Description

<jats:title>ABSTRACT</jats:title> <jats:p> Shiga toxigenic <jats:italic>Escherichia coli</jats:italic> (STEC) strains are a diverse group of organisms capable of causing severe gastrointestinal disease in humans. Within the STEC family, certain strains appear to have greater virulence for humans. STEC strains carrying <jats:italic>eae</jats:italic> and belonging to serogroup O157 or O111 have been responsible for the vast majority of outbreaks of STEC disease reported to date. Here we describe a STEC O113:H21 strain lacking <jats:italic>eae</jats:italic> that was responsible for a cluster of three cases of hemolytic-uremic syndrome. This strain produces a single Stx2-related toxin and adheres efficiently to Henle 407 cells. </jats:p>
