Abstract
Escherichia coli O104 isolates collected from different sources in the United States were examined for virulence genes typical of enterohemorrhagic E. coli and those identified in the O104:H4 isolate associated with the 2011 German outbreak. The unexpected presence of virulence markers in these isolates highlights the importance of screening unusual and potentially pathogenic Shiga toxin-producing E. coli serotypes.
摘要
从美国不同来源采集的大肠杆菌 O104 分离株被检测了肠出血性大肠杆菌的典型毒力基因和与 2011 年德国暴发相关的 O104:H4 分离株中的毒力基因。这些分离株中存在意外的毒力标志物，突出了筛选不常见的和潜在致病性产志贺毒素大肠杆菌血清型的重要性。
