Mild Illness during Outbreak of Shiga Toxin−Producing<i>Escherichia coli</i>O157 Infections Associated with Agricultural Show, Australia

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.
