Selectively detect sorbitol negative Escherichia coli from clinical specimens with Thermo Scientific™ Remel™ MacConkey Agar with Sorbitol prepared media plates. The medium is recommended for the isolation of verotoxin-producing E.coli O157: H7. Unlike most serotypes of E.coli, verotoxin-producing E.coli O157: H7 does not ferment sorbitol and, therefore, produces colorless colonies. In contrast, most E.coli strains ferment sorbitol and form pink colonies.
Escherichia coli O157 is a significant human pathogen and is recognized as a cause of hemorrhagic colitis, an illness characterized by bloody diarrhea, severe abdominal pain, and hemolytic uremic syndrome.
Use Sorbitol MacConkey Agar for selective detection of Escherichia coli O157.
