Interplay Among Different Fosfomycin Resistance Mechanisms in Klebsiella Pneumoniae
(American Society for Microbiology, 2021)
The objectives of this study were to characterize the role of the uhpT, glpT, and fosA genes in fosfomycin resistance in Klebsiella pneumoniae and evaluate the use of sodium phosphonoformate (PPF) in combination with ...

Cellular Response to Ciprofloxacin in Low-Level Quinolone-Resistant Escherichia coli
(Frontiers Media, 2017)
Bactericidal activity of quinolones has been related to a combination of DNA fragmentation, reactive oxygen species (ROS) production and programmed cell death (PCD) systems. The underlying molecular systems responsible ...

Evaluation of temocillin efficacy against KPC-2-producing Klebsiella pneumoniae isolates in a hollow-fibre infection model
(Oxford University Press, 2024-02-09)
Background: Temocillin is an old antimicrobial that is resistant to hydrolysis by ESBLs but has variable activity against carbapenemase-producing Enterobacteriaceae. The current EUCAST susceptibility breakpoints ...

Detection of plasmid-mediated quinolone resistance genes in clinical isolates of Enterobacter spp. in Spain
(American Society for Microbiology, 2009)
We have studied by PCR and DNA sequencing the presence of the qnrA, qnrB, qnrS, aac(6′)-Ib-cr, qepA, intI1, and ISCR1 genes in 200 clinical isolates of Enterobacter cloacae (n = 153) and E. aerogenes (n = 47) consecutively ...

Pharmacodynamics of fosfomycin: Insights into clinical use for antimicrobial resistance
(American Society for Microbiology, 2015-09-01)
The aim of this study was to improve the understanding of the pharmacokinetic-pharmacodynamic relationships of fosfomycin against extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains that have different ...

Efficacy of cefepime and imipenem in experimental murine pneumonia caused by porin-deficient Klebsiella pneumoniae producing CMY-2 β-lactamase
(American Society for Microbiology, 2005-08-01)
Previous studies have shown decreased in vitro activity of zwitterionic cephalosporins and carbapenems against porin-deficient Klebsiella pneumoniae expressing a plasmid-mediated AmpC-type β-lactamase (PACBL). The in vitro ...
