Abstract:
The invention relates to nucleic acid molecules which make it possible to detect those genes of the MHC involved in the phenomena of resistance or susceptibility to the development of virus-induced tumours. The primers developed from said molecules can be used in a method of genotyping farmed birds, and particularly chickens, characterised in that it comprises: amplification of a sample of nucleic acid originating from the animal to be studied using one or more pairs of primers capable of hybridising specifically with the nucleic acid of a polymorphic region of the Rfp-Y or B systems of the MHC of said birds, and detection of the PCR products obtained.
