Theileriosis is a general term used for infections in cattle with one or more of a number of Theileria species. Some of these may cause only mild or subclinical disease in cattle (so-called benign theileriosis), whilst others are extremely pathogenic, resulting in high mortality and severe economic losses. By far the most important and pathogenic Theileria species affecting cattle in Africa south of the Sahara is Theileria parva. Video link: Terminal stage of East Coast fever: severe dyspnoea and recumbency Distribution of the Theileria parasites in Africa Theileria parva infection is considered by many to be the most important tick-borne disease of cattle in eastern, central and southern Africa and is transmitted mainly by the brown ear ticks Rhipicephalus appendiculatus and Rhipicephalus zambeziensis. Infections typically cause an acute, often fatal disease of cattle, characterized by fever, enlargement of the lymph nodes and dyspnoea.
