This paper undertakes an ex ante economic analysis of research on how resistance to trypanosomosis - a dominant livestock disease in Africa - can be maintained and enhanced while retaining and reinforcing characteristics of economic importance to farmers, and on how 'trypanotolerance' can be impa...

An ex ante economic and policy analysis of research on genetic resistance to livestock disease: Trypanosomiasis in Africa
Malaria and trypanosomiasis are vector-borne protozoal diseases which disproportionately affect the poor. Both give rise to immense human suffering; malaria exerts its effect directly on human health, while trypanosomiasis causes damage largely though its effect on the health and productivity of ...

Controlling malaria and African trypanosomiasis: The role of the mouse
Mice whose tumor necrosis factor alpha (TNF-) genes were disrupted developed higher levels of parasitemia than wild-type mice following infection with Trypanosoma congolense IL1180 or T. brucei brucei GUTat3.1, confirming the results of earlier studies. To determine whether TNF- directly affects ...

Tumor necrosis factor alpha (Tnf) plays a pleiotropic role in murine malaria. Some investigations have correlated Tnf with hypothermia, hyperlactatemia, hypoglycemia, and a suppression of the erythropoietic response, although others have not. In this study, we have evaluated parasitemia, survival...

Fine mapping of trypanosomiasis resistance QTLs in mice using advanced intercross lines
The heat shock protein (HSP) 70.1 gene lies on mouse chromosome 17 among the candidates for Tir1, the major quantitative trait locus associated with response to Trypanosoma congolense infection. To evaluate whether the HSP70.1 gene is involved in the response, we compared the susceptibility of HS...

Tumor necrosis factor-α (TNF-α) plays a role in the host’s defence against infections with African trypanosomes. It helps to control the blood stream form of the parasite and in Trypanosoma congolense infections, it also prolongs survival. The mechanisms by which this cytokine can influence paras...

Mapping of QTL influencing immunological responses to gastrointestinal nematode infection in mice. Abstract
Genome-wide quantitative trait locus (QTL) mapping was used to evaluate the genetic basis of resistance to Helgmosomides polygyrus in an F2 cross of SWR and CBA mouse strains that are resistant and susceptible, respectively, to infection. 25 significant QTL affecting at least one of the resistanc...
