Methods for determining the efficacy of animal health interventions involving vector-borne diseases when the intervention attempts to control the vector itself are described. There are a number of possibilities. For example, a before/after study can be undertaken when data collected following the...

Statistical issues in the design and analysis of animal health interventions for vector-borne disease
In this study, the efficacies of three trypanocidal drugs, diminazene aceturate, isometamidium chloride and homidium bromide, were evaluated in four representative areas of Cote d'Ivoire with different production systems, degree of integration of different trypanosomosis control approaches and de...

Trypanocidal drug resistance in West Africa
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...

Detecting resistance of trypanosomal infection to diminazene aceturate - a possible field test?
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...
