Abstract
Thirty-eight Escherichia coli strains belonging to 14 human enteropathogenic serogroups were isolated from 33 of 208 water samples studied. No virulence factor or virulence-related gene sequences were found in any of the 38 strains analyzed. The results point out the importance of detecting specific virulence factors before incriminating water as a source of human diarrhea.
摘要
从208份水样中的33份中分离出38株属于14种人类肠道致病血清群的大肠杆菌菌株。在所分析的38株菌株中均未发现毒力因子或毒力相关基因序列。结果指出在将水认定为人类腹泻来源之前检测特定毒力因子的重要性。
