In addition to the large virulence plasmid pO157, a novel 38-kb conjugative plasmid, pO157_Sal, was identified and sequenced from an Escherichia coli O157:H7 outbreak-associated Chinese isolate that shares high similarity with a plasmid in Salmonella enterica serovar Agona. The plasmid was found in 15 of 326 isolates, 12 of which were of the same pulsed-field gel electrophoresis type.
此外,从一株与肠出血性大肠杆菌 O157:H7 爆发相关的中国分离株中还鉴定和测序了一个新型 38kb 可接合质粒 pO157_Sal,该质粒与肠炎沙门氏菌血清型 Agona 中的一个质粒具有高度相似性。该质粒在 326 个分离株中发现了 15 个,其中 12 个为相同的脉冲场凝胶电泳型。
