Abstract

The presence of subAB was investigated for 3,453 Escherichia coli strains of various pathogenic categories. The occurrence of other virulence genes in subAB-positive strains was investigated. The subAB operon was detected among some Shiga toxin-producing E. coli (STEC) serotypes devoid of eae and carrying ehxA. Most subAB-positive strains also harbored stx2, iha, saa, and lpfA(O113).

摘要

研究了来自各种致病类别的 3453 株大肠杆菌菌株中 subAB 的存在情况。研究了 subAB 阳性菌株中其他毒力基因的发生情况。在一些不携带 eae 但携带 ehxA 的产志贺毒素大肠杆菌 (STEC) 血清型中检测到 subAB 操纵子。大多数 subAB 阳性菌株还携带 stx2、iha、saa 和 lpfA(O113)。
