摘要
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。
This paper deals with histopathological comparison of six gill diseasescaused by parasites in grass carp. These diseases are Cryptobiasis, Trichodiniasis,Ichthyophthiriasis, Dactylogyriasis, Gyrodactyliasis and Sinergasiliasis. Our observations bear out, all parasitic gill diseases are able to cause the inflam-matory reaction, the gill hyperfunctionally secrete mucus and the eosinophilic andlymphocytic infiltration. However, there are some obvious differences in these diseases caused by various parasites each other. The seriously harmful diseases are degenerativeinflammation, such as Cryptobiasis, and the slightly harmfu1 diseases are proliferativeinflammation, such as Sinergasiliasis.
