Some Escherichia coli produce Shiga toxin (Stx) in which cytotoxicity is increased (activated) by intestinal mucus and elastase (Stx2d(activatable)). These strains are highly virulent in mice, but their association with human disease is poorly understood. We investigated the prevalence of Stx2d(activatable) among Stx-producing E. coli (STEC) isolated from humans and the association between production of this Stx and the clinical outcome of infection.
