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 ...

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
(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 ...

Population pharmacokinetics and pharmacodynamics of fosfomycin in non-critically ill patients with bacteremic urinary infection caused by multidrug-resistant Escherichia coli
(Elsevier, 2018)
Objectives: To describe the population pharmacokinetics of fosfomycin for patients with bacteraemic urinary tract infection (BUTI). The analysis identified optimal regimens on the basis of pharmacodynamic targets and ...

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 ...

Effectiveness of fosfomycin trometamol as oral step-down therapy for bacteraemic urinary tract infections due to MDR Escherichia coli: a post hoc analysis of the FOREST randomized trial
(Oxford Academic, 2023)
Background Fosfomycin is a potentially attractive option as step-down therapy for bacteraemic urinary tract infections (BUTI), but available data are scarce. Our objective was to compare the effectiveness and safety of ...

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 ...
