摘要： 对剑尾鱼感染嗜水气单胞菌的病理变化进行了全面细致的观察。结果显示：剑尾鱼感染发病呈急性过程，感染后10～15h为发病死亡高峰期；病理组织学变化以全身溶血性贫血和广泛的组织细胞变性、坏死为主；感染发病死亡时间主要集中在5～24h，感染部位和鳃最先受到损伤，最终因各器官结构破坏、功能衰竭和窒息而亡。

Abstract:Pathological changes of Xiphophorus helleri infected with Aeromonas hydrophila were observed completely in this study. The results were as follows. Infection outbreak was an impatient process, and the peak time of death was at 10-15h postinfection. Histopathological changes were characterized by general hemolytic anemia, extensive cellular degeneration and necrosis. Cardinal symptoms and pathological changes came about from 5 to 24h postinfection. Injection sites and gills were damaged initially. Finally the infected animals died because of organic structure breakage, function adynamia and asphxia.

Key words: Xiphophorus helleri； Aeromonas hydrophila； pathological change
