Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

open access: yesAnimal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

A Phylogenomic Backbone for Gastropod Molluscs

open access: yesSystematic Biology, 2022
AbstractGastropods have survived several mass extinctions during their evolutionary history resulting in extraordinary diversity in morphology, ecology, and developmental modes, which complicate the reconstruction of a robust phylogeny. Currently, gastropods are divided into six subclasses: Caenogastropoda, Heterobranchia, Neomphaliones, Neritimorpha ...

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

open access: yesAnimal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.
