Molecular Characterization of Echinococcus canadensis (Cestoda, Taeniidae) in Wolf from the Kirov Region.

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 (CoxI). 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.

[The prevalence and prevention of alariosis].

High Alaria alata infestation rates were found in the animals of the Kirov Region. The functioning of alariosis foci is maintained by a wide range of primary and intermediate hosts. The purpose of this article was to evaluate the activity of disinfectants against A. alata trematode eggs and their effects on soil microbiocenoses.
