mcr‐Mediated Colistin Resistance in Escherichia coli: A One Health Review of Reported Prevalence Across Human, Animal, Food, and Environmental Sectors

Public Health Challenges, Volume 5, Issue 3, September 2026.
This One Health review maps the global prevalence of mcr‐mediated colistin resistance in Escherichia coli across human, animal, food, and environmental sectors. By tracking datasets across diverse geographic regions, the study highlights critical resistance hotspots, emphasizing the urgent need for integrated cross‐sectoral surveillance to limit global

Chromosomal mutations that accompany qnr in clinical isolates of Escherichia coli

International Journal of Antimicrobial Agents, 2018
We examined 13 qnr-positive and 14 qnr-negative clinical isolates of Escherichia coli for mutations previously seen in a qnr-containing laboratory strain exposed to supra minimum inhibitory concentrations (MICs) of ciprofloxacin. Among the qnr-positive strains, those with ciprofloxacin MICs of ≥ 2 µg/mL had at least one mutation in gyrA.

Prevalence and Genomic Characterization of mcr‐Positive Enterobacteriaceae in Retail Meat in Thailand Following the Colistin Ban

Microbiology and Immunology, Volume 70, Issue 9, Page 402-415, September 2026.
ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

Plasmidic qnrA3 enhances Escherichia coli fitness in absence of antibiotic exposure. [PDF]

PLoS ONE, 2011
The widespread presence of plasmid-mediated quinolone resistance determinants, particularly qnr genes, has become a current issue. By protecting DNA-gyrase from quinolones, Qnr proteins confer a low level quinolone resistance that is not sufficient to ...

CCT2 Promotes Prostate Cancer Progression Through EIF3F‐Dependent Stabilization of FASN

Advanced Science, Volume 13, Issue 48, 28 August 2026.
ABSTRACT Prostate cancer (PCa) is increasingly recognized to be driven by dysregulated lipid metabolism. Although fatty acid synthase (FASN) is highly expressed in PCa, the mechanisms governing FASN protein stability and its functional integration into oncogenic lipid metabolism remain poorly defined.

Structural and Biochemical Analysis of the Pentapeptide Repeat Protein Efs Qnr, a Potent DNA Gyrase Inhibitor

, 2011
The chromosomally encoded Qnr homolog protein from Enterococcus faecalis ( Efs Qnr), when expressed, confers to its host a decreased susceptibility to quinolones and consists mainly of tandem repeats, which

Aquatic Environments as Hotspots of Transferable Low-Level Quinolone Resistance and Their Potential Contribution to High-Level Quinolone Resistance

Antibiotics, 2022
The disposal of antibiotics in the aquatic environment favors the selection of bacteria exhibiting antibiotic resistance mechanisms. Quinolones are bactericidal antimicrobials extensively used in both human and animal medicine.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Holistic analysis of sustainable waste streams used as lettuce fertilizers applied individually and in combinations

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Sustainable nutrient management is essential for agriculture in arid regions such as Yuma, Arizona, which produces over 90% of US. winter leafy greens. Nutrient‐rich waste streams, including biosolids, manure, and source‐separated urine, can reduce reliance on synthetic fertilizers but may introduce chemical and microbiological contaminants ...
