---

Theileria annulata (syn. Theileria dispar)

found in cattle and water buffalo, transmitted by Hyalomma spp. ticks and causes a clinical disease similar to east coast fever.

Theileria buffali

found in cattle and buffalo in Australia and transmitted by Haemaphysalis longicornis and H. bancrofti. Similar to T. mutans. Only sporadic cases of clinical disease and is seen mostly in splenectomized calves.

Theileria camalensis

found in camels, transmission thought to be by Hyalomma spp. ticks.

Theileria cervi

nonpathogenic, found in splenectomized deer.

Theileria dispar

see Theileria annulata (above).

Theileria hirci

found in sheep and goats. Transmitting vector uncertain but probably the tick Rhipicephalus bursa. Causes a disease similar to east coast fever in cattle.

Theileria lawrenci

found in cattle, buffalo and water buffalo. Transmitted by the tick Rhipicephalus appendiculatus; causes fatal corridor disease.

Theileria mutans

found in cattle, transmitted by ticks including Rhipicephalus and Haemaphysalis spp. and causes a benign bovine theileriasis.

Theileria orientalis

usually benign but can cause severe anemia in imported cattle.

Theileria ornithorhynci

found in platypus.

Theileria ovis

found in sheep and goats, transmitted by ticks of the genera Rhipicephalus, Dermacentor, Haemaphysalis and Ornithodoros spp. It causes a mild form of theileriasis.

Theileria parva

found in cattle, African buffalo and Indian water buffalo; transmitted by Rhipicephalus appendiculatus and possibly other ticks. It causes the widespread and serious disease east coast fever.

Theileria sergenti

doubtful identity; mostly benign in cattle.

Theileria tarandi

found in reindeer, transmitted by Ixodes persulcatus and causes an acute disease.

Theileria taurotragi

mildly pathogenic; found in cattle in Africa, Asia.

Theileria velifera

mildly pathogenic; found in cattle.
