acumedia* MacConkey Agar with Sorbitol

• Intended Use: MacConkey Agar W/ Sorbitol is used for the isolation of pathogenic Escherichia coli.
• Product Summary and Explanation: MacConkey Agar W/ Sorbitol is based on the formula by Rappaport and Henig. Originally developed for isolating enteropathogenic (EPEC) serotypes, O11 and O55, this medium is recommended for the isolation and differentiation of enterohemorrhagic E. coli O157:H7. This organism causes hemorrhagic colitis, which results in bloody diarrhea and can lead to kidney failure and death. Serotype O157 has been implicated in serious foodborne diseases.
MacConkey Agar W/ Sorbitol contains sorbitol instead of lactose for differentiating enteropathogenic E. coli serotypes; these strains are typically sorbitol negative. MacConkey Agar W/ Sorbitol is recommended for clinical and food testing.
