Klebsiella pneumoniaeisolates that produce carbapenemases (KPCs) are rapidly disseminating worldwide. To determine their genetic background, we investigated 16 blaKPC-2-harboring K. pneumoniae isolates from 5 countries. The isolates were multidrug resistant, possessed the blaKPC-2 gene, and differed by additional Beta-lactamase content. They harbored a naturally chromosome-encoded bla gene (bla...
Between 2014 and 2015, the Klebsiella pneumoniae carbapenemase (KPC) was becoming endemic in South Korea. To assess this period of transition, we analyzed KPC producers in terms of molecular epidemiology. A total of 362 KPC-producing Enterobacteriaceae strains, including one from 2013, 13 from 2014, and 348 from 2015, were actively collected from 60 hospitals throughout the peninsula. Subtypes ...
The emergence and rapid spread of antibiotic-resistant Klebsiella pneumoniae isolates harbouring the blaKPC gene that encodes for carbapenemase production have complicated the management of patient infections. This study in a tertiary care hospital in Egypt used real-time PCR assay to test ertapenem-nonsusceptible isolates of K. pneumoniae for the presence of the blaKPC gene and compared the re...
The emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP) co-carrying multiple carbapenemases is complicating clinical treatment. This study aimed to investigate the global dissemination trends CRKP strains that co-carry carbapenemases. isolate KP424 blaNDM-1 and blaKPC-2, recovered from a stool specimen, was identified by NG-Test Carba 5 test, genome sequence further determined using ...
Due to the lack of detailed reports of Klebsiella pneumoniae carbapenemase (KPC)-producing enterobacteria in Ontario, Canada, we perform a molecular characterization of KPC-producing Enterobacteriaceae submitted to the provincial reference laboratory from 2008 to 2011. Susceptibility profiles were accessed by E-test. Molecular types of isolates were determined by pulse-field gel electrophoresis...
Background :Nowadays beta lactamase-producing multiple-drug resistance Klebsiella pneumoniae is as an important factor in nosocomial infections which has produced therapeutic difficulties in worldwide. The purpose of this study was to identify KPC-producing K. pneumoniae (blakpc) in clinical samples in Iran. Materials and Methods: After identification of isolates in species level using cultura...
OBJECTIVE To evaluate ertapenem disk performance to predict Klebsiella pneumonie carbapenemase production by Gram-negative bacilli. METHODS All Gram-negative bacilli isolated between January 2010 and June 2011 were tested by disk diffusion (Oxoid™) for sensitivity to ertapenem, meropenem and imipenem. Resistant or intermediate sensitivity strains (diameter < 22 mm for ertapenem) were also tes...
We sequenced a novel conjugative blaKPC-2-harboring IncN plasmid, pYD626E, from an Escherichia coli sequence type 648 strain previously identified in Pittsburgh, Pennsylvania. pYD626E was 72,800 bp long and carried four β-lactamase genes, blaKPC-2, blaSHV-12, blaLAP-1, and blaTEM-1. In addition, it harbored qnrS1 (fluoroquinolone resistance) and dfrA14 (trimethoprim resistance). The plasmid pro...
Knowledge regarding the genomic structure of Enterobacter spp., the second most prevalent carbapenemase-producing Enterobacteriaceae, remains limited. Here we sequenced 97 clinical Enterobacter species isolates that were both carbapenem susceptible and resistant from various geographic regions to decipher the molecular origins of carbapenem resistance and to understand the changing phylogeny of...
Fifty-seven carbapenem-resistant Klebsiella pneumoniae isolates belonging to ST11 (50 isolates), ST423 (5 isolates), and two other sequence types were studied. All were positive for blaKPC-2, blaTEM-1, and blaCTX-M-14. SDS-PAGE analysis of six representative isolates demonstrated varied porin expression. Nevertheless, when blaKPC-2 was deleted, carbapenem resistance was markedly reduced. Additi...
