Plasmodium-like round cells without sections of flagella, round flagellar cells with dividing nucleus and binuclear flagellate round forms were represented from the log-phase of Trichomonas vaginalis cultures. The fine-structural characteristics of the round cells support the opinion that the cells without flagella as well as the round multinuclear flagellate cells represent developmental stages preceding the appearance of mononuclear flagellate cells. In the round cells, amitotic division was observed instead of the well-known cryptopleuromitosis, without formation of metaphasic chromosomes and desmosomes. Our investigations onto the fine structure of the parasite support the assumption that the non-flagellate forms are viable cells of the parasite and point to still unknown phases of its biology.
在阴道毛滴虫培养物的对数期观察到类似疟原虫的无鞭毛节段的圆形细胞、有分裂细胞核的圆形鞭毛细胞和双核鞭毛圆形形态。圆形细胞的精细结构特征支持这样一种观点，即无鞭毛细胞以及圆形多核鞭毛细胞代表单核鞭毛细胞出现之前的发育阶段。在圆形细胞中，观察到的是无丝分裂，而不是众所周知的隐侧线有丝分裂，没有形成中期染色体和桥粒。我们对该寄生虫精细结构的研究支持了这样一种假设，即无鞭毛形式是该寄生虫的活细胞，并指出了其生物学中仍未知的阶段。
