Taenia taeniaeformis were isolated from Norway rats captured at Sapporo (SRN isolate) and Kuala Lumpur, Malaysia (KRN) and from Bedford's gray red-backed voles at Toubetsu (TCR) and Abuta (ACR). SRN, KRN and TCR isolates showed similar degree of infectivity to various rodents in which cysticerci with hooks were obtained in laboratory rats, white tuberous lesions in mice and no cysts or lesions in Mongolian gerbils and voles. Contrary to this, inoculation with ACR isolate eggs resulted in strobilocerci formation in the liver of voles, but no cysts were observed in rats, mice or gerbils. This host specificity of ACR isolate to voles suggests that it might be a new species of Taenia.
从在札幌捕获的挪威大鼠（SRN分离株）、马来西亚吉隆坡的挪威大鼠（KRN）以及户别（TCR）和厚田（ACR）的贝氏棕背䶄中分离出了带状绦虫。SRN、KRN和TCR分离株对各种啮齿动物表现出相似程度的感染性，在实验室大鼠中获得了带钩囊尾蚴，在小鼠中出现白色结节性病变，而在蒙古沙鼠和䶄中未发现囊肿或病变。与此相反，用ACR分离株的虫卵接种导致䶄肝脏中形成链尾蚴，但在大鼠、小鼠或沙鼠中未观察到囊肿。ACR分离株对䶄的这种宿主特异性表明它可能是绦虫的一个新物种。
