Under most circumstances, certain breeds of domestic ruminants show a remarkable resistance to the effects of African trypanosomiasis: they can tolerate the presence of parasites while apparently controlling levels of parasitaemia and, crucially, not showing the the severe anaemia and production ...

A comparison of F2 and F6/7 inter-cross lines of mice, derived from CBA and SWR parental strains, has provided strong evidence for several previously undetected quantitative trait loci (QTL) for resistance to Heligmosomoides bakeri. Five QTL affecting average faecal egg counts and/or worm burdens...

Fine mapping of quantitative trait loci (QTL) associated with resistance to the gastrointestinal parasite Heligmosomoides polygyrus was achieved on F6/F7 offspring (1076 mice) from resistant (SWR) and susceptible (CBA) mouse strains by selective genotyping (top and bottom 20% selected on total wo...

Tsetse fly-transmitted trypanosomes (Trypanosoma spp.) cause 'sleeping sickness' in man and have a serious impact on livestock-based agriculture in large areas of Africa. Multigene control of variation in susceptibility to trypanosomiasis is known to occur in mice, where the C57BI/6 (B6) strain i...

African trypanosomes are protozoan parasites that cause “sleeping sickness” in humans and a similar disease in livestock. Trypanosomes also infect laboratory mice and three major quantitative trait loci (QTL) that regulate survival time after infection with T. congolense have been identified in t...


Goodhead, I.Archibald, A.L.Amwayi, P.Brass, A.Gibson, John P.Hall, N.Hughes, Monica A.Limo, M.K.H.Iraqi, F.A.Kemp, Stephen J.Noyes, H.A.[A comprehensive genetic analysis of candidate genes regulating response to Trypanosoma congolense infection in mice]A comprehensive genetic analysis of candidate genes regulating response to Trypanosoma congolense infection in mice

Some West African Bos taurus cattle breeds such as the N'Dama and a number of West African Shorthorns are resistant to tsetse fly-transmitted trypanosomosis. The trait is termed trypanotolerance, for which changes in packed red cell volume percent (PCV) and growth rate following infection are ge...
