| Description | Gibel carp (Carassius gibelio) is an invasive species widely distrib¬uted in Europe. The populations of gibel carp are often composed of asexual and sexual specimens. Asexual females reproduced by gynogenesis when the eggs are activated by the sperm of conspe-cific or phylogenetically related males. In the line with the Red Queen hypothesis, the asexual form or the most common genetic clone of asexuals is the target of parasite adaptation, whilst sexual form may escape from parasites. The genes of major histocom¬patibility complex (MHC) genes play the key role in vertebrate adaptive immunity and resistance to parasites. We investigated the variability of major histocompatibility (MHC) genes of the class IIB and the associations between MHC genes and parasitism in the selected population of gibel carp during three consecutive years. We showed the temporal differences in parasite load as well as in MHC allelic profile of sexual and asexual forms, and revealed several associations between parasite species and MHC alleles. |
