Emergence of colistin resistance and characterization of antimicrobial resistance and virulence factors of <i>Aeromonas hydrophila</i> , <i>Salmonella</i> spp., and <i>Vibrio cholerae</i> isolated from hybrid red tilapia cage culture

Abstract

Findings from this study on AMR bacteria in hybrid red tilapia suggest that aquaculture as practiced in Thailand can select for ubiquitous AMR pathogens, mobile genetic elements, and an emerging reservoir of <i>mcr</i> and colistin-resistant bacteria. Resistant and pathogenic bacteria, such as resistance to ampicillin and tetracycline, or MDR <i>Salmonella</i> circulating in aquaculture, together highlight the public health concerns and foodborne risks of zoonotic pathogens in humans from cultured freshwater fish.
