abstract background: pseudomonas aeruginosa is one of the most common gram negative bacteria involved in nosocomial infections. presence of extended-spectrum beta-lactamases (esbls) genes, play an important role in induction of resistance in beta-lactamase producing species to beta lactam antibiotics. frequency of resistance to these antibiotics is increasing. in this study, antibiotic sensitiv...
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...
conclusions this study was the first report of the emergence of the plasmid-encoded blaoxa genes among e. cloacae isolates in iran. these findings highlight the need to use appropriate infection control policy and rational antibiotic therapy to reduce further spread of these resistant bacteria in the studied hospitals. results in total, 48 esbl-producing isolates (58.5%) were positive for the b...
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...
Background and Aim: Klebsiella pneumoniae (K. Pneumoniae) is one of the prevalent infectious bacteria, especially in hospitalized patients. Recently, its' multi drug resistance (MDR) trait has become more important and regarded as a virulant factor. In this study, we evaluated bla-ctx-m-type gene in clinical isolates of K.pneumoniae with multi drug resistance. Materials and Methods: In this d...
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In...
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...
Production of extended-spectrum beta-lactamases and plasmid-mediated AmpC enzymes was investigated among 291 Escherichia coli and 282 Klebsiella pneumoniae isolates that showed decreased susceptibilities to extended-spectrum cephalosporins from seven Taiwanese medical centers. CTX-M-type and SHV-type enzymes were the most prevalent extended-spectrum beta-lactamases. CMY-2-like and DHA-1-like be...
Background and aim: Antimicrobial resistance is a worldwide problem causing health threats. Escherichia coli is one of the most important bacteria that causes resistance problems. The aim of this study was to evaluate the frequency of Escherichia coli, a extended spectrum beta-lactamase producing CTX-M and SHV, in hospital and non-hospital clinical specimens in Isfahan. Methods: In this stu...
