Effect of Glycerol on Fosfomycin Activity against Escherichia coli
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Fosfomycin is an antimicrobial that inhibits the biosynthesis of peptidoglycan by entering the bacteria through two channels (UhpT and GlpT). Glycerol is clinically used as a treatment for elevated intracranial pressure ...

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 ...

Detection of low-level fosfomycin-resistant variants by decreasing glucose-6-phosphate concentration in fosfomycin susceptibility determination
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Mutations that confer low-level fosfomycin resistance (LLFR) but not clinical resistance in Escherichia coli are increasingly reported. LLFR strains can become clinically resistant under urinary tract physiological conditions ...

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 ...

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 ...

Quinolone Resistance Reversion by Targeting the SOS Response
(American Society for Microbiology, 2017)
Suppression of the SOS response has been postulated as a therapeutic strategy for potentiating antimicrobial agents. We aimed to evaluate the impact of its suppression on reversing resistance using a model of isogenic ...

Optimisation of the therapeutic potential of fosfomycin against Enterobacteriaceae: characterisation of genetic and physiological factors related to resistance and antimicrobial activity
(2023-05-30)
Since the discovery of the first antimicrobials, bacteria with resistance mechanisms against them have been detected. The appearance of bacterial resistance is a natural phenomenon, which has increased as a result of the ...

Disbalancing Envelope Stress Responses as a Strategy for Sensitization of Escherichia coli to Antimicrobial Agents
(Frontiers Media, 2021)
Disbalancing envelope stress responses was investigated as a strategy for sensitization of Escherichia coli to antimicrobial agents. Seventeen isogenic strains were selected from the KEIO collection with deletions in genes ...

Synergistic Quinolone Sensitization by Targeting the recA SOS Response Gene and Oxidative Stress
(American Society for Microbiology, 2021-03-18)
Suppression of the recA SOS response gene and reactive oxygen species (ROS) overproduction have been shown, separately, to enhance fluoroquinolone activity and lethality. Their putative synergistic impact as a strategy to ...
