Taenia tapeworms of Finnish and Swedish wolves (Canis lupus) and Finnish brown bears (Ursus arctos), and muscle cysticerci of Svalbard reindeer (Rangifer tarandus platyrhynchus), Alaskan Grant's caribou (Rangifer tarandus granti) and Alaskan moose (Alces americanus) were identified on the basis of the nucleotide sequence of a 396 bp region of the mitochondrial cytochrome c oxidase subunit 1 gene. Two species were found from wolves: Taenia hydatigena and Taenia krabbei. The cysticerci of reindeer, caribou and one moose also represented T. krabbei. Most of the cysticercal specimens from Alaskan moose, however, belonged to an unknown T. krabbei-like species, which had been reported previously from Eurasian elks (Alces alces) from Finland. Strobilate stages from two bears belonged to this species as well. The present results suggest that this novel Taenia sp. has a Holarctic distribution and uses Alces spp. as intermediate and ursids as final hosts.
根据线粒体细胞色素c氧化酶亚基1基因396bp区域的核苷酸序列，鉴定了芬兰和瑞典狼（Canis lupus）、芬兰棕熊（Ursus arctos）体内的带绦虫，以及斯瓦尔巴德驯鹿（Rangifer tarandus platyrhynchus）、阿拉斯加格兰特驯鹿（Rangifer tarandus granti）和阿拉斯加驼鹿（Alces americanus）肌肉中的囊尾蚴。在狼体内发现了两种带绦虫：泡状带绦虫和克氏带绦虫。驯鹿、驯鹿和一头驼鹿的囊尾蚴也为克氏带绦虫。然而，阿拉斯加驼鹿的大多数囊尾蚴标本属于一种未知的类似克氏带绦虫的物种，该物种先前已在芬兰的欧亚驼鹿（Alces alces）中报道过。两只熊的成虫阶段也属于该物种。目前的结果表明，这种新的带绦虫物种具有全北区分布，以驼鹿属动物为中间宿主，以熊科动物为终末宿主。
