The increasing incidence of carbapenem nonsusceptibility among clinically important species is of global concern. Identification of the molecular mechanisms underlying carbapenem nonsusceptibility is critical for epidemiological investigations. In this report, we describe a real-time PCR-based assay capable of simultaneously detecting blaKPC and blaNDM, two of the most important carbapenemases, directly from culture in less than 90 min. The assay was validated with blaKPC- and blaNDM-carrying clinical isolates and demonstrated 100% concordance with the Carba NP test.
