Distribution of blaTEM, blaSHV, and blaCTX-M genes among ESBL-producing P. aeruginosa isolated from Qazvin and Tehran hospitals, Iran
INTRODUCTION Pseudomonas aeruginosa is as an important opportunistic human pathogen, which is associated with several clinical infections that are usually difficult to treat because of resistance to multiple antimicrobials. The production of extendedspectrum ß-lactamases (ESBLs) is an important mechanism of ß-lactam resistance. The aims of this study were to determine the prevalence of ESBLs, a...
متن کاملMolecular epidemiology of carbapenem- resistant Enterobacteriaceae from a North Indian Tertiary Hospital
5 Abstract Aim: To analyse the occurrence of bla genes (blaIMP, blaVIM, blaGIM, blaSIM, blaSPM, blaPER, blaKPC, and blaOXA) responsible for carbapenemresistance, as well as the presence of cephalosporin-resistance genes (blaCTX-M, blaTEM, blaSHV and blaampC ) by polymerase chain reactions (PCRs). Methods: The study was performed on routine samples subjected to culture and antibiotics susceptibi...
متن کاملdistribution of blatem, blashv and blactx-m genes among escherichia coli isolates causing urinary tract infection in children
background emerging antibacterial resistance rates and extended-spectrum-β-lactamase producing escherichia coli recovered from urinary tract infections (uti) is an increasing problem in different regions, limiting therapeutic options. objectives the aim of this study was the detection of blatem, blashv and blactx-m genes among escherichia coli strains causing urinary tract infection in children...
متن کاملGenetic properties of blaCTX-M and blaPER β-lactamase genes in clinical isolates of Enterobacteriaceae by polymerase chain reaction
Objective(s):blaCTX-Mand blaPER are two genes that encode class A extended-spectrum β-lactamases (ESBLs) and can be responsible for therapeutic problems. This study was carried out to evaluate the molecular properties of these genes in clinical isolates of Enterobacteriaceae by polymerase chain reaction (PCR), restriction digestion and sequencing. Materials and Methods: During six months, start...
متن کاملUltrastructural Changes in Clinical and Microbiota Isolates of Klebsiella pneumoniae Carriers of Genes blaSHV, blaTEM, blaCTX-M, or blaKPC When Subject to β-Lactam Antibiotics
The aim of this study was to characterize the ultrastructural effects caused by β-lactam antibiotics in Klebsiella pneumoniae isolates. Three K. pneumoniae clinical isolates were selected for the study with resistance profiles for third-generation cephalosporins, aztreonam, and/or imipenem and with different resistance genes for extended-spectrum β-lactamases (ESBL) or Klebsiella pneumoniae car...
