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...

Knowledge, attitude and practices regarding the control of trypanosomosis in three countries in West Africa
We carried out a stratified, cluster-randomised, controlled trial in south Mali in 2004 to evaluate the impact of providing information on the diagnosis and treatment of bovine trypanosomosis by farmers. We recruited cattle farmers (444) in 46 villages and used stratified, restricted-randomisatio...

Training farmers in rational drug-use improves their management of cattle trypanosomosis: a cluster-randomised trial in south Mali
Trypanocidal treatments remain the most widespread method used for the control of African animal trypanosomosis (AAT). However increasing resistance affects the sustainability of this strategy. In general, resistance can be directly attributed to biological factors but it is recognized that insti...

This study assessed the degree of isometamidium resistance of trypanosomes infecting cattle in the upper Didessa valley of western Ethiopia. An initial prevalence study was conducted to identify sites with a high risk of trypanosmosis in cattle. The trypanosome prevalence varied widely, with t...

Cross sectional surveys (2002-2004) achieved in 89 villages, carried on 5474 cattle and 1908 tse tse flies (G. palpalis: 53%; G. tachinoides: 45% and G. morsitans: 2%) have been captured. Following these investigations, several suspected villages have been chosen for longitudinal surveys in order...

In a cross-sectional study carried out in June 1994, 486 cattle from 50 randomly selected dairy farms in the vicinity of Kampala, Uganda, were examined for trypanosome infections. The trypanosome prevalence (either positive with the haematocrit centrifugation technique [HCT] and/or the mini-anion...

Resistance to the drugs used to control African animal trypanosomosis is increasingly recognised as a constraint to livestock production in sub-Saharan Africa. The most commonly used tests for detection of trypanocidal drug resistance are tests using mice or ruminants, but these suffer from lack ...

Using a novel multilocus DNA marker analysis method, we studied the population genetic structure of Trypansoma brucei stocks and derived clones isolated from animal and rhodesiense sleeping sickness patients during a national sleeping sickness control program in Mukono district, Uganda. We then ...
