Emergence of Plasmid-Mediated Quinolone Resistance in Escherichia coli in Europe [PDF]

Antimicrobial Agents and Chemotherapy, 2005
ABSTRACT Although quinolone resistance results mostly from chromosomal mutations, it may also be mediated by a plasmid-encoded qnr gene in members of the family Enterobacteriaceae . Thus, 297 nalidixic-acid resistant strains of 2,700 Escherichia coli strains ...

Prevalence, Antimicrobial Resistance, and Resistance Gene Profiles of Extended‐Spectrum β‐Lactamase‐Producing Escherichia coli and Klebsiella pneumoniae Isolated From Quails in Sylhet, Bangladesh

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
This study investigated the molecular epidemiology and antimicrobial resistance of Escherichia coli and Klebsiella pneumoniae isolated from quails in Bangladesh. High prevalence of E. coli, including Shiga toxin‐producing strains, and widespread multidrug resistance were observed.

Occurrence and characterization of quinolone resistant Escherichia coli from Norwegian turkey meat and complete sequence of an IncX1 plasmid encoding qnrS1.

PLoS ONE, 2019
Plasmid-mediated quinolone resistance (PMQR) is frequent among Escherichia coli from various food products and animals in several countries. The objective of this study was to characterize quinolone resistant E.

The Role of Neonatal Ward Environment as a Reservoir for the Dissemination of Multidrug‐Resistant Klebsiella pneumoniae in Algeria

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Whole‐genome sequencing of multidrug‐resistant Klebsiella pneumoniae from a neonatal ward environment in Chlef revealed persistent resistance genes and the clonal spread of high‐risk ST13. These findings highlight the hospital environment as a potential reservoir for transmission of resistant K. pneumoniae.

The Role of N6‐Methyladenosine Modification in Health and Disease

MedComm, Volume 7, Issue 6, June 2026.
N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.

Chlorpromazine inhibits the plasmid-mediated oqxAB multidrug efflux pump in Escherichia coli isolates of Egyptian patients with utis

BMC Microbiology
Over the past ten years, the prevalence of the OqxAB efflux pump, a plasmid-mediated quinolone resistance determinant, has increased among Escherichia coli (E. coli) isolates.

Genomic Insights Into Carbapenem‐Resistant Klebsiella pneumoniae in Pediatric Bloodstream Infections in Zhejiang, China (2019–2024)

Journal of Clinical Laboratory Analysis, Volume 40, Issue 10, May 2026.
The primary mechanism of carbapenem resistance identified in pediatric CRKP‐BSI strains was the production of Class B metalloenzymes. We report, for the first time, an outbreak of bloodstream infections in a neonatal ward caused by the dissemination of NDM‐1‐producing ST25 K. pneumoniae.
