Description	Heterogeneities in immune responsiveness may affect key epidemiological parameters and the dynamics of pathogens. We analysed the influence of Major histocompatibility complex (Mhc) genes and epigamic traits on the response to phytohaemagglutinin in males from cyclic populations of the montane water vole (Arvicola scherman). We found a negative relationship between Mhc hetetozygosity and response to phytohaemagglutinin, mediated by a specific Mhc genotype (Arte-Dqa-05 homozygous genotype being a good’ Mhc variant in terms of immunogenetic quality). The development of the scent glands seems to be an honest signal for mate choice as it is negatively correlated with helminth load. The good gene’ hypothesis was not validated as Arte-Dqa-05 homozygous males did not exhibit larger glands. Besides, the negative relationship observed between the size of these glands and the response to phytohaemagglutinin, mainly for Mhc homozygotes, corroborates the immunocompetence handicap hypothesis.
