Quinolone-resistant Escherichia coli at the interface between humans, poultry and their shared environment- a potential public health risk

One Health Outlook, 2023
Background Commensal Escherichia coli residing in the guts of humans and animals are reservoirs of multidrug resistance (MDR) genes, including quinolone resistance genes, in humans and poultry. This study aimed to characterize quinolones resistance in E.

The Impact of Mutations in Topoisomerase Genes and the Plasmid-Mediated Quinolone Resistance (PMQR) Determinants on the Resistance to Fluoroquinolones in Klebsiella pneumoniae

Archives of Clinical Infectious Diseases, 2017
Background: Klebsiella pneumoniae causes a variety of infections including community acquired pneumonia and nosocomial infections. Objectives: The aim of this study was to determine the plasmid-associated quinolone-resistance (PMQR) genes and mutations in quinolone-resistance determining region (QRDR) of topoisomerase genes in K. pneumoniae.

Molecular epidemiology of levofloxacin-resistant Klebsiella pneumoniae and the association of plasmid-mediated quinolone resistance genes with key biological phenotypes

Microbiology Spectrum
Klebsiella pneumoniae is a major opportunistic pathogen in China, yet the molecular epidemiology of quinolone resistance remains poorly characterized. This study analyzed 2,433 clinical isolates from 37 Chinese hospitals (2018–2022).

Distribution of plasmid-mediated quinolone resistance in Gram-negative bacteria from a tertiary hospital in Nigeria

Indian Journal of Pathology and Microbiology, 2016
Background: Until recently, mechanisms of resistance to quinolones in Gram-negative bacteria were believed to be only chromosome encoded. However, emergence of plasmid-mediated quinolone resistance (PMQR) has been reported worldwide.

Fluoroquinolone resistance among fecal extended spectrum βeta lactamases positive Enterobacterales isolates from children in Dar es Salaam, Tanzania

BMC Infectious Diseases, 2023
Background Fluoroquinolones have been, and continue to be, routinely used for treatment of many bacterial infections. In recent years, most parts of the world have reported an increasing trend of fluoroquinolone resistant (FQR) Gram-negative bacteria ...

Applied Research for Liquid-phase Chip Detection of Foodborne Salmonella Carrying Plasmid-mediated Quinolone Resistance Genes

Shipin gongye ke-ji, 2023
Objective: To establish a method to detect four genes: qnrS, aac(6')-Ib-cr, oqxA, oqxB, among the plasmid-mediated quinolone resistance (PMQR) genes carried by foodborne Salmonella by applying a novel liquid-phase chip technique.

The European Union Summary Report on Antimicrobial Resistance in zoonotic and indicator bacteria from humans, animals and food in 2023–2024

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This report presents the main findings of the 2023–2024 harmonised antimicrobial resistance (AMR) monitoring in Salmonella spp., Campylobacter jejuni and Campylobacter coli from humans, food‐producing animals (broilers, laying hens, fattening turkeys, fattening pigs and bovines under 1 year of age), and derived meat.

Characterization of Integrons and Quinolone Resistance in Clinical Escherichia coli Isolates in Mansoura City, Egypt

International Journal of Microbiology, 2021
Escherichia coli is a common pathogen in both humans and animals. Quinolones are used to treat infections caused by Gram-negative bacteria, but resistance genes emerged.

The Influence of Different Ciprofloxacin Residue Levels in Water on Quinolone Resistance and Bacterial Taxa in the Tilapia Gut

Aquaculture Research, Volume 2026, Issue 1, 2026.
The presence of ciprofloxacin (CIP) residues in aquatic environments may induce antibiotic resistance in tilapia and alter the diversity of their gut microbiota, highlighting the critical importance of understanding the risks associated with antibiotic contamination.

Molecular characterization of plasmid-mediated quinolone resistance (PMQR) and ESBLs-producing Klebsiella pneumonia isolated from an Iranian teaching hospital

, 2021
Abstract Background The spread of plasmid-mediated multidrug resistance in Klebsiella pneumonia is a serious threat to the public health. We investigated the clinical characteristics and molecular epidemiology of K. pneumoniae isolated at a teaching hospital in Iran.
