摘要
通过活体显微观察及银染法对采自武汉东湖的4种固着缘毛类纤毛虫:粗茎睫纤虫Ophrydium crassicaule Penard,1922,念珠伪钟虫Pseudovorticella monilata(Tatem,1870)Foissner&Schiffmann,1974,垂盖虫Opercularia nutans(Ehrenberg,1831)Stein,1854和一个鞘居虫未定种Vaginicola sp.的活体、纤毛图式、银线系以及细胞核的形态学特征进行详细的描述,补充和完善了缘毛类纤毛虫的形态学资料,为纤毛虫分类和系统发育学的研究提供重要信息。此外,首次在伪钟虫中观察到有性生殖现象,为纤毛虫生殖进化的研究提供了基础资料。
Morphology of four sessile peritrichous ciliates from Donghu Lake, including Ophrydium crassicaulePenard, 1922, Pseudovorticella monilata （Tatem, 1870） Foissner ＆ Schiffmann, 1974, Opercularia nutants （Ehrenberg, 1831） Stein, 1854 and an unidentified species Vaginicola sp., were investigated through living observation, protargolstaining and silver impregnation. The detailed descriptions of living characters, infraciliature, silverline systems and dimorphic nuclei morphology were presented. These results reinforce the morphology data of peritrichous ciliates, andprovide important information to the taxonomy and phylogeny of ciliates. Furthermore, the first report of conjugationprocess of Pseudovorticella provided the basic knowledge for studying the sexual reproduction of ciliates.
