    The alarming rise of multi-drug resistant (MDR)bacteria pathogenic to humans and animals poses amajor threat to the public health sector. Enterococciare a complex group of bacteria that causesnosocomial infections in humans. It has been widelyacknowledged that the environmental loading ofantibiotics from hospitals, livestock farms, aquacul-ture sector and sewage plants create a hot spot forthe emergence of antimicrobial resistance (AMR).The sediment, water and fish samples from Pangasiusculture ponds using raw and cooked poultry wasteas feed, and normal fish feed were screened for thepresence of MDR Enterococcus faecalis. AMR wasanalysed by Kirby-Bauer disc diffusion method.Among the 83 enterococci isolates, 65 % of theisolates were E. faecalis, all of which exhibited multi-drug resistant phenotypes. The isolates showedmaximum resistance to macrolide, tetracycline andlincosamide (100 %) class of antimicrobials. Thepresent study reflects the impact of erroneouspractices followed by certain farmers in spreadingAMR in aquaculture and environment and theoccurrence of MDR enterococci in aquaculturefarms is a matter of serious concern. Awarenessprogrammes among farmers, better regulations,regular surveillance and encouraging adoption ofbetter management practices can go a long way tolimit the spread of such MDR superbugs.
