Host ability to control the Development of trypanosomes is a major component of trypanotolerance. However, practical indicators of the parasite control capability have still to be identified as they rely on the availability of more precise diagnostic techniques that could be carried out at the fa...

Reports the feeding preferences of Glossina species at sites of the African Trypanotolerant Livestock Network. Estimates tsetse challenge and relates the results with trypanosome prevalence in cattle. Examines the relationship between tsetse challenge using linear regression analysis. Also examin...

Autor: Trail, J.C.M.

Discusses ILCA's contribution towards the conservation of animal genetic resources, particularly studies on trypanotolerant livestock in West & Central Africa and evaluation of the potential of the Sahiwal breed to contribute to milk & beef production programs in Africa.


Trail, J.C.M.[Work on conservation of animal genetic resources by the International Livestock Centre for Africa (ILCA)]Work on conservation of animal genetic resources by the International Livestock Centre for Africa (ILCA)

Earlier research had provided clear indications of an ability of N'Dama cattle to acquire, over time, some control of the Development of parasitaemia following a T. vivax infection but not apparently, following a T. congolense infection. The objective of this study is to further assess the import...
