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

摘要

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⁺).
