由于几个分类学问题的积累，蛭形纤毛虫的分类是困难的。本研究从中国两种淡水/海洋藻类的表面分离到了三种尚未被详细描述的阴道菌，分别是阴道菌（Pyxicola pusilla,Cothurnia ceramicolaandVaginicola tincta）。本研究首次发现了pyxicolais和vaginicolais的纤毛，证明了多动性的分类价值。首次对上述物种的小亚基rDNA、ITS1-5.8S rDNA- its2区和大亚基rna进行了测序。系统发育分析表明，pyxicolae与cothurniae亲缘关系较近。本研究表明，在富营养化进化过程中，该物种可能代表了一个独特的谱系，并且thurniae属和thuricolae属都是单系的。脓疱疮、阴道癣、阴道癣均属禁忌。
The classification of loricate peritrich ciliates is difficult because of an accumulation of several taxonomic problems. In the present work, three poorly described vaginicolids,Pyxicola pusilla,Cothurnia ceramicolaandVaginicola tincta, were isolated from the surface of two freshwater/marine algae in China. In our study, the ciliature ofPyxicolaandVaginicolais revealed for the first time, demonstrating the taxonomic value of infundibular polykineties. Thesmall subunit rDNA, ITS1-5.8S rDNA-ITS2 region andlarge subunit rDNAof the above species were sequenced for the first time. Phylogenetic analyses based on these genes indicated thatPyxicolaandCothurniaare closely related. The present study suggested that the loricate species probably represent a distinct lineage in peritrich evolution and both generaCothurniaandThuricolaare monophyletic.Pyxicola pusilla,Cothurnia ceramicolaandVaginicola tinctaare recircumscribed.
