报道了一种新的寄主和地理位置记录。分别来自德克萨斯州和纽约的两种林蛙(Rana berlandieri和R.impiens)。在寄主的肝脏和肠系膜中发现了包膜的四甲状腺原虫。对这些甲状旁腺病毒的形态检查和对小鼠的实验接种表明，它们没有无性繁殖的能力。来自阿肯色州、得克萨斯州和纽约的无尾两栖动物的总体感染率较低，但感染强度普遍较高。此外，还对来自北美的青蛙和蟾蜍的寄主进行了综述。提出了一种新的解决方案。
A new host and geographic locality record is reported for tetrathyridia of Mesocestoides sp. in two species of ranid frogs (Rana berlandieri and R. pipiens) from Texas and New York, respectively. Tetrathyridia were found encapsulated in liver and mesenteries of the hosts. Morphological examination and experimental inoculation of these tetrathyridia into mice demonstrated the absence of capacity for asexual proliferation. Overall prevalence of infection was low in anurans from Arkansas, Texas and New York, but intensities can be generally high. In addition, a summary of frogs and toads from North America reported as hosts of tetrathyridia of Mesocestoides sp. is presented.
