IGLESIAS, G. M et al. Report of new alleles at BG loci in Camperos chickens. BAG, J. basic appl. genet. [online]. 2007, vol.18, n.1, pp.29-30. ISSN 1852-6233.

Camperos are meat-type chickens developed in Argentina that are under study for their response to disease. Nine new alleles were found in Campero chickens (from INTA EEA Pergamino) at the highly polymorphic BG loci within the Major Histocompatibility Complex (MHC), and were later reported to the GenBank (Accession numbers: DQ17443, DQ174444, DQ176443-DQ6449). All of them vary from previously reported BG alleles obtained from white Leghorn chickens and the Red Jungle Fowl from the Chicken Genome Project. Animals were selected from line-crossing among Plymouth Rock Red, Rhode Island Red and Cornish Red. Sequences reported add further evidence about the extreme diversity of these highly polymorphic, rapidly-evolving MHC genes.

Palabras clave : MHC; BG genes; Alleles; Camperos chickens.
