气单胞菌科细菌广泛存在于各种自然水体中,同时与人类多种传染病有关。尽管已知它们可以产生多种胞外毒素,如细胞毒素、肠毒素等,但是关于它们的毒性机制仍未确定。为了解在腹泻病人中流行的菌株是否以带毒菌株占优势,作者对孟加拉国69名腹泻患者、11名健康对照人群以及40份地面水样分离到的120株气单胞菌的特征进行分析和比较。利用脂肪酸甲酯(FAME)特征对杂交群(HGs)作分析,用新近发展的基因指纹方法(AFLP)、生化表型分型系统(PhP)以及测定细菌溶血素和细胞毒素的产生等进行分析。
Aeromonas bacteria widely exist in a variety of natural water, at the same time with a variety of human infectious diseases. Although they are known to produce a wide variety of extracellular toxins, such as cytotoxins, enterotoxins and the like, the mechanisms of their toxicity have not been established. In order to determine whether predominant bacterial strains are predominant in patients with diarrhea, the authors analyzed the characteristics of 120 Aeromonas isolates isolated from 69 diarrhea patients, 11 healthy controls, and 40 surface water samples from Bangladesh And compare. The hybrids (HGs) were analyzed by using fatty acid methyl ester (FAME) and analyzed by newly developed gene fingerprinting (AFLP), biochemical phenotyping system (PhP) and determination of bacterial hemolysin and cytotoxin .
