Abstract excerpt

Escherichia coli O157:H7 variants were examined for trait mutations and by molecular subtyping to better define clonal complexes postulated on the O157:H7 evolution model. Strains of beta-glucuronidase-positive, sorbitol-negative O157:H7 isolated in United States and Japan were identical to A5 clonal strain and shared sequence type (ST)-65 by multilocus sequence typing (MLST); thus, they belong in A5. However,...
