Abstract:
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.
摘要:
这项工作介绍了研究加拿大棘球蚴寄生虫的分子特征的结果。蠕虫是在狼的尸检中发现的(CanislupusLinnaeus,1758年),2021年在基洛夫州被猎人杀害。通过分析线粒体细胞色素氧化酶基因(CoxI)的第一个亚基的片段的序列进行了分子系统发育研究。发现检测到的棘球球菌属于加拿大大肠杆菌的G10基因型,这在北方领土的狼中很常见。我们发现了四个位置,在这些位置上揭示了仅该基因型的取代特征。还发现了在俄罗斯和芬兰发现的G10基因型代表特有的位置之一的替代。
