Fecal 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 کاملFecal carriage of extended-spectrum β-lactamase- and AmpC- producing Escherichia coli among healthcare workers.
INTRODUCTION Commensal E. coli can be considered a reservoir of genes coding for antibiotic resistance that may be transmitted in hospitals by healthcare workers (HCWs). This study aimed to determine the fecal carriage rate of extended-spectrum β-lactamase (ESBL)-producing E. coli among HCWs. METHODOLOGY Stool samples were collected from 200 HCWs. Phenotypic screening for ESBL and AmpC β-lact...
متن کاملFecal carriage of Escherichia coli harboring extended-spectrum beta-lactamase (ESBL) genes by sheep and broilers in Urmia region, Iran
Background: There is a growing concern on the impact of the presence of extended-spectrum β-lactamase (ESBL) producing Escherichia coli isolated from animals on public health. OBJECTIVES: The aim of this study was to investigate the presence of three classes of ESBL genes in E. coli isolates from sheep and broilers at a slaughter in Urmia region, Iran. METHODS: A total of 111 E. coli isolates w...
متن کاملExtended-Spectrum- -Lactamase, AmpC, and Carbapenemase Issues
Optimal use of microbiology laboratories is essential to combat the spread of multiply antibiotic-resistant pathogens. This is vital for patient care, as advocated by Jarvis in stressing the importance of active detection and isolation to control methicillin-resistant Staphylococcus aureus and other resistant hospital-acquired pathogens (17). It is also vital for hospital accreditation in the U...
متن کاملEmergence 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...
