【摘要】 报道鳜（Ｓｉｎｉｐｅｒｃａ ｃｈｕａｔｓｉ） 由柱状屈挠杆菌（ Ｆｌｅｘｉｂａｃｔｅｒ ｃｏｌｕｍｎａｒｉｓ） 引起的烂鳃病的病理研究结果－ 病鱼的组织病变可分为慢性和急性两种类型－ 鳃组织的病理变化，经过炎性水肿、细胞增生和坏死３ 个进程－ 慢性型以增生为主－ 急性型的鳃组织病变，由于病程短，炎性水肿迅速转入坏死，增生不严重或者几乎不出现，以炎性水肿和坏死为主－ 在鳃组织病变严重时，肝脏、肾脏也发生病变－肝细胞发生颗粒变性、水样变性；肾组织主要发生肾小管上皮细胞与基底膜分离，有些上皮细胞变性，甚至坏死－更多还原

【Abstract】 The pathological results of rotted gill disease in mandarinfish by Flexibacter columnaris are reported in this paper. There are two types of histopathological changes:chronic and acuteness. The gill tissue of the chronic generally undergoes three worsening steps, i.e. inflammatory edema, hyperplasia and necrosis. However, the acute one only passes through two steps: edema and necrosis. The liver and kidney of the diseased fish also show histopathological changes. The granular denaturation and vacuslation occur in liver cells.Epithelial cells in the renal tubule separated from basal membrane. Some epithelial cells are denaturated and necrosis.更多还原
