鳖穿孔病是我国养鳖业的主要疾病之一，其发病对象主要是稚鳖。从垂死的鳖体中分离到Ｍ－Ⅱ－３、Ｍ－５、Ｍ－Ⅰ－３和Ｍ－Ⅱ－２四株细菌。经人工感染试验均对健康稚鳖表现出较强的致病力，出现与自然病鳖相同的症状。由此证实这四菌株是鳖穿孔病的病原菌。对菌体形态特征、培养特性和生理生化反应的鉴定证明致病菌为嗜水气单胞菌（Ａｅｒｏｍｏｎａｓｈｙｄｒｏｐｈｉａ）和普通变形菌（Ｐｒｏｔｅｕｓｕｕｌｇａｒｉｓ）。
Turtle perforation disease is one of the main diseases in our country to support the turtle industry, the incidence of the object is mainly juvenile turtle. Four strains M-Ⅱ-3, M-5, M-Ⅰ-3 and M-Ⅱ-2 were isolated from the dying turtle. The human infection test showed healthy virgin turtle showed strong virulence, with the same symptoms of natural disease turtle. This confirmed that these four strains of turtle perforation pathogenic bacteria. Identification of the morphological characteristics, culture characteristics and physiological and biochemical reactions showed that the pathogenic bacteria were Aeromonas hydrophila and Proteus uulgaris.
