characterization of extended-spectrum beta-lactamase (esbl)-producing kuwait and uk strains identified by the vitek system, and subsequent comparison of the vitek system with other commercial esbl-testing systems using these strains.two hundred and fifty-one unique patient isolates of klebsiella pneumoniae (123), escherichia coli (114), klebsiella oxytoca (7), enterobacter cloacae (5) and citrobacter freundii (2), flagged as extended-spectrum beta-lactamase (esbl) positive by the vitek system (gns-526 card), were collected. these strains were isolated from a variety of clinical specimens submitted to the clinical bacteriology laboratories of the royal infirmary of edinburgh (rie), edinburgh, uk (and associated gp practices) ...200616533989
molecular characterisation and diversity in enterobacter cloacae from edinburgh and egypt carrying bla(ctx-m-14) and bla(vim-4) β-lactamase genes.the purpose of this study was to compare the carbapenemases and extended-spectrum β-lactamases (esbls) associated with resistance, the genetic environment of these genes, and their location on plasmids among enterobacter cloacae isolates from edinburgh (uk) and egypt. nine e. cloacae isolates were obtained from egypt (n=3) and edinburgh (n=6). antimicrobial susceptibility testing was performed by agar dilution. molecular detection of carbapenemase genes, blactx-m-14 and the presence of integron ...201323622881
