Tritrichomonas mobilensis is an intestinal parasite of squirrel monkeys. There are few reports concerning the morphological aspects of this parasite. In addition, the taxonomic relationship between T. mobilensis and Tritrichomonas foetus, a serious pathogen that causes bovine and feline trichomonosis, has been questioned. For this reason, in the present study, we examined and compared both tritrichomonads with regard to their morphology, ultrastructure, endocytic activity and cytotoxicity when in the presence of host cells. Electron microscopy demonstrated consistent morphological differences between the hydrogenosomes of both parasites. Moreover, T. mobilensis and T. foetus had striking differences in their endocytic behavior. Thus, this work provides additional data that support the hypothesis that T. mobilensis is a distinct species from T. foetus.
纤毛滴虫 Mobilensis 是松鼠猴的肠道寄生虫。有关这种寄生虫形态方面的报道很少。此外，纤毛滴虫 Mobilensis 与 Tritrichomonas foetus 的分类关系一直存在争议，后者是一种严重的病原体，可引起牛和猫的滴虫病。出于这个原因，在本研究中，我们研究并比较了这两种纤毛虫的形态、超微结构、内吞活性和在存在宿主细胞时的细胞毒性。电子显微镜显示这两种寄生虫的氢化酶体之间存在一致的形态差异。此外，纤毛滴虫 Mobilensis 和 Tritrichomonas foetus 在其内化行为上存在显著差异。因此，这项工作提供了额外的数据，支持纤毛滴虫 Mobilensis 是与 Tritrichomonas foetus 不同的物种的假设。
