High heterogeneity of plasmid-mediated quinolone resistance in Escherichia coli isolates recovered from livestock and food in Germany

open access: yes, 2020
Introduction: Resistance to quinolones can be chromosomally encoded or plasmid-mediated (PMQR). One PMQR mechanism is mediated by Qnr proteins. The horizontal gene transfer of this plasmid-mediated quinolone resistance increases the threat of fallible ...

Presence of qnr gene in Escherichia coli and Klebsiella pneumoniae resistant to ciprofloxacin isolated from pediatric patients in China

open access: yesBMC Infectious Diseases, 2008
Background Quinolone resistance in Enterobacteriaceae results mainly from mutations in type II DNA topoisomerase genes and/or changes in the expression of outer membrane and efflux pumps.

Antibiotics in Veterinary Ophthalmology: Resistance, Stewardship, and Emerging Antibiotic‐Sparing Strategies

open access: yesVeterinary Ophthalmology, Volume 29, Issue 4, July 2026.
ABSTRACT Antimicrobial resistance (AMR) is a growing challenge in veterinary ophthalmology, particularly in cases of bacterial keratitis, where progressive stromal infection can threaten vision and globe integrity within hours to days. This review synthesizes current evidence on pathogen distribution, antimicrobial susceptibility profiles, multidrug ...

Guidelines for Detecting the Foodborne Antibiotic‐Resistant Bacteria

open access: yesAgriFood: Journal of Agricultural Products for Food, Volume 2, Issue 2, Page 152-164, June 2026.
ABSTRACT Foodborne antibiotic‐resistant bacteria threaten global public health and the economic. Standardized detection methods are crucial for effective prevention and control. Researchers encounter difficulties in choosing suitable techniques due to the variety of available approaches and the intricate nature of resistance mechanisms.

Plasmid-mediated quinolones resistance in clinically important bacteria [PDF]

open access: yesThe Journal of Qazvin University of Medical Sciences, 2018
Quinolones are synthetic and commonly used antibiotics for treatment of multiple clinical infections in the world. Quinolones are clinically important antibiotics, as an ideal component, because of high potency, broad-spectrum activity, good bioavailability and a potentially low incidence of side-effects.

Genomic epidemiology and lineage‐specific risk stratification of tet(X4)‐mediated tigecycline resistance along the pork production chain: A One Health perspective

open access: yesiMetaOmics, Volume 3, Issue 2, June 2026.
Genome surveillance across a swine‐associated One Health continuum in China shows that slaughterhouses act as major enrichment nodes for tet(X4)‐mediated tigecycline resistance, driven by putative clonal transmission and stable plasmid backbones. Integrating global datasets enables lineage‐specific risk stratification, highlighting key control points ...
