To determine the origin of >4,000 suspected diarrheagenic Escherichia coli strains isolated during 2004-2011 in South Africa, we identified 7 isolates as serotype O104; 5 as enteroaggregative E. coli O104:H4, and 2 as enteropathogenic E. coli O104:non-H4. Pulsed-field gel electrophoresis showed that these isolates were unrelated to the 2011 E. coli O104:H4 outbreak strain from Germany.
为了确定在 2004 年至 2011 年期间南非分离的 >4000 株疑似致泻性大肠杆菌菌株的来源,我们鉴定出 7 株血清型为 O104 的菌株;5 株为聚集性大肠杆菌 O104:H4,2 株为肠致病性大肠杆菌 O104:非 H4。脉冲场凝胶电泳显示,这些分离株与 2011 年德国大肠杆菌 O104:H4 暴发菌株无关。
