摘要
本文报告对检自腹泻患者粪便的三种60株气单胞菌进行了致病性实验研究。结果55株(91.67％)检出一种以上致病因子,其中38株(63.33％)检出肠毒素;39株(65.00％)检出细胞毒素;28株(46.6％)产生溶血素;45株(75.00％)对小白鼠有很强的致死毒性。实验结果证实气单胞菌能产生多种致病因子,亲水和温和气单胞两个种较豚鼠气单胞菌致病力强,是人类腹泻的重要病原菌之一。
We carried out a laboratory research on the pathogenesis of 60 strains of three species of Aeromonas which were isolated from patients with diarrhea. It was found that one or more pathogenetic factors harbored in 56 strains, among them enterotoxin in 38 strains (63.33%), cytotoxin in 39 strains (65. 00%), hemolysin in 28 strains and lethal factors to white mice in 45 strains (75. 00%). The results proved that Aeromonas which could produce several pathogenetic factors was one of the important diarrheal pathogens and the pathogenesis of A. hydrophita and A. sobria was stronger than that of A. caviae.
