Prevalence and Molecular Characterization of Plasmid-mediated Extended-Spectrum β-Lactamase Genes (balaTEM, blaCTX and blASHV) Among Urinary Escherichia coli Clinical Isolates in Mashhad, Iran
Objective(s) Extended-spectrum beta-lactamase (ESBL) producing bacteria have an important role in nosocomial infections. Due to the limited availability of information about the molecular epidemiology of ESBL producing bacteria in Mashhad, we decided to investigate about TEM, CTX and SHV ESBLs among urinary Escherichia coli isolates in Mashhad, a city in northeast Iran. Materials and Methods ...
متن کاملPrevalence 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)...
متن کاملhigh prevalence of blactx-m-1 group extended-spectrum β-lactamase genes in escherichia coli isolates from tehran
conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...
متن کاملIdentification of extended-spectrum β-lactamase genes in Escherichia coli isolated from patients with urinary tract infection
Introduction: Recentlly, resistance to antibiotics has increased and antibiotic-resistant strains producing extended-spectrum beta-lactamases (ESBLs) have emerged among Enterobacteriaceae, mainly in Escherichia coli (E. coli). In this study we aimed to determine phenotypic and genotypic ESBL production in isolated E. coli from women with urinary tract infection (UTI). Materials and Methods: In...
متن کاملPrevalence of qnr Genes in Extended-Spectrum β-Lactamase Producing Klebsiella pneumoniae Isolated from Clinical Urine Specimens in University Teaching Hospitals, Iran
Background and Aims: Extended-spectrum β-lactamase (ESBL) producing gram negative bacteria are resistant to penicillins, narrow and extended-spectrum cephalosporins, and aztreonam; also they are frequently resistant to trimethoprim-sulfamethoxazole, aminoglycosides, and quinolones. This study aimed to investigate the prevalence of plasmid-mediated quinolone resistance (PMQR) determinants q...
