Diversity of Escherichia coli Strains Producing Extended-Spectrum B-Lactamases in Spain: Second Nationwide Study [Article]
(American Society for Microbiology, 2010-08)
The prevalence of extended-spectrum -lactamase (ESBL)-producing Escherichia coli (ESBLEC) in Spain increased 8-fold from 2000 to 2006. ESBL type, clonal relationship, antimicrobial susceptibility, and clinical data about ...
Intestinal colonization due to Escherichia coli ST131: Risk factors and prevalence [Article]
(Biomed Central, 2018-11-15)
Background Escherichia coli sequence type 131 (ST131) is a successful clonal group that has dramatically spread during the last decades and is considered an important driver for the rapid increase of quinolone resistance ...
Four main virotypes among extended-spectrum-β-lactamase-producing isolates of Escherichia coli O25b:H4-B2-ST131: bacterial, epidemiological, and clinical characteristics [Article]
(American Society for Microbiology, 2013-10)
A total of 1,021 extended-spectrum- -lactamase-producing Escherichia coli (ESBLEC) isolates obtained in 2006 during a Spanish national survey conducted in 44 hospitals were analyzed for the presence of the O25b:H4-B2-ST131 ...
Inoculum Effect on the Efficacies of Amoxicillin-Clavulanate, Piperacillin-Tazobactam, and Imipenem against Extended-Spectrum -Lactamase (ESBL)-Producing and Non-ESBL-Producing Escherichia coli in an Experimental Murine Sepsis Model [Article]
(American Society for Microbiology, 2013-04)
Escherichia coli is commonly involved in infections with a heavy bacterial burden. Piperacillin-tazobactam and carbapenems are among the recommended empirical treatments for health care-associated complicated intra-abdominal ...
Epidemiological and Clinical Complexity of Amoxicillin-Clavulanate- Resistant Escherichia coli [Article]
(American Society for Microbiology, 2013-07)
Two hundred twelve patients with colonization/infection due to amoxicillin-clavulanate (AMC)-resistant Escherichia coli were studied. OXA-1- and inhibitor-resistant TEM (IRT)-producing strains were associated with urinary ...
Virulence profiles of bacteremic extended-spectrum ß-lactamase-producing Escherichia coli: association with epidemiological and clinical features [Article]
(Public Library of Science (PLoS), 2012)
There is scarce data about the importance of phylogroups and virulence factors (VF) in bloodstream infections (BSI) caused by extended-spectrum b-lactamase-producing Escherichia coli (ESBLEC). A prospective multicenter ...
