| Abstract: |
| Four species of Trichodina parasitizing the gills of cultured molluscs and fishes in China are described: Trichodina pectenis Stein, 1974 from the scallop Mizuhopecten yessoensis; Trichodina jadranica Raabe, 1958 from the fishes Mugil cephalus and Anguilla bicolor bicolor; Trichodina acuta Lom, 1961 and Trichodina rostrata Kulemina, 1968 from the fish Acrossocheilus fasciatus. The description of T. pectenis presented here first includes both live characters and morphometric data obtained from specimens impregnated using the wet silver nitrate and protargol methods. The other species were revealed by the dry silver nitrate method. Intensities of infestation and comparisons with related species and populations are provided for each of the four. |
| 中文摘要: |
| 车轮虫是一类主要寄生于贝类和鱼类体表的缘毛类纤毛虫原生动物。本文对分别寄生于海洋贝类－－虾夷扇贝Mizuhopecten yessoensis，半咸水鱼类－－鲻鱼Mugil cephalus和双色鳗鲡Anguilla bicolor bicolor，以及淡水鱼类－－光唇鱼Acrossocheilus fasciatus鳃表和体表的虾夷扇贝车轮虫Trichodina pectenis，亚卓车轮虫T.jadranica，急尖车轮虫T.acuta和喙状车轮虫T.rostrata，进行了详细的分类学研究。本文第一次报道了虾夷扇贝车轮虫的活体和蛋白银染色后特征，该虫体也是国内新记录种。其它三个车轮虫物种感染的鱼类，均属新纪录宿主。同时，也报道了这四种车轮虫对宿主的感染率和感染强度。 |
