title: Prevalence of genital campylobacteriosis and trichomonosis in crossbred breeding bulls kept on zero-grazed smallholder dairy farms in the Tanga region of Tanzania.
abstract: A survey to demonstrate the presence or absence of genital campylobacteriosis and trichomonosis in cross-bred breeding bulls kept under smallholding dairy farms in the Tanga region of Tanzania was carried out during the period of January-June 1996. Sheath washings, swabs and preputial scrapings were collected from 58 randomly selected bulls. Campylobacter fetus subsp. venerealis was demonstrated in 3/58 (5.1%) and Tritrichomonas foetus in 0/58 (0%) of all bulls tested. Bull-level variables of level of taurine genes (62.5% taurine genes, F2; 75% taurine genes, F3) and age were not significantly associated with campylobacteriosis (P > 0.05). The result of the study identifies Campylobacterfetus subsp. venerelias as the agent of enzootic infertility in smallholder herds and suggests that may be a significant problem.
