Association of opportunistic human bacterial pathogens in cultured freshwater fishes of Kolkata,
India and their sensitivity to broad spectrum antibiotics was investigated. Both indigenous and non-indigenous
human bacterial pathogens such as Aeromonas hydrophila, A. caviae, Edwardsiella tarda, Escherichia coli,
Pseudomonas spp. and Vibrio parahaemolyticus were isolated from freshwater fishes of Kolkata. These strains
were highly resistant to oxytetracycline (62%) and nitrofurantoin (46%), and sensitive to ciprofloxacin (91%)
and chloramphenicol (89%). Multiple Antibiotic Resistance (MAR) was high in catfishes (76%) followed by
miscellaneous fishes (66%) and sewage-fed farm grown carps (55%). Among the bacterial species, the MAR
was high in Ed. tarda (86%). More than 50% of the strains of A. hydrophila, A. caviae, E. coli, Pseudomonas
spp., V. parahaemolyticus and unidentified Gram positive rods exhibited MAR. The results suggested that there
is added risk of antibacterial resistance developing in the emerging human bacterial pathogens from freshwater
aquaculture and of such antibiotic resistant bacterial pathogens entering the food chain.
Key words: Antibiotic resistance, food safety hazards, fish-borne pathogens, freshwater aquaculture, , ,
