BACKGROUND: Equine arteritis virus (EAV) causes respiratory disease, abortion and sometimes, neurological signs. Stallions which are permanently infected with the virus, are the constant carriers of the virus in their semen and transmit the virus to other horses through sexual contact. OBJECTIVES: The aim of this study was to evaluate EAV infection in horses in four provinces of Iran and its relationship with age, sex, and race. METHODS: Blood samples were taken from 149 horses with different sex, age and race with history or clinical signs associated with equine viral arteritis, including the manifestation of respiratory disease (fever, nasal secretion, coughing), nervous signs (ataxia, dysmetria, recumbency) and abortion. The commercial ELISA kit was used for viral antibody detection. RESULTS: From 149 sampled horses, 11 cases (7.4%) were found to be positive for EAV. Seropositive cases were recorded in Tehran (2.7%), Golestan (4.3%), Khuzestan (6.7%) and West Azerbaijan (23.8%) provinces. CONCLUSIONS: This survey confirmed the presence of EVAV in horses from four provinces of Iran with the sensitive (98.3%) and special (98.9%) test. Therefore, consideration should be given to the control and prevention programs for the spread of this virus.
