从天然感染的卵圆鲳(Trachinotus blochii)分离到1株刺激隐核虫(Cryptocaryon irritans),再经人工感染的方法收集各期虫体,制成电镜样品,对虫体进行超微结构研究。刺激隐核虫质膜的基本结构与淡水的多子小瓜虫的质膜相似,分为3层:外限制膜、外胞膜和内胞膜。刺激隐核虫的质膜小泡内充满大量电子致密物质(EDM)。幼虫、幼体和滋养体均具有复杂的口器,由胞咽、口肋、双动基体口纤毛和线带等组成,但不具备膜口类纤毛虫所具有的独特的细胞器:Lieberkuhn氏器。单动基体的体纤毛存在于幼虫、幼体和滋养体,但在包囊期,体纤毛和口器消失。各期虫体的胞质中具有线粒体、高尔基体和脂肪体等细胞器,有的阶段具有粘液囊、伸缩泡、食物泡、共生细菌等。粘液囊在大小、形态和分布上与多子小瓜虫的不同。文中分析了刺激隐核虫在形态上与多子小瓜虫的诸多差异,认为刺激隐核虫的分类更适合归于原口类(Promotome),而不是膜口类(Ophryoglenina)。
One strain of Cryptocaryon irritans was isolated from the naturally infected Trachinotus blochii, and then collected by electron microscopy after being infected by artificial infection. The ultrastructure of the parasites was studied. The basic structure of Caenorhabditis elegans membrane is similar to the plasma membrane of freshwater multifamily Cucumber, which is divided into three layers: outer limiting membrane, outer membrane and inner membrane. The plasma membrane vesicles that stimulate Cryptocarya are filled with a large number of electron-dense substances (EDMs). Larvae, larvae and trophozoites all have complex mouthparts, which consist of the oropharyngeal fossa, mouth fossa, double-acting cilia and cords of the mouth, but do not possess the unique organelles of the Mycoplasma ciliate: Lieberkuns. A single moving body of the body cilia present in larvae, larvae and trophozoites, but in the cysts, body cilia and mouth disappear. Each stage of the body of cytoplasm with mitochondria, Golgi and fatty body and other organelles, and some stages with mucus sac, stretching bubbles, food bubbles, symbiotic bacteria. Mucosa in the size, shape and distribution and more than a small melon insects different. In this paper, we analyzed the many differences in the morphology of the Cryptocaryon spermatophila from the multi-calamus, and suggested that the classification of the Cryptocaryon irritant is more suitable for the promoter, rather than Ophryoglenina.
