1993年以来,从福建省莆田、福清及福州郊区甲鱼场发病中华鳖中分离、纯化和鉴定了54株气单孢菌。回归试验证实了该菌确为导致中华鳖病害的病原菌。对这些菌株的溶血素、内毒素和细胞毒素等致病因子进行了检测、比较和分析,显示该菌有溶血活力、内毒素和细胞毒素,但它们的毒素强弱与气单胞菌本身对小鼠的致死效应并不成正相关。
Since 1993, 54 strains of Aeromonas have been isolated, purified and identified from the Chinese soft-shelled turtle in the turtle farm in Putian, Fuqing, Fuzhou, Fujian Province. Regression test confirmed that the bacteria is indeed the pathogen causing soft-shelled turtle diseases. The pathogenicity factors such as hemolysin, endotoxin and cytotoxin of these strains were tested, compared and analyzed. The results showed that the bacteria had hemolysis activity, endotoxin and cytotoxin, but their toxins were strongly related to A. aeruginosa itself The lethal effect in mice is not positively related.
