A comparative study on the antimicrobial resistance of Escherichia coli isolates from chickens and fish grown on integrated and traditional fish farms

Escherichia coli was isolated from fish grown in a pond that had never been exposed to antibiotic- supplemented feeds (control group), and from fish on an integrated farm, fed for 6 wk with manure of chickens that received tetracycline-supplemented and chloramphenicol-supplemented feeds. E. coli was...

The prevalence of E. coli isolates from fish and chickens on the integrated farm that were resistant to tetracycline and chloramphenicol, to trimethoprim-sulfamethoxazole, gentamicin, ciprofloxacin and amoxicillin were significantly higher (p0.05), indicating that exposure to antimicrobials was not required for the occurrence and maintenance of resistant strains.

A comparative study on the antimicrobial resistance of Escherichia coli isolates from chickens and fish grown on integrated and traditional fish farms
description Escherichia coli was isolated from fish grown in a pond that had never been exposed to antibiotic- supplemented feeds (control group), and from fish on an integrated farm, fed for 6 wk with manure of chickens that received tetracycline-supplemented and chloramphenicol-supplemented feeds.
