Introgression of trypanotolerance genes
Trypanosomosis is the most widespread parasitic disease of great importance in Africa affecting human and animals. There are breeds of cattle that are trypanotolerant. Trypanotolerance is an ability of these breeds to withstand the effects of trypanosome infections. The disease impedes production in Sub-Saharan Africa. In this thesis, the main focus is

Integrated control of vector-borne diseases of livestock--pyrethroids: panacea or poison?
, 2003 Tick- and tsetse-borne diseases cost Africa approximately US$4-5 billion per year in livestock production-associated losses. The use of pyrethroid-treated cattle to control ticks and tsetse promises to be an increasingly important tool to counter this ...

Genetic aspects of control of anaemia development in trypanotolerant N'Dama cattle
Acta Tropica, 1991 148 one-year-old N'Dama cattle, progeny of 29 sires, were exposed for 92 days to a medium natural tsetse-trypanosome challenge in Gabon, Central Africa. Matching health and performance data were recorded on 11 occasions. Average packed red cell volume percent (PCV) and lowest PCV reached during the period were evaluated as measures of ability to ...

Both Type-I and Type-II Responses Contribute to Murine Trypanotolerance
Journal of Veterinary Medical Science, 2009 The host immune system has been documented to influence the course and outcome of infection with the phospholipase-C-deficient (PLC(-/-)) Trypanosoma brucei brucei. We addressed the resistant mechanisms during trypanosomosis by comparing the immune response to variant-specific surface glycoprotein (VSG) in relatively susceptible C3H mice and ...
