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 ...

Prevalence, Incidence, and Risk Factors for Intestinal Colonization Due to Fluoroquinolone-Resistant ST131 Escherichia coli: a Longitudinal Study in Highly Dependent, Long-Term Care Facility Residents
(American Society for Microbiology, 2022)
Escherichia coli ST131 clade C is an important driver for fluoroquinolone resistance (FQ-R). We conducted a prospective observational study in residents from two long-term care facilities (LTCFs) in Seville, Spain, in 2018. ...

Strategies to potentiate bactericidal antimicrobial activity based on the suppression of bacterial stress response systems
(2023-05-25)
One of the major threats to human health is the emergence of antimicrobial resistance. Since the discovery of antimicrobials, new mechanisms of resistance have emerged. Various strategies are being studied to combat the ...

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 ...

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 ...

Interplay between IncF plasmids and topoisomerase mutations conferring quinolone resistance in the Escherichia coli ST131 clone: stability and resistance evolution
(Springer, 2021-11-17)
The Escherichia coli ST131 H30-Rx subclone vehicles CTX-M-15 plasmids and mutations in gyrA and parC conferring multidrug resistance successfully in the clinical setting. The aim of this study was (1) to investigate 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 ...

Clinical characteristics and outcome of bacteraemia caused by Enterobacter cloacae and Klebsiella aerogenes: more similarities than differences
(Elsevier, 2021)
Objectives The genus Enterobacter is a common cause of nosocomial infections. Historically, the most frequent Enterobacter species were those of Enterobacter cloacae complex and Enterobacter aerogenes. In 2019, E. ...
