Description
Summary:This work presents the results of studying the molecular characteristics of parasitic tapeworms Echinococcus canadensis . The helminths were discovered during the autopsy of a wolf ( Canis lupus Linnaeus, 1758) killed by hunters in the Kirov oblast in 2021. A molecular phylogenetic study was performed by analyzing the sequence of a fragment of the first subunit of the mitochondrial cytochrome oxidase gene ( Cox I). It was found that the detected echinococci belong to the G10 genotype of E. canadensis , which is common in wolves in the northern territories of the Holarctic. We discovered four positions at which the substitutions characteristic only of this genotype are revealed. A substitution at one of the positions that is characteristic exclusively for the representatives of the G10 genotype found in Russia and Finland was also discovered.
