Detection of the emerging Shiga toxin-producing Escherichia coli O26: H11/H- sequence type 29 (ST29) clone in human patients and healthy cattle in Switzerland

Abstract

Shiga toxin-producing Escherichia coli O26:H11/H- strains showing the characteristics of the emerging human-pathogenic ST29 clone (stx2a+ only, eae+, plasmid gene profile hlyA+ etpD+) were detected from human patients and healthy cattle, indicating a possible reservoir. Sheep also appear to shed strains related to the new pathogenic clone O26:H11/H- (ST29, stx1a+ only, eae+, plasmid gene profile hlyA+ etpD+). © 2013, American Society for Microbiology.
