Antimicrobial use in agriculture can breed bacteria resistant to first-line human defences

Published on April 21, 2023

A new study led by the University of Oxford has shown that overuse of antimicrobials in livestock production can drive the evolution of bacteria more resistant to the first line of the human immune response. The results, published today in the journal eLife, indicate that farmed pigs and chickens could harbour large reservoirs of cross-resistant bacteria, capable of fuelling future epidemics.
