Abstract

We found two Shiga toxin producing Escherichia coli O157:H7 strains isolated from humans carrying the stx₁ gene with an IS1203-like element (designated as IS1203v₁). The IS1203v₁ was inserted into the coding region of the A subunit 7 bp upstream from the TGA termination codon, resulting in a loss of two amino acid residues (Ser-Ser) from its C terminus. Toxicity of the Stx1 was confirmed by Vero cell assay. IS1203v₁ hardly affected the stx₁ gene in either its expression or the toxicity of its product.
