报道从牙鲆 (Paralichthys olivaceus)体表溃烂组织分离的一种纤毛虫 ,通过活体观察、扫描电镜、蛋白银染色法、银浸法 ,对其形态学及纤毛图式做了研究。经鉴定 ,该纤毛虫为指状拟舟虫(Paralembus digitiformis Kahl,1933) ,隶属于寡膜纲、盾纤目、嗜污科、拟舟虫属。这是指状拟舟虫在牙鲆上兼性寄生的首次报道
A ciliophile isolated from the ulcerous tissue of Paralichthys olivaceus was reported. Its morphology and cilia pattern were studied by in vivo observation, scanning electron microscopy, silver staining and silver immersion. It has been identified that this ciliate is Paralembus digitiformis Kahl (1933), belonging to the order of the oligocapsid, sarcophagus, phytophagous, and canidon. This is the first report of a facultative parasitoid on the Japanese flounder
