Methods A total of 22 isolates, K. pneumoniae (n=20), Escherichia coli (n=1) and Enterobacter aerogenes (n=1), were collected from a university hospital, in Lisbon, Portugal. MIC were determined by Etest and interpreted according to Clinical and Laboratory Standards Institute guidelines. PCR was performed with primers designed to amplify blaSHV, blaTEM and blaKPC genes. Molecular typing was per...

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...

conclusions our data showed that, the high prevalence of beta-lactamase genes among isolates, and it. our findings may provide useful insights in replace of the appropriate antibiotics and it may also prevents of esbls, mediated resistance problem. results from 145 strains of e. coli, 51(35.2%) and 61(42.1%) isolates were resistance to ceftazidime and cefotaxime, respectively. esbl production w...

resistance to oxyimino cephalosporins antibiotics in enterobacteriaceae is primarily done by the extended spectrum β-lactamases (esbls). clear identification of risk factors for esbl-producing infections is necessary. therefore, efficient strategies can be developed to decrease outbreak of these infections. the aim of this study was to determine the antibacterial susceptibility and esbls patter...

Introduction: Extended spectrum β-lactamases (ESBLs) are enzymes that degrade β-lactam antibiotics and have been reported to be an important cause of nosocomial infection in worldwide. Methods: During 2009, 659 enterobacteria strains were isolated from different clinical specimens and tested for ESBL production. The disk approximation test, combined disk method and addition of clavulanic acid w...
