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...

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...

Trypanocidal drugs are the most widely applied method of trypanosomosis control in Africa and the only control method in Latin America and Asia . Treatment recommendations and strategies for chemotherapeutic control of trypanosomosis depends on information of trypanosomosis risk and the prevalenc...

Chemotherapy is the single most important strategy for the control of trypanosomosis in African livestock. Trypanocidal drug resistance is a growing problem across much of sub-Saharan Africa and increasingly recognised as a major threat to livestock production. It is therefore of pressing importa...

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 ...

The identification and tracking of sub-populations through time and space are critical to fully understanding the epidemiology of parasitic diseases. However, very little is known about the structure, distribution and dynamics of trypanosome populations in the field. Most laboratory studies that ...

The extent and significance of trypanocidal drug resistance was investigated in priority areas of three East and Southern African Countries under a project. The project was built on the results of two previous projects. Existing methods currently available for the demonstration of drug-resistance...

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...

Besides the in vitro test, two tests are very commonly used for the detection of trypanocidal drug resistance: the tests in mice and in ruminants. Since it has been shown that several parameters such as the number of trypanosomes inoculated and the time of treatment might influence the outcome of...
