ABSTRACT

To investigate the risk factors and bacterial infections associated with reproductive failure in dairy cows. Vaginal swabs and blood samples were collected from 408 cows in all farms visited in Khartoum North, Khartoum State, Sudan. The bacteria isolated from these vaginal swabs were 232(39.1%) Staphylococcus spp, 162(27.2%) Streptococcus spp, 150(25.2%) E. coli spp and 50 (8.5%) Pseudomonas spp. The prevalence rate of brucellosis was (16.2%). The number of bacteria isolated from cows with reproductive problem was higher than randomly sampled cows. Brucellosis seroprevalence was higher in problematic cows 43(20.8%) compared to randomly selected cows 23(11.4%) this difference was found to be significant with p< 0.05, and the relative risk of problematic cow to get brucellosis was twice the randomly selected cow. The antimicrobial sensitivity of the isolated Gram positive bacteria, was Vancomycine, Gentamycine and Amoxyclave are considered and that of Gram negative bacteria were Ciprofloxacine, Ampcilline, Gentamycine and Cotrimoxazole.
