| Summary: | Antibiotics are widely used in intensive fish farming, which in turn increases the emergence of antimicrobial-resistant (AMR) bacteria in the aquatic environment. The current study investigates the prevalence and determines the antimicrobial susceptibility of <i>E. coli</i>, <i>Salmonella</i>, and <i>Vibrio</i> in farmed fishes on the west coast of Peninsular Malaysia. Over a period of 12 months, 32 aquaculture farms from the Malaysian states of Selangor, Negeri Sembilan, Melaka, and Perak were sampled. Both <i>E. coli</i> and <i>Salmonella</i> were highly resistant to erythromycin, ampicillin, tetracycline, and trimethoprim, while <i>Vibrio</i> was highly resistant to ampicillin and streptomycin. Resistance to the antibiotics listed as the highest priority and critically important for human therapy, such as colistin in <i>E. coli</i> (18.1%) and <i>Salmonella</i> (20%) in fish, is a growing public health concern. The multi-drug resistance (MDR) levels of <i>E. coli</i> and <i>Salmonella</i> in tilapia were 46.5% and 77.8%, respectively. Meanwhile, the MDR levels of <i>E. coli</i>, <i>Salmonella</i>, <i>V. parahaemolyticus</i>, <i>V. vulnificus</i> and <i>V. cholerae</i> in Asian seabass were 34%, 100%, 21.6%, 8.3% and 16.7%, respectively. Our findings provide much-needed information on AMR in aquaculture settings that can be used to tailor better strategies for the use of antibiotics in aquaculture production at the local and regional levels. |
