Subtilase cytotoxin-encoding subAB operon found exclusively among Shiga toxin-producing Escherichia coli strains

Kinue Irino et al. J Clin Microbiol. 2010 Mar.

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).
