Direct Detection of Carbapenem-Resistant Organisms from Environmental Samples Using the GeneXpert Molecular Diagnostic System

ABSTRACT In this pilot study, traditional culture and PCR methods were compared to the Cepheid GeneXpert IV molecular diagnostic system with the Xpert Carba-R assay (Carba-R assay) for detection of carbapenem resistance genes in primary environmental samples collected during a health care-related ou...
