serological study of neospora caninum in pregnant dairy cattle in tehran, iran
Authors
abstract
seven hundred and sixty-eight blood samples of pregnant cattle from four holstein dairy herds that are farmed in the vicinity of tehran were used to evaluate the seroprevalence of neospora caninum infection by enzyme-linked immunosorbent assay (elisa). two hundred and ninety-eight of the 768 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 in seropositive and seronegative animals was 20.67% and 10.11%, respectively. thus, the risk of abortion was approximately double the rate in seropositive cows (p

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 si...
