本文对草鱼的隐鞭虫病、车轮虫病、小瓜虫病、指环虫病、三代虫病及中华鱼蚤病六种寄生虫性鳃病的组织病理变化进行比较研究。寄生虫性鳃病均可引起鳃组织发生炎症反应,粘液分泌亢进,嗜酸粒细胞和淋巴细胞浸润;但又因病原体的种类不同,危害鱼的方式、方法不同,因此病理变化又有很大差别,对鱼危害较大的均为变质性炎,如隐鞭虫病;对鱼危害较小的则属增生性炎,如中华鱼蚤病。 In this paper, we compared the histopathological changes of six parasite gill diseases, including Trichinella spiralis, Trichodina, Cucurbitaceae, Gynostemma, Third-generation and Western fish flea diseases. Parasitic gill disease can cause gill inflammation, mucus hypersecretion, eosinophils and lymphocyte infiltration; but because of the different types of pathogens, endangering the fish way, the method is different, so the pathological changes have a great Differences in fish are more harmful degenerative inflammation, such as whipwormosis; less harmful to fish is a proliferative inflammation, such as the Chinese flea disease.
