Studies related to internal parasitic infestations and their association with genetic diversity in MHC region has suggested that some alleles of MHC DRB gene might augment the immune response against parasitic antigens and also may hamper parasitic fecundity inside the host. | Nội dung Text Sequence characterization of Ovine MHC Class II DRB I Gene in Indian sheep breeds
