Theileria orientalis occurs in Central Africa.

An outbreak of bovine theileriosis in Burundi was investigated and the occurrence of Theileria orientalis in Central Africa was confirmed for the first time. Its identity was established on morphological and serological grounds. The parasite was associated with clinical signs and further complicates the disease picture of bovine theileriosis in Africa. Amblyomma variegatum is suspected as being the local vector.
