An adult hymenolepidid tapeworm was recovered from a 52-year-old Tibetan woman during a routine epidemiological survey for human taeniasis/cysticercosis in Sichuan, China. Phylogenetic analyses based on sequences of nuclear 28S ribosomal DNA and mitochondrial cytochrome c oxidase subunit 1 showed that the human isolate is distinct from Hymenolepis diminuta and Hymenolepis nana, the common parasites causing human hymenolepiasis. Proglottids of the human isolate were unfortunately unsuitable for morphological identification. However, the resultant phylogeny demonstrated the human isolate to be a sister species to Hymenolepis hibernia from Apodemus mice in Eurasia. The present data clearly indicate that hymenolepidid tapeworms causing human infections are not restricted to only H. diminuta and H. nana.
在中国四川进行的一次关于人体绦虫病/囊尾蚴病的常规流行病学调查中,从一名52岁藏族女性体内发现了一条成年膜壳绦虫。基于核糖体DNA 28S序列和线粒体细胞色素c氧化酶亚基1序列的系统发育分析表明,该人体分离株不同于引起人类膜壳绦虫病的常见寄生虫——微小膜壳绦虫和缩小膜壳绦虫。遗憾的是,该人体分离株的节片不适合进行形态学鉴定。然而,由此产生的系统发育结果表明,该人体分离株是欧亚大陆姬鼠体内的爱尔兰膜壳绦虫的姐妹种。目前的数据清楚地表明,引起人类感染的膜壳绦虫并不局限于微小膜壳绦虫和缩小膜壳绦虫。
