Six dogs were found to be susceptible to experimental infections with a European isolate of Echinococcus multilocularis from southern Germany. Two cats were only poorly susceptible. Adult worms were not evenly distributed throughout the small intestine and the majority of parasites were found in the posterior region. The mode of attachment of E. multilocularis in the dog was similar to that for E. granulosus with the adult worm extending its rostellum deep within a crypt of Lieberkühn. In cats only few worms were found to have penetrated deeply between the villi. E. multilocularis was found to possess a modified group of rostellar tegumental cells, morphologically and functionally identical to those described in E. granulosus and previously referred to as the "rostellar gland". By studying development in vivo and in vitro, the time required for the production of shelled eggs was demonstrated to be only 28 days. Concurrent experimental infections in dogs with E. multilocularis and E. granulosus revealed that both species will develop together in the same host. Their development was not retarded in any way by the presence of the other and both species were able to coexist in the same area of the intestine.
六只狗被发现对来自德国南部的欧洲多房棘球绦虫分离株的实验性感染易感。两只猫仅有轻微易感性。成虫在小肠内分布不均，大部分寄生虫位于后部区域。多房棘球绦虫在狗体内的附着方式与细粒棘球绦虫相似，成虫将其顶突深入利伯kühn隐窝内。在猫体内，仅发现少数虫体深深穿透绒毛之间。多房棘球绦虫被发现具有一组经过修饰的顶突皮层细胞，在形态和功能上与细粒棘球绦虫中描述的细胞相同，此前被称为“顶突腺”。通过体内和体外发育研究，发现产生带壳卵所需的时间仅为28天。同时对狗进行多房棘球绦虫和细粒棘球绦虫的实验性感染表明，这两个物种可以在同一宿主体内共同发育。它们的发育不会因另一个物种的存在而受到任何阻碍，并且两个物种能够在肠道的同一区域共存。
