Mild Illness during Outbreak of Shiga Toxin-Producing Escherichia coli O157 Infections Associated with Agricultural Show, Australia

Bhakti R Vasant et al. Emerg Infect Dis. 2017 Oct.

Abstract

During a large outbreak of Shiga toxin-producing Escherichia coli illness associated with an agricultural show in Australia, we used whole-genome sequencing to detect an IS1203v insertion in the Shiga toxin 2c subunit A gene of Shiga toxin-producing E. coli. Our study showed that clinical illness was mild, and hemolytic uremic syndrome was not detected.

Keywords: Australia; Brisbane; Escherichia coli; HUS; STEC; Shiga toxin; Shiga toxin−producing E. coli; agricultural show; bacteria; hemolytic uremic syndrome; illness; infections; outbreak; whole-genome sequencing.
