| 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～ 2 4h ,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 10-15 h 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 24 h post-infection. Injection sites and gills were damaged (initially.) Finally the infected animals died because of organic structure breakage, function adynamia and (asphxia.) |
| Keywords: | Xiphophorus helleri Aeromonas hydrophila pathological change |
