African animal trypanosomosis is an obstacle to the development of cattle rearing in teste fly-infested zones. However, not all cattle breeds have the same degree of susceptibility to the disease. Some West African breeds are even tolerant. Little use has yet been made of this diversity in breeding programmes, for want of data on its molecular and evolutionary origin. CIRAD, working with CIRDES, launched a wide-ranging study to analyse the response to infection of five West African breeds. Its conclusions have shown that shorthorn taurine breeds are remarkably tolerant of trypanosomosis.
