Seroepidemiologic survey onWest Nile Virus, EquineInfectious Anemia Virus, Equine Arteritis Virus andInfluenza A Virus in the stables of Tehranand Alborzprovince

A seroepidemiological study to detect the presence of the antibodies against West Nile Virus(WNV), Influenza AVirus, Equine Infectious Anemia Virus (EIA) and Equine Arteritis Virus (EAV) was done in Tehran and Alborzprovince, Iran from April 2011 to July 2012. The objective of this study was to determine the serological statusof the most important viruses in horse. Serum samples were collected from stable horses throughout TehranandAlborzprovince. Out Of 126 samples, 3 (2.38%), 1 (0.79%), 37 (29.36%), 85(67.46%) were seropositive for WNV,EIA, EAV and Influenza A Virus, respectively. The results revealed that antibodies against WNV, EIA and EAVwere present in Tehran and Alborz province; meanwhile,previous exposure to WNV, EIA and EAV might nothave occurred in Iran due to low percentages ofWNV and EIA seropositive cases and medium percentage ofEAV seropositive results. Seropositivecases of WNV, EIA and EAV were as same as other reports. Since highpercentages of Influenza A seropositive results, the agent is likely circulating in Iran.
