conclusions according to our results, blatem-116 was the most frequent isolated esbl gene among the p. aeruginosa strains isolated from patients. results ciprofloxacin and piperacillin were the most efficient antipseudomonal agents. the results disclosed that 19 (16.37%) of the isolates were multidrug resistant and 8 (6.89%) were esbl-positive. of the 116 isolates, 30 (25.86%) were resistant to...
introduction: extended spectrum beta-lactamase (esbl) producing escherichia coli generate a major problem for clinical therapeutics and epidemiological study. the incidence of esbl producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. the aim of this study was to determine the a...
In the last decades, Extended-Spectrum-β-Lactamases (ESBLs) in gram negative bacilli have appeared as a significant mechanism of resistance to antibiotics. Although resistance to carbapenems is increasing among bacteria, they are still the treatment of choice for serious infections caused by ESBL producers. Therefore, the aim of the present study was to evaluate the effect of ß-lacta...
Background: The increasing use of β-lactam antibiotics in clinics for the treatment of different bacterial infections since early 1980s has led to increased rates of resistant bacteria isolated from patients. One of the problems in the treatment of nosocomial infections is related to resistant bacteria such as Enterobacter cloacae due to cross resistance through extended-spectrum beta-lactamase...
conclusions the results of this study phenotypically and genotypically confirmed the high frequency of esbl-producing strains, such as the ctx-m and ctx-m-1 genes, among enterobacteriaceae isolates in our region. therefore, use of antibiotic susceptibility testing for the detection of esbl isolates prior to the prescription of beta-lactam antibiotics is recommended. this could help prevent the ...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.
background extended-spectrum β-lactamase (esbl)-producing klebsiella pneumonia has become widespread in hospitals and is increasing in community settings. most of k. pneumonia that harbor these enzymes, display resistance to other unrelated antimicrobial agents and thus, often pose a therapeutic dilemma. objectives this study was conducted to determine the prevalence of esbl-producing k. pneumo...
Background and objective: Extended Spectrum Beta lactamases (ESBL) such as TEM (Temoneria) is one of the bases of antibiotic resistance in Escherichia coli isolates. The aim of this study was evaluation of TEM Extended Spectrum Beta lactamase producing E. coli, in clinical samples isolated from Zanjan hospitals, by phenotypic and PCR methods. Materials and Methods: In this cross-sectional study...
objective(s) production of extended-spectrum beta-lactamases (esbls) by enteric bacteria continues to be a major problem in hospitals and community. esbls producing bacteria cause many serious infections including urinary tract infections, peritonitis, cholangitis and intra-abdominal abscess. the aim of this study was to determine the prevalence of esbls producing escherichia coli and klebsiell...
objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...
