چکیده مقاله:

Seven hundred and sixty-eight blood samples of pregnant cattle from four Holstein dairy herds that are farmed in the vicinity of Tehran were usedto evaluate the seroprevalence of infection by enzymelinked immunosorbent assay (ELISA).Two hundred and ninety-eight of the768 blood samples (38.8%) were positive for this infection. The prevalence of infection in the herds varied from 18.7% to 65.1%. The abortion rate inseropositive and seronegative animals was 20.67% and 10.11%, respectively. Thus, the risk of abortion was approximately double the rate inseropositive cows (p<0.0005). There was a high correlation between the infection rate and the age in one herd. In other three herds, no significantcorrelation was found between infection rate and age. This is the first extended study with regards to the rate of infection in pregnant cattle in the vicinity ofTehran
