We report one case of cystic echinococcosis (CE) in Japan in a native of Nepal. Ultrasonography and computed tomography scan of the liver revealed unique cystic lesions with or without daughter cysts of Echinococcus granulosus. Immunoblot analysis using crude antigens of E. multilocularis and cyst fluid of E. granulosus, without reference to these image analyses, strongly suggested this was a case of CE. We found protoscoleces in surgically removed hepatic lesions and analyzed the mitochondrial cytochrome c oxidase subunit I (COI) gene by the polymerase chain reaction. Based on the similarity in DNA sequences of the COI gene of this Echinococcus spp. with that of previously reported sheep-dog strain (GI), the parasite was considered to be the so-called common sheep strain of E. granulosus.
我们报告了日本1例尼泊尔籍囊性棘球蚴病（CE）病例。肝脏超声检查和计算机断层扫描显示有独特的囊性病变，伴有或不伴有细粒棘球绦虫的子囊。在未参考这些影像分析的情况下，使用多房棘球绦虫粗抗原和细粒棘球绦虫囊液进行免疫印迹分析，强烈提示这是1例CE病例。我们在手术切除的肝脏病变中发现了原头节，并通过聚合酶链反应分析了线粒体细胞色素c氧化酶亚基I（COI）基因。基于该棘球绦虫属COI基因的DNA序列与先前报道的羊-犬株（GI）的相似性，该寄生虫被认为是所谓的细粒棘球绦虫普通羊株。
