摘 要: 本文报道了一种由嗜水气单胞菌引起的鲤鱼穿孔病的病理学研究结果。该病的主要特征是最初在体表出现红斑,进而表皮及真皮坏死和崩解,肌肉溃烂形成大小不一的溃疡灶,最后体壁穿孔而病鱼死亡。病理组织学上主要表现为表皮细胞变性坏死,真皮充血、出血及炎性水肿和坏死,肌肉呈变质性炎,病程较长的可见肉芽组织增生及修补。鳃和心、肝、脾、肠、胰、肾等内脏器官呈现变性、充血和发炎等变化。 This paper reports the pathological changes about the Perforation Disease in Carp caused by Aeromonas hydrophila subsp. hydrophlia. The main lesions occurred on the outside of the affected fish bodies. Grossly, the changes were characterized by the ulcers and perforations on the body walls. The erythema appeared initially on the skin. Afterwards, the epidermis and dermis nectosised and crumbled. The skeletal muscle festered and formed ulcer focuses, At the last stage of the disease, the body walls with the ulcer were bored with a hole, and the diseased fish died of the perforation. Histopathologically,the epidermis cells swelled, degenerated, necrosised and crumbled. The demis showed hyperemia, hemorrhage,inflammatory edema and necrosis. Alterative inflammation occurred in the skeletal muscle, with the muscle fibres swelling, degenerating, necrosising and crumbling, and a large number of inflammtory leukocytes infiltrating among tie muscle tissue. In some cases whose courses of disease were longer, the granulation tissue regenerated and mended the damage in the focuses. The visceral organs such as heart, liver, spleen, pancreas, kidney, intestine and gill slowed hyperemia, degeneration and inflammation.
