Warming is Associated With More Encoded Antimicrobial Resistance Genes and Transcriptions Within Five Drug Classes in Soil Bacteria: A Case Study and Synthesis

Environmental Microbiology, Volume 27, Issue 4, April 2025.
We found a positive relationship between reported optimal temperature and the number of encoded AMR genes in published soil bacterial genomes. We also observed increased AMR transcription in soil transcriptomes undergoing experimental warming and drying in a natural ecosystem. Warming effects varied by drug class. ABSTRACT The effect of warming on anti‐

Prevalence of Plasmid‐Mediated Fluoroquinolone Resistance Genes in Pseudomonas aeruginosa Among Patients at Aleppo University Hospital, Syria

Journal of Clinical Laboratory Analysis, Volume 39, Issue 4, February 2025.
Plasmid‐mediated fluoroquinolone‐resistance genes were identified in Pseudomonas aeruginosa isolated from Aleppo University Hospital along with virulence factors. ABSTRACT Background Pseudomonas aeruginosa is a significant opportunistic pathogen, especially in hospital‐acquired infections, with plasmid‐mediated fluoroquinolone resistance posing a major

Resistance Profiling of Predominant Non–E. coli Enterobacteriaceae Isolated From Humans, Food Animals, and the Environment in the Fako Division of Cameroon

BioMed Research International, Volume 2025, Issue 1, 2025.
The impact of the current global rising resistance of Enterobacteriaceae to antibiotic agents is of great concern. Detecting and monitoring resistance in these pathogens in humans, animals, and the environment and taking appropriate actions based on results obtained are indispensable to reverse this trend.
