Culture on cefixime, tellurite, and sorbitol-MacConkey agar after HCl treat
ment facilitated the growth of 410 (94%) of 436 eae-positiue Shiga toxin-pr
oducing Escherichia coli (STEC) strains and 17 (16%) of 107 eae-negative ST
EC strains. This selectivity was closely related to acid resistance in E. c
oli and tellurite resistance in eae-positive STEC strains.
