Abstract

An elevated level of Shiga-like toxin I (SLT-I) production was found in 1 of 466 Escherichia coli strains studied. Among the 34 sonic lysates obtained from classical enteropathogenic E. coli, 5 produced SLT-I. The Aeromonas, Citrobacter, Edwardsiella, Enterobacter, Klebsiella, Proteus, Providencia, Pseudomonas, Salmonella, Serratia, Shigella, Yersinia, and Vibrio strains also studied were not SLT producers, except for a Shigella dysenteriae type 1 strain. Although SLT-I-producing E. coli strains were isolated from diarrhea, they seem to be an uncommon cause of disease in children less than 1 year old in our community.

摘要

在所研究的466株大肠杆菌中,发现1株产生的志贺样毒素I(SLT-I)水平升高。从典型致病性大肠杆菌获得的34份超声裂解物中,有5份产生SLT-I。所研究的气单胞菌、柠檬酸杆菌、爱德华氏菌、肠杆菌、克雷伯菌、变形杆菌、普罗威登斯菌、假单胞菌、沙门氏菌、沙雷氏菌、志贺氏菌、耶尔森氏菌和弧菌菌株,除1株痢疾志贺氏菌1型菌株外,均不产生SLT。虽然从腹泻患者中分离出了产生SLT-I的大肠杆菌菌株,但在我们社区1岁以下儿童中,它们似乎并非常见的致病原因。
