Background: Klebsiella pneumoniae is one of the most important and prevalent bacterium isolated from clinical cases especially from hospitalized patients. Recent studies have focused on multiple drug resistant K.pneumoniae strains. In this survey, drug resistance in clinical isolates was studied with special reference to extended spectrum β-lactamase. Methods: A total of 303 K.pneumoniae strai...
background extended-spectrum beta-lactamases (esbls) are a group of enzymes that hydrolyze antibiotics, including those containing new cephalosporins, and they are found in a significant percentage of escherichia coli and klebsiella pneumoniae strains. with the widespread use of antibiotics, difficulties with infection therapy caused by drug resistant organisms, especially those that have acqui...
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...
The occurrence of extended-spectrum beta-lactamases-producing bacteria is an important public health issue. The aim of this study was to investigate phenotypic and genotypic characteristics regarding the presence of extended spectrum β-lactamase ctx-m, per and ver producing Escherichia coli isolated from raw dairy samples. For this purpose, E. coli were isolated from 247 raw dairy samples (milk...
Background & Aim: clinical cases especially from hospitalized patients. Recently multiple drug resistant isolated from clinical cases. Resistances were seen against drugs belonging to different antibiotic families. In thissurvey, drug resistance in clinical isolates was studied with special reference to extended spectrum betalactamases.Escherichia coli is one of the most important and prevalent...
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: there are few therapeutic options for treatment of multidrug resistant klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). the aim of this study was to evaluate the antibacterial activity of zataria multiflora boiss extracts against esbl-producing klebsiella pneumoniae strains. materials and methods: this study was conducted on 100 k. pneumoniae isola...
