Abstract
Direct plating of simulated stool specimens on MacConkey agar (MCA) with 10-μg ertapenem, meropenem, and imipenem disks allowed the establishment of optimal zone diameters for the screening of carbapenem-resistant Gram-negative rods (CRGNR) of ≤24 mm (ertapenem), ≤34 mm (meropenem), and ≤32 mm (imipenem).
