Incidence of Class 1 Integrons in a Quaternary Ammonium Compound-Polluted Environment [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2005
ABSTRACTSamples of effluent and soil were collected from a reed bed system used to remediate liquid waste from a wool finishing mill with a high use of quaternary ammonium compounds (QACs) and were compared with samples of agricultural soils. Resistance quotients of aerobic gram-negative and gram-positive bacteria to ditallowdimethylammomium chloride ...

Activation of class 1 integron integrase is promoted in the intestinal environment

open access: yesPLOS Genetics, 2022
Class 1 integrons are widespread genetic elements playing a major role in the dissemination of antibiotic resistance. They allow bacteria to capture, express and exchange antibiotic resistance genes embedded within gene cassettes. Acquisition of gene cassettes is catalysed by the class 1 integron integrase, a site-specific recombinase playing a key ...

Imported Retail Beef and Chicken Meat Products Serve as Reservoirs for Emerging Antibiotic‐Resistant Pathotypes of Escherichia coli in Pristine Areas Free From Agricultural Activity

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
Retail meat–derived E. coli frequently harbored multidrug‑resistance phenotypes, diverse virulence determinants, and plasmid‑encoded resistance genes with high conjugative potential. Results indicate meat and poultry as underrecognized reservoirs facilitating dissemination of antimicrobial resistance and pathogenic lineages, with imported products ...

Novel Class 1 Integrons in Multi-drug Resistant Isolates from Eastern China [PDF]

open access: yesIndian Journal of Microbiology, 2013
Integrons are mobile genetic elements able to capture, express and excise resistance genes, playing an important role in the spread of bacterial resistance. The present study was to investigate the occurrence and diversity of integrons in 120 clinical multi-drug resistant Gram-negative isolates from eastern China.

Antimicrobial Effect of Spices and Their Phytochemicals: A Novel Approach to Overcoming Antibiotic Resistance

open access: yesMedComm, Volume 7, Issue 4, April 2026.
This graphical abstract shows the antibacterial potential of phytochemicals from 15 spices, showcasing key compounds, their extraction methods, and mechanisms of action. It highlights membrane disruption, ROS generation, enzyme inhibition, and biofilm prevention as core antibacterial pathways.

Mechanism and Molecular Design Principles of Cationic Surfactants: From Charge‐Driven Membrane Interactions to Next‐Generation Quaternary Ammonium Compounds

open access: yesChemMedChem, Volume 21, Issue 5, 13 March 2026.
Within this review we provide an overview of the social relevance of quaternary ammonium surfactants, different classes of these agents, their interaction mechanism with cellular membranes, structure activity relation, bacterial resistance toward these systems and new approaches to guarantee their long‐term efficiency.

Removal of Antibiotic Resistance Genes in an Anaerobic Membrane Bioreactor Treating Primary Clarifier Effluent at 20 °C [PDF]

open access: yes, 2018
Anaerobic membrane bioreactors (AnMBR) play a key role in future plans for sustainable wastewater treatment and resource recovery because they have no energy-intensive oxygen transfer requirements and can produce biomethane for renewable energy.
