Human chromosome (Chr) 18(HSA 18) contains approximately 85 million base pains of DNA. Thirty genes and pseudogenes have been mapped to HSA 18 by somatic cell genetics or in situ hybridization. Two bovine genes - Yamaguchi sacroma viral oncogene homology 1 (YESI) and desmocollin type 1 (DSC1) - h...

A preliminary search for QTLs in a cattle F2 resource populations segregating for trypanotolerance has revealed three large candidate chromosomal regions (Bta02, Bta05, Bta07). In order to narrow down the position of the trypanotolerant QTLs, we are building comparative chromosomal maps between c...

A small number of west African Bos taurus cattle breeds, including the N'Dama, constitute a valuable genetic resource by virtue of their ability to remain productive under trypanosomiasis challenge. However, introgression of Bos indicus genes into the trypanotolerant breeds, particularly by intro...

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...

Quantitative trait loci (QTL) associated with resistance to an intestinal worm in a well-defined murine model are described. These have been identified in an F(2) population derived from resistant (SWR) and susceptible (CBA) parental mouse strains infected with the gastro-intestinal nematode par...

DNA samples from 30 Friesian, 18 N'Dama, 30 Sahiwal and 18 Barotse (derived from Bos taurus and B. indicus) cattle were amplified by the polymerase chain reaction using previously described primer sequences for amplification of the Y chromosome locus INRA124. A polymorphism with 2 alleles was det...
