The R plasmid pRAS2 in the fish pathogen Aeromonas salmonicida is a global mediator of antibiotic resistance in aquaculture and can be used by pRAS3 for mobilization
Horizontal gene transfer (HGT) mediated by conjugative plasmids is a major driver of antimicrobial resistance (AMR) dissemination in aquatic environments. In Aeromonas salmonicida , plasmid-mediated HGT is largely driven by the pRAS plasmid family. Here we present genomic and experimental characterization of pRAS2...
