title: Improved selective and differential medium for isolation of Escherichia coli O157:H7.
abstract: GMAC, a modified version of Sorbitol MacConkey medium (SMAC), was produced with a reduced quantity of selective agents and incorporated gentiobiose. GMAC supported a higher recovery rate of heat- or acid-injured Escherichia coli O157:H7 cells than SMAC with cefixime and tellurite (CT-SMAC), while differentiating E. coli O157:H7 from sorbitol-nonfermenting Hafnia alvei.
