ABSTRACT: The indiscriminate use of antibiotics in fish farming emerges of antimicrobial resistant bacteria which is one of the most important current threats to public health. This study aimed to observe the pattern of multidrug resistant bacteria isolated from fish samples at cultured (antibiotic used) and natural ponds (no antibiotic) in Noakhali region. A total 58 Bacteria (nine bacterial genera) isolated from ten fishes (five fishes from cultured ponds and five from natural ponds) were identified presumptively by cultural, microscopic and biochemical test. After comparative analysis in both ponds samples, the predominant bacteria were Klebsiella spp., Pseudomonas spp., Escherichia coli, Vibrio spp. and Staphylococcus spp. which showed higher multidrug resistant pattern in antibiotic- used pond fish than non-antibiotic one. Therefore, safe human consumption of fish needs to consider continuous monitoring with avoidance misuse of antibiotics.
