Prevalence and transmission dynamics of Escherichia coli ST131 among contacts of infected community and hospitalized patients
(Elsevier, 2018)
Objectives: The Escherichia coli O25b-associated ST131 clonal group was recently found to be prevalent in our area as a cause of community-acquired urinary tract infections. We evaluated the transmission dynamics and ...

Development of resistance during antimicrobial therapy caused by insertion sequence interruption of porin genes
(American Society for Microbiology, 1999-01-01)
We have demonstrated by using an in vitro approach that interruption of the OmpK36 porin gene by insertion sequences (ISs) is a common type of mutation that causes loss of porin expression and increased resistance to ...

Excretion and viability of SARS‑CoV‑2 in feces and its association with the clinical outcome of COVID‑19
(Nature Publishing Group, 2022)
The main objective was to evaluate the viability of the SARS-CoV-2 viral particles excreted in stools. In addition, we aimed to identify clinical factors associated with the detection of SARS-CoV-2 RNA in feces, and ...

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 ...

Uptake and intracellular activity of trovafloxacin in human phagocytes and tissue-cultured epithelial cells
(American Society for Microbiology, 1997-02-01)
The penetration of trovafloxacin into human polymorphonuclear leukocytes (PMNs), human peritoneal macrophages, and tissue-cultured epithelial cells (McCoy cells) was evaluated. The cellular concentration to extracellular ...

Characterization of the carbapenem-hydrolyzing oxacillinase oxa-58 in an Acinetobacter genospecies 3 clinical isolate
(American Society for Microbiology, 2008-08-01)
Based on imipenem resistance in an Acinetobacter genospecies 3 clinical isolate, we were able to identify, for the first time in this genomic species, a plasmid-encoded blaOXA-58 gene that was 100% homologous to the same ...

In vitro activity of cefiderocol and comparators against isolates of Gram-negative bacterial pathogens from a range of infection sources: SIDERO‑WT‑2014−2018 studies in Spain
(Science Direct, 2021-07-15)
Objectives: The incidence of antimicrobial resistance in Europe is rising. Cefiderocol is approved in Eu- rope for treatment of aerobic Gram-negative bacterial (GNB) infections in adults with limited treatment options. ...

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 ...
