GNPS Untargeted GC‐MS Metabolomic Analysis of Essential Oils From Duguetia lanceolata and Evaluation of Antimicrobial Activity

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.

Structured Promoter Variability in Epigenetically Regulated Operons Contributes to Surface Adaptation in Salmonella

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
We discovered that Salmonella uses structured, recurrent variation in epigenetically regulated promoter regions to fine‐tune gene expression, revealing a novel evolutionary strategy for surface adaptation. ABSTRACT Bacterial adaptation to dynamic and hostile environments often relies on the ability to modify surface structures, which are subjected to ...

Genomic Analysis and Virulence Features of Vibrio cholerae Non‐O1/Non‐O139 Harbouring CARB‐Type β‐Lactamases From Freshwater Bodies, Argentina

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Genomic analysis of ampicillin‐resistant Vibrio cholerae non‐O1/non‐O139 from central Argentina's freshwater bodies identified four novel CARB‐β‐lactamase variants linked to the V. cholerae superintegron. An unusual VPI‐1 arrangement encoding the TCP pilus and a type VI secretion system subclass i5 was also found, associated with increased ...
