Prevalence of Extended-Spectrum β-Lactamases Genes in Clinical Isolates of Pseudomonas aeruginosa
ABSTRACT Background and Objectives: Pseudomonas aeruginosa is an opportunistic pathogen resistant to various antibiotics. The aim of the present study was to study resistant patterns in clinical isolates of P. aeruginosa, classify them into pandrug resistance (PDR), extensive drug resistance (XDR) and multidrug resistance (MDR)...

www.expert-reviews.com ISSN 1478-7210 © 2008 Expert Reviews Ltd 10.1586/14787210.6.5.671 The potential options available for treating serious infections caused by enterobacteria include penicillins (with or without β-lactamase inhibitors), cephalosporins, aztreonam, carbapenems, fluoroquinolones and, in certain situations only, aminoglycosides and colistin. Recently, tigecycline has been added ...
متن کاملIdentification and characterization of ceftriaxone resistance and extended-spectrum beta-lactamases in Malawian bacteraemic Enterobacteriaceae.
OBJECTIVES To enumerate and characterize extended-spectrum beta-lactamases (ESBLs) amongst ceftriaxone-resistant coliforms in Blantyre, Malawi, where third-generation cephalosporin use is currently highly restricted. METHODS Over the period April 2004-March 2005 all ceftriaxone-resistant isolates from blood cultures were examined for the presence of ESBLs. Isoelectric focusing was performed o...
متن کاملdetection of extended-spectrum β-lactamases (esbls) in escherichia coli
background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...
متن کامل[The widening challenge of extended spectrum β-lactamases].
Since 1980, the prescription of new semi-synthetic molecules of third generation cephalosporins changed the course of modern medicine. However, the acquired resistance against these antibiotics was rapidly developed with the production of extended spectrum β-lactamases (ESBL) (TEM and SHV types) disseminated mainly by nosocomial Klebsiella pneumoniae clones. Since around 2000, we are facing a w...
