Theileria mutans infection in Nigerian cattle

In a 12 year survey in the former Northern Provinces of Nigeria antibodies to Theileria mutans were found to have a prevalence rate of 32.6 to 85%. The indirect fluorescent antibody test was found to be more efficient than thin blood smear examination in detecting cattle exposed to T. mutans. The high prevalence of T. mutans infection was attributed to the high prevalence of Amblyomma species in the area under study.
