CHROMOGENIC EC O157:H7 AGAR (as per ISO 16654)

Chromogenic EC 0157: H7 Agar Base is used for selective isolation and detection of Escherichia coli 0157: H7. Based on the virulence properties, different strains are divided into Enterotoxigenic (ETEC), Enteropathogenic (EPEC), Enteroinvasive (EIEC), Verotoxigenic (VTEC) and Enterohaemorrhagic (EHEC). Escherichia coli O157:H7 is an Enterohaemorrhagic strain implicated in foodborne illness. They are identified at laboratory scale by exploiting their unusual biochemical characters. This culture media is based on the formulation described by Rappaport and Henigh and uses a chromogenic mixture along with sorbitol for selective isolation of Escherichia coli O157:H7.
