Universidad de Zaragoza (orcid)0000-0002-2519-701X Prevalence of fecal carriage of ESBL-producing Enterobacteriaceae in hospitalized and ambulatory patients during two non-outbreak periods 2007 Beta-lactam resistance in Enterobacteriaceae associated with plasmid-mediated extended-spectrum beta-lactamase (ESBL) has become a worldwide problem. ESBLs were initially associated with nosocomial outbreaks caused by strains producing single enzymes, but recent studies have revealed a more complex situation, with a significant increase among community isolates. The rate of fecal carriage of ESBL-producing bacterial isolates in nosocomial outbreaks has been studied previously, but few prospective studies investigating the prevalence of fecal carriage during non-outbreak periods have been conducted. In an effort to fill this knowledge gap, we performed a study of hospitalized patients and outpatients to determine the prevalence of fecal carriage of ESBL-producing Enterobacteriaceae in stool samples submitted to our laboratory for culture during two non-outbreak periods separated by 17 months (April 2002–February 2003 and August 2004–July 2005)... info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.309 2007 MICROBIOLOGY 46 / 92 = 0.5 2007 Q2 T2 INFECTIOUS DISEASES 27 / 49 = 0.551 2007 Q3 T2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Seral Garcia, C.
