A two-year-old male Japanese draft horse (known as a "Ban'ei horse") excreted eight cestodes. Based on their morphological features, they were identified as Anoplocephala perfoliata. The partial mitochondrial cytochrome c oxidase subunit 1 (COI) sequences of the worms were nearly identical to A. perfoliata isolated from horses in Europe. The results of phylogenetic analyses of COI revealed that our samples and the European isolates formed the same clade, which was separate from Chinese and Australian isolates. Ban'ei horses were developed by crossbreeding draft horses imported from European countries in the 1900s. Our results suggest that A. perfoliata was transported to Hokkaido with horses from Europe. To our knowledge, this is the first report of A. perfoliata infection in a Japanese draft horse.
一匹两岁的雄性日本挽马（称为“挽用马”）排出了八条绦虫。根据其形态特征，它们被鉴定为叶状裸头绦虫。这些蠕虫的线粒体细胞色素c氧化酶亚基1（COI）部分序列与从欧洲马匹中分离出的叶状裸头绦虫几乎相同。COI的系统发育分析结果表明，我们的样本和欧洲分离株形成了同一个分支，与中国和澳大利亚的分离株不同。挽用马是在20世纪通过将从欧洲国家进口的挽马进行杂交培育而成的。我们的结果表明，叶状裸头绦虫是随来自欧洲的马匹被运到北海道的。据我们所知，这是日本挽马感染叶状裸头绦虫的首次报告。
