Abstract

Shiga toxin-producing Escherichia coli (STEC) O26:H11 is one of the most frequent pathogens associated with diarrhea and hemolytic-uremic syndrome (HUS). In this report, we present the draft genome sequences of seven strains of STEC O26:H11 carrying the stx2a or stx2d gene only and isolated in France from HUS patients.

Highlights

  • Shiga toxin-producing Escherichia coli (STEC) O26:H11 is one of the most frequent pathogens associated with diarrhea and hemolytic-uremic syndrome (HUS)

  • Among Shiga toxin-producing Escherichia coli (STEC) isolates, serotype O26:H11 is the second most frequently associated with severe human diseases worldwide, after O157:H7 [1, 2]

  • In a previous study [6], we analyzed 23 STEC O26 strains carrying the stx2 gene only, which were isolated in France between 2010 and 2013 from hemolytic-uremic syndrome (HUS) patients

Summary

Introduction

Shiga toxin-producing Escherichia coli (STEC) O26:H11 is one of the most frequent pathogens associated with diarrhea and hemolytic-uremic syndrome (HUS). Among Shiga toxin-producing Escherichia coli (STEC) isolates, serotype O26:H11 is the second most frequently associated with severe human diseases worldwide, after O157:H7 [1, 2]. Strains of STEC O26:H11 usually harbor the stx1a gene only or in combination with stx2a. In the 1990s, a new clonal subgroup of STEC O26 emerged that carries the stx2a gene alone [3].
