Conference Paper 2000

Autor: Rowlands, G.J.

In this study, widespread resistance of T. congolense infections in East Highland Zebu cattle at Ghibe, southwest Ethiopia, to all available trypanocidal drugs has been demonstrated. Changes in incidence of T. congolense infections in cattle 36 months and more of age sampled between 1994 and 1997...

A tsetse control campaign using an insecticidal cypermethrin "pour-on" applied monthly to village Zebu cattle in Ghibe in southwest Ethiopia has been in operation for over six years. For four of these years farmers have paid a cost-recovery price for each animal given treatment. Relative densitie...

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...

Eleven groups of male cattle (39 on average per group) were monitored for presence of trypanosomes at 3-weekly intervals for periods of up to 27 weeks at a feedlot of Ferkessedougou, northern Cote d'Ivoire, in an area supposedly free of tsetse. All animals originated from or grazed during transhu...

Twelve traditional herds of cattle in the area of Boundiali, northern Cote d'Ivoire, were examined monthly from 1990 to 1992 for the presence of trypanosomes. The herds were randomised into 3 treatment groups, cattle in 4 herds received diminazene aceturate at 3.5 or 7 mg/kg body weight (b.w.) wh...

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...

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. Approxi...

Factors affecting the expression of trypanotolerance are discussed. Some of the factors which could influence the feeding preference of tsetse are physical - skin thickness, skin rippling; visual - coat colour, size; olfactory - breath, urine, skin secretions; behaviour - tail flicking, head swin...
