在四川省进行人类带绦虫病/囊虫病的常规流行病学调查时，从一名52岁藏族妇女身上发现一条膜壳绦虫成虫。基于核28 S核糖体DNA和线粒体细胞色素氧化酶亚基1序列的系统发育分析表明，该人分离物不同于引起人类膜壳绦虫病的常见寄生虫缩小膜壳绦虫和微小膜壳绦虫。遗憾的是，人类分离株的节片不适合进行形态学鉴定。然而，由此产生的后代发生证明了人类分离物是欧亚大陆姬鼠属的冬眠膜壳绦虫的姐妹种。目前的数据清楚地表明，引起人类感染的膜壳绦虫不仅限于H。diminutaandH.奶奶
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 cytochromecoxidase subunit 1 showed that the human isolate is distinct fromHymenolepis diminutaandHymenolepis 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 toHymenolepis hiberniafromApodemusmice in Eurasia. The present data clearly indicate that hymenolepidid tapeworms causing human infections are not restricted to onlyH. diminutaandH. nana.
