Abstract

Fourteen strains of Aeromonas veronii were isolated from salt and fresh water in Rio de Janeiro and investigated for the presence of virulence factors. Eleven (79%) A. veronii strains were positive for enterotoxin by the suckling-mouse test and thirteen (93%) produced hemolysin. Of the 13 A. veronii strains that produced hemolysin, seven were investigated for cytotoxin production using Vero cells as indicator cells and all of them were positive.

摘要

从里约热内卢的咸水和淡水中分离出14株维罗纳气单胞菌，并对其毒力因子的存在情况进行了调查。通过乳鼠试验，11株（79%）维罗纳气单胞菌菌株的肠毒素呈阳性，13株（93%）产生溶血素。在13株产生溶血素的维罗纳气单胞菌菌株中，7株以Vero细胞作为指示细胞进行细胞毒素产生情况的调查，结果均呈阳性。
