Control of tropical theileriosis (Theileria annulata infection) of cattle.
Tropical bovine theileriosis caused by Theileria annulata and transmitted by ticks of the genus Hyalomma may be controlled by one or more of the following methods: i) management, with particular emphasis on movement control; ii) vector control by application of acaricides, preventing transmission of disease; iii) treatment of clinical disease using specific chemotherapeutics; iv) immunization with live vaccines; and v) the use of cattle resistant to ticks or the disease. Of these the most important and effective control method is the use of a live cell culture vaccine attenuated by prolonged culture in vitro of mononuclear cells persistently infected with macroschizonts of T. annulata. This vaccine, used chiefly in susceptible taurine dairy cattle, can now be complemented by using novel chemotherapeutic naphthoquinones--parvaquone and buparvaquone--which are very effective in treatment of the clinical disease in these valuable cattle.
