Abstract
The molecular characteristics of parasitic tapeworms of the genus Echinococcus were studied. Helminths were discovered during the autopsy of a wolf ( Canis lupus Linnaeus, 1758), hunted in the Kirov region in October of 2021. Molecular phylogenetic study was performed by analyzing the sequence of a fragment of the mitochondrial cytochrome c oxidase subunit 1 (COI) gene. It was found that the obtained helminths belong to the G10 E. canadensis genotype, which is common in wolves in the northern territories of the Holarctic. Four positions were found for which substitutions characteristic only for this genotype are identified. A substitution was also found for one of the positions, which is characteristic only for representatives of the G10 genotype found in Russia and Finland.
