Incidence of Antibiotic Resistant Bacteria In Fish Sold In Local Market In Dhaka City

Abstract

Present study was designed to evaluate the microbial contamination in fish (Olive Barb, Bele, Pale-Carplet, Pabo Catfish, Olive, Tangra, Gizzard, Nola, Tatkini, Corica Soborna) samples were collected from the several local market of Dhaka city, Bangladesh. Most of the fish samples were found to be contaminated with huge number of micro-biota within the range of 10⁵ to 10⁶ CFU/g. The maximum total viable bacterial (TVB) load was estimated observed in Pale Carplet (Amblypharyngodon mola) (4.8×10⁶ CFU/g) and the lowest count was found (1.5×10⁵ CFU/g) in tangra (Mystus spp.) Escherichia coli and Klebsiella spp. were present in olive barb, bele, tangra and gizzard while Salmonella spp. and Vibrio spp. were present in olive barb, bele, tangra and gizzard fish samples. Moreover, most of the isolated bacteria exhibited resistance against maximum antibiotics like trimethoprime/sulfamethoxazole (25 μg), erythromycin (15 μg), amoxicillin (30 μg), Ceftriaxon (30 μg), ciprofloxacin (5 μg), streptomycin (10 μg), Ampicillin (10 μg). Microbial contamination in the fish samples especially those were resistant to drugs may pose a serious threat to public health.
