First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Multivariate Analysis of Factors Influencing the Concentration of Persistent Organic Pollutants and Microplastics in Mosses Sampled Across Germany in 2020

open access: yesAtmosphere
Mosses (Bryophyta) are well-established biomonitors of atmospheric deposition, including persistent organic pollutants (POPs) and microplastics (MPs). Using German Moss Survey 2020 data, this study identified factors influencing POPs and MPs in mosses ...

Aerobactin-Mediated Iron Acquisition Enhances Biofilm Formation, Oxidative Stress Resistance, and Virulence of Yersinia pseudotuberculosis

open access: yesFrontiers in Microbiology, 2021
Aerobactin is a citrate-hydroxamate siderophore that is critical for the virulence of pathogenic enteric bacteria. However, although the aerobactin-producing iucABCD-iutA operon is distributed widely in the genomes of Yersinia species, none of the ...

Emergence of Ceftazidime‐Avibactam‐Induced KPC Variants (KPC‐25/127) in Intracranial Infection and Implications for Clinical Management

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Novel KPC‐25 and first‐reported KPC‐127 sequentially evolved in one patient under CAZ‐AVI pressure, distinct mutations remodel enzyme activity to drive differential multidrug resistance. ABSTRACT The emergence of novel Klebsiella pneumoniae carbapenemase (KPC) variants contributing to clinical treatment failure poses a substantial threat to public ...
