Figure 1. . Representative results of the Carba NP test. The Carba NP test was performed with a noncarbapenemase producer (Escherichia coli producing the extended-spectrum β-lactamase CTX-M-15, upper panel) and with a carbapenemase producer (Klebsiella pneumoniae–producing New Delhi metallo-β-lactamase-1, lower panel) in a reaction medium without (left panel) and with (right panel) imipenem. Uninoculated wells are shown as controls. Photographs were taken after a 1.5-hour incubation.
