Prevalence of qnrS-positive Escherichia coli from chicken in Thailand and possible co-selection of isolates with plasmids carrying qnrS and trimethoprim-resistance genes under farm use of trimethoprim

Poultry Science, 2022
One hundred and twenty chicken samples from feces (n = 80), the carcass surface at slaughter at 2 meat chicken farms (n = 20), and retail chicken meat from 5 markets (n = 20) collected during 2018 and 2019 were examined for the prevalence of plasmid-mediated quinolone resistance (PMQR) in Escherichia coli. We detected qnrS-positive E.

Mechanisms of quinolone resistance and implications for human and animal health [PDF]

Veterinarski Glasnik, 2010
Quinolone antibiotics have been widely used in human and veterinary medicine. This has caused the development of resistance and difficulties in the treatment of complicated bacterial infections in humans.

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.

Quantum Activation Functions in Neural Networks: A Systematic Review of Approaches, Performance Impacts, and Practical Applications

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
This review explores how quantum activation functions can contribute to the evolution of neural networks toward quantum computing. The results show that classical‐quantum hybrid architectures are being tested in some practical applications, while fully quantum models are still in the development phase. These functions represent an important step toward

Phenotypic and Genotypic Evaluation of Resistance to Fluoroquinolones in Klebsiella pneumoniae Collected from Hospitalized Patients in Sari, Iran

Journal of Mazandaran University of Medical Sciences, 2021
Background and purpose: Antibiotic resistance of Klebsiella pneumoniae to quinolones is a serious concern in treatment of nosocomial infections. There are limited reports on the prevalence of plasmid-mediated quinolone resistance genes in K.

Predictive analysis of transmissible quinolone resistance indicates Stenotrophomonas maltophilia as a potential source of a novel family of Qnr determinants

BMC Microbiology, 2008
Background Predicting antibiotic resistance before it emerges at clinical settings constitutes a novel approach for preventing and fighting resistance of bacterial pathogens.

Pathogenicity and Antimicrobial‐Resistance Profiles of Escherichia coli Isolated From Faeces of Tibetan Pigs Reared Under Intensive Conditions

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Tibetan pig farms host diverse Escherichia coli strains that resist multiple antibiotics and carry important disease genes, such as astA. These traits jump easily between bacterial groups, marking intensive pig production as a key reservoir and signalling the need for integrated animal–human surveillance and more careful antibiotic use.

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.
