Prevalence and distribution of antimicrobial resistance profile of Escherichia coli isolated from various local fish markets in Dhaka city, Bangladesh

Abstract

Considering the importance of the fish and fish products as a vital part of the human diet in Bangladesh, the study aimed to estimate the microbial load, identify the E. coli and observe the isolates antibiogram pattern. Standard plate count technique, as well as the 3-tube most probable number (MPN) method, were applied to estimate the total viable bacteria (TVB) and total coliforms (TC), total fecal coliforms (TFC), and E. coli, respectively. Approximately 61.91% of samples fell into the marginally acceptable limit for TVB count, while 66.67% and 95.25% of examined species exceeded the threshold limit for TC and TFC, respectively (p<0.05). Around 90% of samples were contaminated with E. coli. A culture sensitivity test revealed that cent percent strains harbored resistance to penicillin, rifampicin, and erythromycin. Multiple antibiotic resistance (MAR) index above 0.2 may indicate the misuse or overuse of antibiotics. The findings highlight the potential food safety hazards associated with fish concerning the random use of antibiotics. J. Bangladesh Acad. Sci. 46(1); 9-18: June 2022

Knowledge, Attitude, and Practices on Antimicrobial Use and Antimicrobial Resistance among Commercial Poultry Farmers in Bangladesh

“…Using antimicrobials in poultry production systems increases the chance of antimicrobial resistance (AMR). Antimicrobials are essential to protect animal health in livestock production systems, but their misuse creates a favorable niche for AMR bacteria in livestock farms, wildlife, and the environment, which might transmit to humans through contaminated foods or direct contact [4][5][6][7][8][9][10]. Humans consuming livestock and aquaculture-derived food products might develop resistance against specific antimicrobials due to antimicrobial residues being introduced into the human food chain [11][12][13][14][15][16][17].…”
