title: Three new MHC haplotypes in broiler breeder chickens.
abstract: Six distinct serotypes of the chicken B blood group system (which encodes the major histocompatibility complex) were identified in a commercial broiler breeder line (Line C). The B serotypes were compared by B-G restriction fragment length polymorphism (RFLP) analysis, allele-specific PCR typing test for B-LBII family genes and nucleotide sequence analysis of expressed B-F and B-LBII family genes. The results indicated the existence of seven distinct B haplotypes. Nucleotide sequence analysis demonstrated that three of the Line C haplotypes encode new B-F and B-LB alleles.
