Genomic identification, pangenome analysis, and antimicrobial resistance of Aeromonas spp. isolated from food and foodborne outbreaks.

However, a higher average nucleotide identity threshold is required to distinguish closely related species.

Some strains contained mobile elements carrying antimicrobial resistance gene clusters, such as transposon Tn5393 and antibiotic-resistant plasmids, providing mechanistic insights into their potential for horizontal antimicrobial gene transfer and adaptive evolution.
