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...

Drug sensitivity of trypanosome populations from cattle in a peri-urban dairy production system in Uganda
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...

Testing of trypanocidal drug sensitivity in stabilates of pathogenic trypanosomes derived from cattle continues to be problematic, in spite of Development of in vitro techniques, since these are generally complicated and costly for the resources available in developing country laboratories. Furth...

A simplified cost-effective method for area-wide testing of trypanocidal drug sensitivity of T. congolense in mice
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 ...

Tsetse-transmitted trypanosomosis affects cattle production over approximately 10 million km2 of Africa. In these areas, trypanocidal drugs, both prophylactic and curative, are the most widely used methods of trypanosomosis control. However, resistance of trypanosomes to the 3 trypanocidal drugs ...
