【 摘 要 】

Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran) by ELISA method. Blood samples were collected from 492 cattle in 41 farms. Antibodies to N. caninum were found in 63(12.80%) sera. A Significant difference was observed between seropositive cattle and dog presence in farm, dog contact with herd, abortion history and herd population. No significant differences were found between seropositive cattle and age as well as breed. This study is the first report of N. caninum infection in dairy cattle farms in Hamedan province. As per our knowledge, Neospora is an important factor in abortion of cattle in this region. Therefore, comprehensive studies for control strategies and improving management of dairy farms is necessary.
