Genotypic diversity of snails Succinea putris L. (Linnaeus, 1758) collected in the north-west of Russia and in the Republic of Belarus was analysed. Homology between the nucleotide sequences of snails from different population made up 100% by the nucleotide sequence of ITS1-5.8S-ITS2 region of rDNA. Genetic variability based on mitochondrial markers was insignificant. Average genetic distances between samples made up 0,009 for СOI gene loci and 0.008 for CytB gene loci. Was found ten haplotypes of the mitochondrial gene CytB and nine haplotypes of the mitochondrial gene СOI. Perhaps the genetic homogeneity of snails S. putris found in the study explains a low variability of their parasites, trematodes from the genus Leucochloridium.
