Rapid detection of carbapenemase genes by multiplex real-time PCR.
OBJECTIVES To develop a single multiplex real-time PCR assay to detect six different genetic types of carbapenemases already identified in Enterobacteriaceae (KPC, GES, NDM, IMP, VIM and OXA-48). METHODS A total of 58 bacterial isolates were tested. Thirty were previously characterized as resistant to carbapenems and documented by PCR and sequencing analysis to carry the following genes: bla(...
متن کاملDevelopment and evaluation of a real-time PCR assay for detection of Klebsiella pneumoniae carbapenemase genes.
We developed a novel real-time PCR assay to detect Klebsiella pneumoniae carbapenemases (KPCs) and used this assay to screen clinical isolates of K. pneumoniae and Klebsiella oxytoca for the presence of bla(KPC) genes. The TaqMan real-time PCR assay amplified a 399-bp product from the bla(KPC) gene. The amplicon was designed so that the genes for isoenzymes KPC-1, -2, and -3 could be easily dis...
متن کاملRapid detection of blaKPC carbapenemase genes by real-time PCR.
Carbapenem resistance among Enterobacteriaceae is an emerging problem worldwide. Klebsiella pneumoniae carbapenemase (bla(KPC)) enzymes are among the most common beta-lactamases described. In this study, we report the development and validation of a real-time PCR (q-PCR) assay for the detection of bla(KPC) genes using TaqMan chemistry. The q-PCR amplification of bla(KPC) DNA was linear over 7 l...

متن کاملMultiplex real-time PCR assay for detection and classification of Klebsiella pneumoniae carbapenemase gene (bla KPC) variants.
Carbapenem resistance mediated by plasmid-borne Klebsiella pneumoniae carbapenemases (KPC) is an emerging problem of significant clinical importance in Gram-negative bacteria. Multiple KPC gene variants (bla(KPC)) have been reported, with KPC-2 (bla(KPC-2)) and KPC-3 (bla(KPC-3)) associated with epidemic outbreaks in New York City and various international settings. Here, we describe the develo...
