Abstract

Strains of Aeromonas hydrophila isolated from skin infections of common freshwater fish in Bangladesh were tested for enterotoxin production, hemolysin production, and any correlation between these two activities. We also tested the resistance patterns of A. hydrophila to different drugs, especially in relation to ampicillin. The A. hydrophila strains produced an enterotoxin that was related to their beta-hemolytic activities. Production of beta-hemolysin may thus be an indicator of enterotoxicity. As 50% of the strains of A. hydrophila were found to be susceptible to 12.5 micrograms of ampicillin per ml, media containing this antibiotic may not be suitable for their isolation.

摘要

对从孟加拉国常见淡水鱼皮肤感染中分离出的嗜水气单胞菌菌株进行了肠毒素产生、溶血素产生以及这两种活性之间相关性的检测。我们还检测了嗜水气单胞菌对不同药物的耐药模式,特别是与氨苄西林相关的耐药模式。嗜水气单胞菌菌株产生了一种与其β-溶血活性相关的肠毒素。因此,β-溶血素的产生可能是肠毒性的一个指标。由于发现50%的嗜水气单胞菌菌株对每毫升12.5微克的氨苄西林敏感,含有这种抗生素的培养基可能不适合用于它们的分离。
