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...

Four Trypanosoma (T.) congolense reference clones with known isometamidium sensitivity and 16 T. congolense stocks from cattle in Kenedougou in south-western Burkina Faso, an area with known history of drug resistance, were characterised with the standard mouse test (SMT) and the drug incubatio...

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 ...

The aim of this study was to assess, whether polymerase chain reaction (PCR) allows sensitive screening of treatment failure suspicions in areas, where drug resistance against African animal trypanosomosis (AAT) appears to be a problem. PCR was used to detect trypanosome infections prior to, 14 ...

Drug resistant trypanosome infections in livestock have been Reported from 13 sub-Saharan countries so far, in eight of which multiple resistance occurs. Since new trypanocides are unlikely to appear on the market in the near future, information about the occurrence, extent and impact of drug res...

Trypanosomosis is an endemic disease in cattle in Mukono District in south eastern Uganda. A multi-disciplinary project was formulated in order to better understand the infection dynamics, and drug sensitivities, of the trypanosome parasites prevalent in Mukono, and also to assess the economic im...

The peri-urban dairy production systems in Uganda, located in the subhumid agro-ecological zone with medium rainfall have a high potential for livestock production (Walsche et al., 1991; Winrock, 1992), but medium tsetse challenge and the associated trypanosomiasis risk may adversely affect dairy...

To investigate the importance of trypanosomosis, resistance to trypanocidal drugs and the potential impact of integrated control measures on these factors, a 3-phase study was initiated. The first phase was a cross-sectional study in which tsetse apparent density, cattle trypanosome prevalence, t...

Animal African Trypanosomosis (AAT) and Human African Trypanosomosis (HAT), caused by a protozoa of the genus Trypanosoma (section Salivaria), are both diseases of significant importance to sub-Sahara Africa. Several species of Trypanosoma are found in Africa but only two subspecies of T. brucei,...
