Blood samples were collected from parasitaemic cattle in the Ghibe Valley, Ethiopia, frozen in liquid nitrogen and transported to Nairobi, Kenya. Twelve of the stabilates were inoculated into individual Boran (Bos indicus) calves and characterised for their sensitivity, in turn, to diminazene ace...

Epidemiology of bovine trypanosomiasis in the Ghibe valley, southwest Ethiopia. 3. Occurrence of population of Trypanosoma congolense resistant to diminazene, isometamidium and homidium
Relationships were evaluated between trypanosome infection as measured by antigen detection enzyme immunoassays (antigen ELISA), anaemia as determined by average packed red cell volume (PCV), and animal performance as assessed by daily weight gain in 99 N'Dama cattle in Gabon exposed to natural t...

Evaluates possible contributions of the antigen-detection enzyme immunoassays (ELISA) for the diagnosis of Trypanosoma vivase, T.congolense, and T.Bucei infections in N'Dama cattle in Gabon, Central Africa. The assays are based on monoclonal antibodies which recoginse trypanosome antigens specifi...

Use of antigen-detection immunoassays in assessment of trypanotolerance in N'Dama cattle
Discusses trypanotolerance in cattle and prospects for the control of trypanosomiasis by selective breeding in Africa. Looks into methods available for control including tsetse control, drugs & vaccination and discusses constraints that limit the control. Also discusses prospects for future contr...

A method is described for calculating new infection incidence from monthly field data collected between April 1994 and February 1998 from an average of 770 Ethiopian Highland Zebu cattle maintained under traditional management in the Ghibe valley, southwest Ethiopia and exposed to a high challeng...

Trypanosome infection was detected by the dark ground/phase contrast buffy coat microscopic technique in N'Dama cattle in a high natural tsetse challenge situation in Zaire. The data were used to compare the pattern of infection in very young animals and in their dams, and to evaluate how the pat...
