The majority of trypanosomiasis cases occur in areas where the tsetse fly is found as this is the vector for all Trypanosoma spp. that affect cattle. T. vivax causes peracute disease, pyrexia and rapid death. T. brucei brucei causes an acute disease which, if untreated, will result in death. T. congolense causes a more chronic disease with anaemia and weight loss. Diagnosis is confirmed by thick and thin blood smears stained with Giemsa. Treatment is with diminazene aceturate, homidium bromide and chloride, and isometamidium chloride. The latter also has some prophylactic value but does not treat T. b. brucei.
