Ten lymphocyte antigens were defined in a flock of Scottish Blackface sheep known to be naturally exposed to infection with Ostertagia circumcincta. Population and family studies suggested that the 10 antigens were products of class I loci, Antigen G13br was in linkage disequilibrium with allele g2 at the DRB1 locus. The g2 allele has previously been associated with reduced faecal egg counts in a different crop of lambs from the same farm, In this study antigen G13br was also associated with a reduction in faecal egg counts. The results provide partial confirmation of the role of the major histocompatibility complex in resistance to natural, predominantly O. circumcincta infection.
