To determine the duration after treatment of cattle with diminazene aceturate that the drug influences the tsetse infectivity and transmissibility of a drug-resistant Trypanosoma congolense, six Boran cattle were infected with T. congolense IL 3338 via the bites of Glossina morsitans centralis. At the first peak of parasitaemia, different groups of 120(More)
