Theileria is a genus of parasites that belongs to the phylumApicomplexa, and is closely related to Plasmodium. Two Theileria species, T. annulata and T. parva, are important cattle parasites.[1]T. annulata causes tropical theileriosis and T. parva causes East Coast fever. Theileria species are transmitted by ticks.[2]
The genomes of T. orientalis Shintoku[3], Theileria equi WA,[4]Theileria annulata Ankara[5] and Theileria parva Muguga[6] have been sequenced and published.
Vaccines against Theileria are in development.[1][8] In May 2010, a vaccine that was reported to protect cattle against East Coast fever had been approved and registered by the governments of Kenya, Malawi, and Tanzania.[9]
