[High serological prevalence of bovine anaplasmosis in North-Cameroon].

Between 1989 and 1994, cases of acute bovine anaplasmosis were rarely diagnosed in Northern Cameroon. However, the Becton-Dickinson anaplasmosis card test revealed high prevalence rates, especially in the North and Far North provinces. Bovine anaplasmosis might be clinically important in areas where the proportion of non-immune cattle is higher.
