Abstract

Genetic variability in Opisthorchis felineus from 6 Western Siberia rivers was studied using allozyme and multilocus DNA markers. Genetic subdivision of populations and the spatial genetic variability in O. felineus maritas were found to be the same when using two methods of analysis, but differed from these indices in metacercariae. Metacercariae from ide, dace and roach were not genetically different, indicating the absence of hostal subpopulations of the parasite. Low level of O. felineus genetic variability is not consistent with a pronounced population structure of intermediate hosts — Cyprinid fish.
