Serological survey of Neospora caninum (Sarcocystidae) infection in beef cattle from Western Iran

The main purpose of this investigation was to evaluate the presence of Neospora caninum infection in beef cattle from Hamedan province, Western Iran. Blood samples were collected from 514 industrial beef cattle and tested using ELISA. IgG antibodies against N. caninum were found in 102 (19.8%) sera. Significant differences were observed between seropositive cattle and age group (p=0.022). No significant differences were found between seropositive cattle and breeding, dog presence in farm and dog contact with the herd (p>0.05). This study is the first report of N. caninum infection in beef cattle from western Iran. In conclusion, N. caninum was a considerable factor in beef cattle farms in Hamedan province. Therefore, further investigations in other hosts and designing control strategies for improving management in cattle farms is highly recommended.
