Tsetse control is often applied to an area which covers several herds. To carry out a trial using an uncontrolled area would be difficult because of the virtual impossibility of findings two areas identical in every respect. One solution (method 1) is to compare animal productivity before and aft...

Growth of exotic dairy calves in the tropics and subtropics has been investigated (Kabuga and Agyemang, 1984; Adeneye, 1985). Several non-genetic factors like season and year of birth, sex of calf, age and parity of dam, gestation length and management have been reported to influence preweaning p...

The significance of Glossina fusca group tsetse flies as vectors of cattle trypanosomiasis was examined using biconical traps to survey tsetse populations at one site in Gabon and two sites in Zaire. Mean trypanosome infection rates in G. tabaniformis Westwood over the study period ranged from 8....

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...

The response of peripheral blood mononuclear cells (PBMC) collected from cattle immunized with killed C. ruminantium to MAP1, MAP1-B, MAP2 and to a lysate of Cowdria was characterized in vitro. CD4+ T lymphocytes responded strongly to Cowdria lysates while B cells and gamma delta T cells prolifer...
