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 Campylobacter fetus subsp. venerelias as the agent of enzootic infertility in smallholder herds and suggests that may be a significant problem.
