AmpC β lactamases in Urinary Klebsiella pneumoniae Isolates: First Report of ACC Type AmpC β-lactamase Resistance in Iran
Background & Objective: The production of plasmid-mediated AmpC beta-lactamases (PMABLs) among urinary Klebsiella pneumoniae isolates causes a severe problem to the successful treatment of urinary tract infections (UTIs). This study was designed to evaluate antimicrobial resistance, the presence of AmpC beta-lactamase genes, and the genetic relatedness among K. pneumoniae strains separated from...
متن کاملPrevalence of blaCTX-M Gene among Extended- Spectrum β-Lactamases Producing Klebsiella pneumoniae Clinical Isolates in Iran: A Meta-Analysis
Background: CTX-M-type extended-spectrum β-lactamases (ESBLs) are the most prevalent ESBLs in bacterial members of Enterobacteriaceae family including Klebsiella pneumoniae. The global spread of CTX-M-producing K. pneumoniae is a major concern in most countries including Iran. The aim of this meta-analysis was to determine the relative frequency (RF) of blaCTX-M gene among ESBLs-producing K. pn...
متن کاملDetection of CTX-M-β Lactamases form Isolated Klebsiella pneumoniae
Background and Objective: Organisms producing CTX-M β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. However, the laboratory detection of these strains is not well defined. In this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of CTX-M β-lact...

متن کاملcharacterization of ampc, ctx-m and mbls types of β-lactamases in clinical isolates of klebsiella pneumoniae and escherichia coli producing extended spectrum β-lactamases in kerman, iran
background: extended spectrum β-lactamases (esbls) and ampc β-lactamases enzyme are major sources of resistance to β-lactam antibiotics especially in enterobacteriaceae such as escherichia coli and klebsiella pneumoniae. increasing frequency of the co-existence of esbls with ampc-β-lactamases in bacteria is a serious threat for treating bacterial infections. conclusions: outbreak of isolates co...
