Emergence of ertapenem resistance in an Escherichia coli clinical isolate producing extended-spectrum beta-lactamase AmpC.
Escherichia coli isolate MEV, responsible for a bloodstream infection, was resistant to penicillins, cephalosporins, and ertapenem. Molecular and biochemical characterization revealed the production of a novel, chromosome-borne, extended-spectrum AmpC (ESAC) β-lactamase with a Ser-282 duplication and increased carbapenemase activity. This study demonstrates for the first time that chromosome-bo...
متن کاملLytic Activity of Isolated Phage from Milk Against Extended-Spectrum Beta-Lactamase Escherichia coli
Background and purpose: Escherichia coli (E.coli) is the most common cause of urinary tract infection. The treatment strategy has been hampered by the emergence of broad-spectrum beta-lactamase-producing E.coli and its resistance to most antibiotics. Bacteriophages are suggested as an alternative treatment option. This study aimed at evaluating the lytic activity of isolated phage from unpaste...
متن کاملFecal Colonization with Extended-Spectrum Beta-Lactamase and AmpC-Producing Escherichia coli
Background. Extended-spectrum β-lactamases (ESβLs) and AmpC β-lactamases cause β-lactam resistance in Escherichia coli. Fecal colonization by ESβL- and/or AmpC-positive E. coli is a source of nosocomial infections. Methods. In order to investigate inpatient fecal colonization by ESβLs and AmpC, antibiotic sensitivity tests were conducted and minimum inhibitory concentrations (MICs) were determi...
متن کاملExposure assessment of extended-spectrum beta-lactamases/AmpC beta-lactamases-producing Escherichia coli in meat in Denmark
INTRODUCTION Extended-spectrum beta-lactamases (ESBL) and AmpC beta-lactamases (AmpC) are of concern for veterinary and public health because of their ability to cause treatment failure due to antimicrobial resistance in Enterobacteriaceae. The main objective was to assess the relative contribution (RC) of different types of meat to the exposure of consumers to ESBL/AmpC and their potential imp...
متن کاملEmergence of Escherichia coli producing extended-spectrum AmpC β-lactamases (ESAC) in animals
In both humans and animals, the spread of Extended-Spectrum β-Lactamases (ESBL)/AmpC producers has become a major issue, particularly due to the plasmidic dissemination of most of these genes. Besides, over-expression of the chromosomal ampC gene was largely reported in human and animal Enterobacteriaceae and, more recently, modifications within the coding region of the ampC gene [encoding Exte...
