Efficacy of Colistin and Its Combination With Rifampin in Vitro and in Experimental Models of Infection Caused by Carbapenemase-Producing Clinical Isolates of Klebsiella pneumoniae.
(Frontiers Media, 2018)
Despite the relevance of carbapenemase-producing Klebsiella pneumoniae (CP-Kp) infections there are a scarce number of studies to evaluate in vivo the efficacy of combinations therapies. The bactericidal activity of colistin, ...

A multinational, preregistered cohort study of β-lactam/β-lactamase inhibitor combinations for treatment of bloodstream infections due to extended-spectrum-β-lactamase-producing enterobacteriaceae
(American Society for Microbiology, 2016-07-01)
The spread of extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) is leading to increased carbapenem consumption. Alternatives to carbapenems need to be investigated. We investigated whether ...

Virulence Profiles of Bacteremic Extended-Spectrum β-Lactamase-Producing Escherichia coli: Association with Epidemiological and Clinical Features
(Public Library of Science, 2012)
There is scarce data about the importance of phylogroups and virulence factors (VF) in bloodstream infections (BSI) caused by extended-spectrum β-lactamase-producing Escherichia coli (ESBLEC). A prospective multicenter ...

Genomewide overexpression screen for fosfomycin resistance in Escherichia coli: Mura confers clinical resistance at low fitness cost
(American Society for Microbiology, 2012-05-01)
To determine whether the overexpression of chromosomal genes can confer fosfomycin resistance, genomewide screening of a complete set of 5,272 plasmid-expressed open reading frames of Escherichia coli (ASKA collection) was ...
