Antimicrobial resistance in livestock systems

Antimicrobial use and overuse in livestock production is a key driver of global antimicrobial resistance (AMR) development. Although different antimicrobials are typically used in humans and animals, resistance genes can spread horizontally in the environment — even to bacterial populations with no previous exposure to antimicrobials.

Now, a genomic analysis of Escherichia coli samples taken during the past 50 years from livestock production sites in China reveals patterns of AMR spread and identifies plasmids that conferred increasing resistance for critically important veterinary and human antimicrobials. Policy actions informed by the biology underlying AMR are urgently needed to curtail the use of antimicrobials in livestock production and limit the global spread of AMR.
