Mucus-Activatable Shiga Toxin Genotype stx2d in Escherichia coli O157:H7

Abstract

We identified the mucus-activatable Shiga toxin genotype stx2d in the most common hemolytic uremic syndrome–associated Escherichia coli serotype, O157:H7. stx2d was detected in a strain isolated from a 2-year-old boy with bloody diarrhea in Spain, and whole-genome sequencing was used to confirm and fully characterize the strain.
