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 ...

Epidemiology of bovine trypanosomiasis in the Ghibe Valley, southwest Ethiopia. 2. Factors associated with variations in trypanosome prevalence, incidence of new infections and prevalence of recurrent infections
Approximately 390 East African Zebu calves from birth to 3 years of age and their dams were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cattle were individua...

It is useful to be able to estimate the incidence of new infections in cattle exposed to a high challenge of drug resistance trypanosomes; with this information the impact of an intervention that improves the control of trypanosomosis can be better understood. Approximately 750 Ethiopian Highland...

Bovine trypanosomiasis is prevalent in southwest Ethiopia infested with tsetse flies. Since 1986, East African Zebu cattle raised under trypanosomiasis risk in the Ghibe Valley of southwest Ethiopia have been studied to investigate the effects of trypanosmiasis on health and productivity.
