Direct Detection of Carbapenem-Resistant Organisms from Environmental Samples Using the GeneXpert Molecular Diagnostic System
Use of the Carba-R assay for detection of carbapenem-resistant Gram-negative organisms (CROs) can provide data for implementation of a rapid infection control response to minimize the spread of CROs in the health care setting.In this pilot study, traditional culture and PCR methods were compared to...

Use of the Carba-R assay for detection of carbapenem-resistant Gram-negative organisms (CROs) can provide data for implementation of a rapid infection control response to minimize the spread of CROs in the health care setting.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 outbreak. Overall, traditional culture-dependent PCR and the Carba-R assay demonstrated 75% agreement. The Carba-R assay detected carbapenemase genes in five additional samples and in two samples that had additional genes when compared to culture-dependent PCR. The Carba-R assay could be useful for prioritizing further testing of environmental samples during health care-related outbreaks. |
