We report here metacestode from the lung lobe of a semi-domesticated reindeer (). The specimen was detected within a development project concerning remote post mortem inspection at a reindeer abattoir in Sweden. Post mortem inspection was performed according to a routine on-site official meat inspection protocol. The species identification to was confirmed based on the DNA extracted from the metacestode, which was analysed by sequencing of the cytochrome c oxidase subunit 1. Firstly, our finding shows that semi-domesticated reindeer in addition to several other cervids can act as an additional intermediate host for . Secondly, it further confirms that this parasite is more widely distributed on the Scandinavian peninsula than what has previously been shown. This is in line with a previous molecular finding of adult from the Eurasian lynx () in Sweden and demonstrates that new intermediate host can be detected. Whether the present finding can be regarded as accidental or have created opportunities for an expansion throughout the northernmost Scandinavian Peninsula remains to be seen.
我们在此报告从一头半驯化驯鹿的肺叶中发现的多头蚴（ ）。该标本是在瑞典一个驯鹿屠宰场关于远程尸检的开发项目中检测到的。尸检按照常规的现场官方肉类检查规程进行。基于从多头蚴中提取的DNA，通过细胞色素c氧化酶亚基1测序分析，确认了该物种为 。首先，我们的发现表明，除了其他几种鹿科动物外，半驯化驯鹿可作为 的额外中间宿主。其次，这进一步证实该寄生虫在斯堪的纳维亚半岛的分布比之前所显示的更为广泛。这与之前在瑞典从欧亚猞猁（ ）体内发现 的分子研究结果一致，表明可能会检测到新的中间宿主。目前这一发现是偶然现象还是为其在斯堪的纳维亚半岛最北部的传播创造了机会，仍有待观察。
