Tropical theileriosis or Mediterranean theileriosis is a theileriosis of cattle from the Mediterranean and Middle East area, from Morocco to Western parts of India and China. It is a tick-borne disease, caused by Theileria annulata. The vectors are ticks of the genera Hyalomma and Rhipicephalus.
The most prominent symptoms are fever and lymph node enlargement. But there is a wide range of clinical manifestations, especially in enzootic areas. Among them, the Doukkala area of Morocco, where the epidemiology and symptomatology of the disease were minutely studied.[1]
The disease was once considered as "benign" in the literature, in comparison to East Coast fever. With the introduction of European breeds into the region, however, it could become of major economic incidence.[2] An efficient treatment with parvaquone, then buparvaquone became available in many countries from the mid-1990s. Animals native to endemic areas appear more tolerant to the disease, buffalos especially, appear less susceptible.[3]
