Abstract

More than 90% of the strains of Escherichia coli O157:H7 that were identified on a MicroScan gram-negative dried conventional (overnight) panel gave one of two unique biochemical profile numbers that were not detected in other d-sorbitol-negative E. coli or in other strains isolated from pathogenic processes. This suggests that the panel has the capability of being used as a preliminary screening tool for O157:H7 strains involved in hemorrhagic colitis when MacConkey-sorbitol agar is not available.
