This paper reports two different enterotoxigenic classes of the genus Aeromonas isolated from fishes. Strains of A. sobria were isolated from healthy fishes only wheras strains of A. hydrophila were isolated from both healthy and moribund fishes. Aeromonas sobria and hydrophilia strains produced a cytotoxic factor and were highly proteolytic. Seventy-five percent (75%) of the A. sobria strains produced only one type of hemolysis on 5% blood agar, but 92% of the A. hydrophilia produced two types of hemolysis. Enterotoxigenicity of all strains was tested by the rabbit gut loop technique and the suckling mouse test. Most of those Aeromonads were enterotoxigenic. Enterotoxigenic strains appeared to produce two different enterotoxins which were antigenically related, but they seemed to have different mechanisms of action. Enterotoxins of Aeromonas were shown to be antigenically different from those of E. coli.
本文报道了从鱼类中分离出的两种不同产肠毒素类型的气单胞菌属。仅从健康鱼类中分离出温和气单胞菌菌株，而嗜水气单胞菌菌株则从健康和濒死鱼类中均有分离。温和气单胞菌和嗜水气单胞菌菌株产生一种细胞毒素因子，且具有高度蛋白水解活性。75%的温和气单胞菌菌株在5%血琼脂上仅产生一种溶血类型，但92%的嗜水气单胞菌产生两种溶血类型。所有菌株的产肠毒素性通过兔肠袢技术和乳鼠试验进行检测。大多数这些气单胞菌具有产肠毒素性。产肠毒素菌株似乎产生两种不同的肠毒素，它们在抗原上相关，但作用机制似乎不同。气单胞菌的肠毒素在抗原上与大肠杆菌的肠毒素不同。
