen of a stallion that had been imported and was kept in isolation at a breeding farm in Tandil, Buenos Aires Province. Researchers confirmed the presence of the virus using specialized tests on the semen. This is significant because it marks the first time EAV has been identified in South America, which could impact the horse industry and the trade of horses and their semen in and out of Argentina.
Abstract
This paper describes the first isolation of equine arteritis virus (EAV) in Argentina. The virus was isolated from the semen of an imported seropositive stallion held in isolation at a breeding farm in Tandil in the Buenos Aires Province. In addition, viral nucleic acid was detected in seminal plasma using the reverse-transcription polymerase chain reaction. The isolated virus was propagated in cell cultures and confirmed as EAV by indirect immunofluorescence and virus neutralisation, using a serum specific for the reference Bucyrus strain of EAV. As far as the authors are aware, this is the first time that EAV has been isolated in South America. The equine industry is very important for Argentina and international movement of horses is very intensive. This finding may have effects on the international trade of horses and semen from Argentina.
