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.

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.

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
