Isogenic strain of Escherichia coli O157:H7 that has lost both Shiga toxin 1 and 2 genes.

Clinical and diagnostic laboratory immunology - 1 Jul 2001

Abstract excerpt

An Escherichia coli O157:H7 strain isolated from a patient with hemorrhagic colitis was found to exhibit two slightly different colony morphology types on differential medium. Each morphological type, designated TT12A and TT12B, was isolated, and serological testing using various assays confirmed that both strains carried the O157 and the H7 antigens. Biochemical testing showed that the strains had identical...
