SUMMARY
Equine viral arteritis virus (EAV) is a respiratory, viral, contagious disease of
equines and the caused by a virus of the genus Arterivirus (EVA). The disease is
characterized by lesions in small vessels, especially arterioles. The disease usually
runs as subclinical or acute. EAV infection can cause flu-like symptoms or respiratory
symptoms in adult horses, abortion in pregnant mares, interstitial pneumonia in young
foals, and persistent infection in stallions. Infection is possible only in equines and it is
transmitted horizontally, either by aerosol or respiratory infection of susceptible
horses or in natural or artificial insemination of mares with persistently infected
stallions. Since serological tests have been developed serum neutralization test (SN),
indirect immunofluorescence, agar gel immunodiffusion and ELISA test, and is
currently the most commonly used are ELISA and SN test (Timoney, 2008; OIE 2008).
In this study blood samples were collected from seven mares, which are used
for mating. Serum neutralization test showed that there are 5 animals with a positive
finding which is 71.43% of positive animals in the herd. Animals that have a positive
antibody titers were repeatedly thought alike, all animals had reproductive problems
but only one head came to abortion. Animals that have negative findings were first
thought alike. For them, even though they stick together with other throats, there was
no horizontal transmission of the virus. Positive animals exhibit some reproductive
problems that can, but not exclusively, be attributed to this virus.
