The susceptibility of G. longipennis, G. brevipalpis and G. morsitans centralis to various strains of Trypanosoma vivax, T. congolense and T. brucei brucei was investigated in the laboratory. Cattle and goats were infected with the trypanosomes and the tsetse fed from them during the first parasi...
