Parasites of Livestock

East Coast fever (ECF), which occurs in eastern, southern and central Africa, is an acute fatal disease of cattle caused by the tick-transmitted intracellular apicomplexan pathogen Theilera parva. Millions of cattle are at risk of ECF and approximately 1 million die each year. ECF alone is responsible for the death of half of all young calves in the region, and represents a major impediment to the development of the cattle industry, particularly among poor livestock owners. ECF-induced annual losses are estimated at more than US$300 million, a significant figure for resource-poor African agriculturalists. The African Cape buffalo (Syncerus caffer) is an asymptomatic wildlife carrier of T. parva in the region, and thought to be its primary host. Areas where buffalo and cattle co-graze are thought to facilitate transmission of the parasite between the two mammalian host by the tick vector.

The collaboration between IGS and ILRI focuses on the generation of genomic and transcriptomic data, and web-based resources for the study of T. parva. Other areas of collaboration include the application of reverse vaccinology approaches to the identification of novel antigens, and the use of in silico and laboratory experiments to better characterize the interactions between host and parasite.
