Eleven isolates of Aeromonas species from human stool cultures were found to produce enterotoxin activity as determined by assay of culture filtrates in rabbit intestinal loops and rabbit skin and on adrenal Y1 cells. Hemolysin(s) and a cytotoxic protein were found to interfere in all three assay systems but could be inactivated upon heating at 56 degrees C or by specific antihemolysin. Biotyping of each isolate was performed with a conventional test system and with API 50E and APIZYM kit systems (Analytab, Inc.). No single test of the more than 70 biochemical reactions investigated was found to correlate with enterotoxigenicity in the strains of Aeromonas hydrophila examined. All strains were found to belong to ideal phenotypes of A. hydrophila, but each strain possessed its own biochemical profile.
通过兔肠袢、兔皮肤及肾上腺Y1细胞对培养滤液进行检测,发现从人类粪便培养物中分离出的11株气单胞菌属菌株可产生肠毒素活性。溶血素和一种细胞毒性蛋白在所有三种检测系统中均有干扰作用,但在56℃加热或使用特异性抗溶血素后可失活。使用传统检测系统以及API 50E和APIZYM试剂盒系统(Analytab公司)对每株分离菌进行生物分型。在所检测的70多种生化反应中,未发现任何单一检测与嗜水气单胞菌菌株的产肠毒素性相关。所有菌株均属于嗜水气单胞菌的理想表型,但每个菌株都有其自身的生化特征。
