This book provides an up-to-date account of what is known about the tick-borne protozoan parasite Theileria parva. Disease caused by T. parva in cattle, particularly East Coast Fever, is one of the most important constraints to improving livestock productivity in eastern and southern Africa. Despite extensive research efforts, control and prevention of the disease is extremely challenging and, by placing a substantial economic burden on resource-poor livestock owners, it is a key factor in perpetuating poverty in rural communities. Beginning with a brief history, the book provides: - An account of the biology and distribution of the parasite, its tick vector and the nature of the disease, including immunity and genetic resistance. - A review of measures used for its control or prevention. - Important ancillary information which is not readily accessible in the scientific literature. - A concluding discussion of recommended research priorities for the future. The book brings together current knowledge about the parasite into a single volume for the first time in decades and forms a valuable resource for all researchers of human and animal protozoal diseases. It will also be of major interest to animal health workers, livestock farmers, government policy makers, scientific advisors and donor organizations.
