    Trypanosoma brucei are extracellular protozoa transmitted to mammalian host by the tsetse fly. Analysis of genes affecting host's resistance to infection can reveal critical aspects of host-parasite interactions. T. b. brucei infects many animal species including livestock. Mouse strains differ greatly in susceptibility to T. b. brucei. However, genes controlling susceptibility to this parasite have not been mapped. We analyzed the genetic control of survival after T. b. brucei infection using CcS/Dem recombinant congenic strains, each of which contains a different random set of 12.5% genes of their donor parental strain STS/A on the BALB/c genetic background. The RC strain CcS-11 is even more susceptible to parasites than BALB/c or STS/A. In F2 hybrids between BALB/c and CcS-11 we detected and mapped four loci, Tbbr1-4 (Trypanosoma brucei brucei response 1–4), that control survival after T. b. brucei infection. Tbbr2 was precision mapped to a segment of 2.15Mb that contains 26 genes.
