Overview

Analysis shows extended-spectrum beta-lactamase E. coli persists in chicken ceca, suggesting implications for antimicrobial resistance spread.

Key Points

  • Some ESBL-producing E. coli isolates persisted in chicken ceca for days, influencing antimicrobial resistance dynamics.
  • Throughout the study, pig and cattle-associated isolates were most consistently recovered, indicating specific host contributions.
  • Utilizing a chicken cecal fermentation model enabled examination of ESBL plasmid transfer among diverse E. coli isolates.
  • Understanding these persistence mechanisms might address the larger issue of antimicrobial resistance in animal and human health.
