| 摘 要： | 在光镜水平下研究了刺激隐核虫寄生黄鳍鲷和真鲷后引起宿主组织病理学的变化。该寄生虫可在宿主皮肤、鳃上皮和舌上皮的组织内寄生。与正常组织相比,被寄生的皮肤表皮层明显增厚、粗糙,其增厚部分主要是粘液细胞层、表皮层与真皮层间的联系被破坏。寄生囊内有较大的空隙。虫体内含有大量的宿主细胞残骸。由于寄生虫的感染,使得非寄生部位的脏器也出现某些病理变化:肝细胞萎缩,窦状隙增大;脾肾内都有颗粒性沉积。本研究结果还与淡水“白点”病引起的病理组织学变化进行了比较。

| Abstract: | The microscopical histopathology of 'white spot'disease in marine fish is studied in Sparus latus and Pagrosomus major. The pathogen is Cryptocaryon irritans. This parasite can parasitize the epitheleal tissues of skin, gill and tongue of the hosts. Compared with normal tissues, the epidermis of infected host skin become thick and rough obviously. The proliferation of skin is in the layer of mucous cells. The combination between epidermis and derma is highly damaged in the hosts. There is a gap around parasite forming cyst-like protrusion. There are large number of host cells not completely digested. After being infected, the viscera which though no parasites are found also show certain pathological changes: The hepatocytes are atrophied and sinusoidal spaces are abnormally wide; in the spleen and kidney, there are depositions of pellets. The results of our research is compared with that of freshwater fish 'Ich'which is most closely related with the disease here studied. |
