中华鳖嗜水气单胞菌感染的病理学观察

Studies on pathology of infection of Aeromonas hydrophila in Trionyx sinensis

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．

One hundred and ten Trionyx sinensis infected by Aeromonas hydrophila and diagnosed by microbiology were studied by patho histological technique. The results showed that the pathological changes were acute septicuemia whose main pathological change was red neck. Postmortem examination revealed swelling and haemorrhagic in liver,kidney,serious haemorrhagic and edema in alimentary canal,haemorrhagic and necrosis in gill like tissue. Characterization of histologic lesions were haemorrhagic,haemolysis, cell of all main organs were destroyed widely, cell of liver were destroyed seriously, vacuolar degeneration,karyorrhexis karyolysis, only some reticular shelf was left. Pathogenesis of infection is also discussed in thesis.
