Prevalence of bovine campylobacteriosis in indigenous cattle of three states in Nigeria.

A survey of bovine campylobacteriosis in breeding bulls and cows was carried out in the states of Kaduna, Kano and Borno. Six hundred and eighty nine cattle composed of 585 and 104 breeding bulls and cows respectively were sampled. Campylobacter fetus subsp. venerealis was isolated from 12 bulls while Campylobacter fetus subsp. fetus was isolated from three of them. Campylobacter fetus subsp. fetus was isolated from four cows while Campylobacter fetus subsp. veneralis was isolated from one cow. The overall prevalence of campylobacteriosis in the three states was 2.9% (20/689). The result of the study identifies Campylobacter fetus subsp. venerealis as the agent of enzootic infertility in Nigeria and suggests that it may be a significant problem.
