最近在北海道发现了一只猫排泄多房棘球绦虫卵，这是日本首次观察到这种现象。这只猫是自由放养的，经常吃啮齿动物。粪便虫卵检查显示绦虫虫卵（EPG：440）和迭宫绦虫属。(EPG：>1000）。以大肠杆菌线粒体细胞色素c氧化酶亚基I基因的一部分为靶基因进行PCR。多房绦虫对3个单粒绦虫卵的DNA扩增均为阳性，其中1个扩增子经测序证实为E.多房的结果表明，E.分布于北海道的多房猫卵可经猫粪排泄，提示有必要进一步研究猫粪排泄的虫卵是否具有传染性，从而明确猫是否可作为日本人的传染源。
A cat excreting Echinococcus multilocularis eggs was recently identified in Hokkaido, representing the first such observation in Japan. The cat was raised free-range and frequently ate rodents. Fecal egg examination revealed eggs of taeniids (EPG: 440) and Spirometra spp. (EPG: >1000). PCR targeting part of the mitochondrial cytochrome c oxidase subunit I gene of E. multilocularis was positive with DNA from 3 single isolated taeniid eggs, and sequence analysis of one amplicon confirmed E. multilocularis. The results indicated that the eggs of E. multilocularis distributed in Hokkaido can be excreted in cat feces, and suggested the necessity of further studies to clarify whether the eggs excreted in cat feces are infective and thus whether cats can serve as infectious source to humans in Japan.
