Schematic illustrating model of the stepwise evolution of STEC O157. The proposed stepwise evolution model of STEC O157 was schematically illustrated according to previous reports (8,9). Clonal complexes (CCs) A1 to A6 are indicated, along with phenotypic changes, antigen shifts, and acquisitions of Stx phages and pO157. Squares indicate contemporary circulating STEC O157 clones. EPEC, enteropathogenic E. coli; GP, β-glucuronidase–positive; NSF, non–sorbitol-fermenting; SF, sorbitol-fermenting;
