An average of 840 East African Zebu cattle from nine herds in the Ghibe Valley, southwest Ethiopia were monitored from 1986 to 1990. Each month blood samples were collected from analysis of packed red cell volume and detection of trypanosomes. Animals were found to be parasitaemic and with a PCV ...

Cattle from 50 farms in Mukono County, Uganda, were monitored for trypanosomes every second month over an 18-month period (1995–1996) by mini-anion exchange chromatography and haematocrit centrifugation techniques. Eighteen trypanosome isolates collected from cattle during this period were charac...

In 1986 a project was set up to determine the constraints to production of Zebu cattle under trypanosomiasis risk in the Ghibe valley. Approximately 1800 East African Zebu cattle (EAZC) were resident within the Ghibe valleey during the experimental period (1986 - 1992) and were maintained under t...

Sensitivity and specificity of the FAO/IAEA kits for diagnosis of bovine trypanosomosis were investigated using sera from experimental cattle infected by tsetse challenge with cloned populations of Trypanosoma congolense (three populations) or T. vivax (one population). The kits are based on mono...

The relationship between serum concentrations of the prophylactic trypanocidal drug isometamidium chloride and protection against tsetse challenge with two populations of Trypanosoma congolense was investigated in Boran (Bos indicus) cattle, using an isometamidium-ELISA. Isometamidium chloride (S...

Six Boran cattle were infected with the drug-resistant Trypanosoma congolense IL 3338. At the first peak of parasitemia different groups of 200 teneral Glossina morsitans centralis were fed once on each animal, just prior to treatment with diminazene aceturate at a dose of 3.5 mg kg-1 body weight...

Four Trypanosoma (T.) congolense reference clones with known isometamidium sensitivity and 16 T. congolense stocks from cattle in Kenedougou in south-western Burkina Faso, an area with known history of drug resistance, were characterised with the standard mouse test (SMT) and the drug incubatio...

Field studies were conducted to assess the occurrence of resistance to isometamidium chloride and diminazene aceturate in trypanosomes infecting cattle in Kenedougou Province of Burkina Faso. Forty-five of the 166 villages in Kenedougou were randomly sampled and visited to assess livestock numb...
