Background: Resistance to beta-lactam antibiotics in clinical isolates frequently results from the production of β-lactamase enzymes. In recent years, the production of extended spectrum β-lactamases (ESBLs) and AmpC β-lactamase have greatly increased, especially in clinically isolated Escherichia coli. On the other hand, beta lactamase genes have several subfamilies ...

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...

OBJECTIVES Determining the prevalence of children in day-care centres (DCCs) carrying faecal extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae and molecularly characterizing those belonging to the Escherichia coli species. METHODS Stools were collected from children's diapers (January-April 2012) in randomly chosen DCCs and plated onto ChromID ESBL. Colonies growing on this me...

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...

Background: Escherichia coli are ubiquitous bacteria colonising both humans and animals. Extended spectrum β-lactamase-producing E. has been selected as a suitable indicator for the monitoring surveillance of antimicrobial resistance. Death due to resistant is continuously rising in Cameroon, but contribution aviary sector not well studied. Therefore, this study aimed investigate resistance pro...

To review the epidemiology of nosocomial extended spectrum β-lactamase-producing Enterobacteriaceae in Latin America, a systematic search of the biomedical literature (PubMed) was performed for articles published since 2005. Rates of nosocomial infections caused by extended spectrum β-lactamase-producing Enterobacteriaceae in Latin America have increased since 2005. Up to 32% of Escherichia col...

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...

Escherichia coli is a common cause of infections in companion animals. In recent years the increasing prevalence of resistance to β-lactams, including extended-spectrum cephalosporins, antimicrobials frequently used in small animal veterinary practice, was observed in canine isolates of E. coli. The aim of this study was to detect and to characterize extended-spectrum β-lactamases (ESBLs) produ...
