六鞭毛科 (Hexamitidae)属动鞭纲 (Zoomastigophorea)、双体目 (Diplomonadida)。自Moore首次报道寄生于鱼类的六鞭毛虫始 ,到目前为止 ,已报道寄生于鱼类的六鞭毛虫 ,共计 30余种 ,分别隶属于六鞭毛虫属 (Hexamita)和旋核鞭毛虫属 (Spironucleus)。作者发现五新种 ,它们是寄生于细鳞斜颌鲴 (XenocyprismicrolepisBleeker)的关桥六鞭毛虫 (Hexamitaguanqiaoensissp .nov.)、寄生于黄尾鲴 (XenocyprisdividiBleeker)的梁子湖六鞭毛虫 (Hexamitaliangzihuensissp .nov.)和微小旋核鞭毛虫 (Spironucleusminutussp .nov .)、寄生于银鲴 (XenocyprisargenteaG櫣ｎｔｈｅｒ)的多形六鞭毛虫 (Hexamitavarformissp .nov .)和粒状旋核鞭毛虫 (Spironucleusgranularissp .nov.)。采用蛋白银染色方法 ,对寄生于鱼类的六鞭毛虫进行了研究。
Hexamitidae is a member of the family Zoomastigophorea and Diplomonadida. Since the first report of Moore on six flagellates parasitized in fish, up to now, six species of hexapod parasites in fish have been reported, accounting for more than 30 species, belonging to the genus Hexamita and Spirillum Spironucleus. The authors identified five new species, Hexamitaguanqiaoensissp. Nov., Parasitized in Xenocyprismicrolepis Bleeker, Hexamitaliangzihuensissp. Nov., Parasitized in Xenocyprisdividi Leeker, ) And Spironucleus minutussp. Nov., Hexamitavarformissp. Nov. And Spironucleus glandularissp. Nov. Parasitized in Xenocyprisargentea Gönther. Six proteinaceous parasites in fish were studied by silver staining method.
