通过微生物方法确定为嗜水气单胞菌感染的１１０例中华鳖自然病例，采用病理学方法进行研究．结果表明：以鳖红脖子为主的急性败血症病型，其肉眼病变以肝和肾肿大、出血，消化道严重出血、水肿，鳃状组织出血、坏死为主要变化；显微病变以全身各主要器官的细胞广泛性破坏，出血，溶血为特征；实质器官中以肝细胞被破坏最为严重，表现肝细胞空泡变性，细胞破碎、消失，有的只剩下肝组织结构的网状支架．文中还结合观察结果对中华鳖嗜水气单胞菌感染的发病机理进行了探讨
110 cases of natural turtles treated by Aeromonas hydrophila were identified by the method of microbiology, and pathological methods were used to study them. The results showed that the main pathological changes of acute septicemia with turtle red neck were liver and kidney enlargement, hemorrhage, severe gastrointestinal bleeding, edema, gill bleeding and necrosis. The main organs of the cells widespread destruction, hemorrhage, hemolysis is characterized by the destruction of liver cells in the most serious organs, the performance of hepatocyte vacuolar degeneration, cell disruption, disappear, and some only the liver tissue structure of the mesh stent. In this paper, the pathogenesis of Aeromonas hydrophila infection in Chinese soft-shelled turtle
