Abstract

Tritrichomonas augusta is a flagellated protozoan that parasitizes amphibians and reptiles. According to scanning electron microscopy (SEM), the cell shape of T. augusta varies from slender pyriform to ovoidal. Our data show the morphological features of the trophozoites: the emergence of the anterior flagella, the structure of the undulating membrane and the position and shape of the pelta, axostyle and posterior flagellum. In addition, herein we describe spherical forms which are probably pseudocysts. The description of the external structure of T. augusta, as demonstrated by SEM, contributes to the understanding of the biology of this parasite.

摘要

奥古斯塔三毛滴虫是一种寄生于两栖动物和爬行动物的鞭毛虫原生动物。根据扫描电子显微镜（SEM）观察，奥古斯塔三毛滴虫的细胞形态从细长梨形到卵形不等。我们的数据展示了滋养体的形态特征：前鞭毛的出现、波动膜的结构以及肋、轴柱和后鞭毛的位置和形状。此外，我们在此描述了可能为假包囊的球形形态。通过扫描电子显微镜所展示的奥古斯塔三毛滴虫外部结构的描述，有助于理解这种寄生虫的生物学特性。
