Abstract: Chlamydophila abortus is one of the major causes of infectious abortion in pregnant sheep (Enzootic Abortion of Ewes) worldwide. Organisms shed through uterine discharges and placentas at lambing time are the main sources of environmental contamination, responsible for transmission to susceptible animals and possibly human. The disease is the most common infectious cause of lamb losses in several countries, resulting in major economic losses to agricultural industries. In the present study, sera from 145 ewes with history of abortion were analyzed for antibodies against C. abortus with a commercial ELISA kit (ELISAr, Institut Pourquier, France). According to the result, 13 ewes (13/145, 8.9%), were seropositive in ELISA test. There was not any correlation between infection and ages of seropositive ewes. In conclusion, enzootic abortion of ewes may be prevalent in Ahvaz and further attempts for definitive diagnosis by isolation of its etiologic agents are recommended.
