Decreasing antimicrobial resistance in representative UK livestock species was associated with reduced total sales of antimicrobials in the last decade

Antimicrobial resistance (AMR) is a global health crisis that contributes to human mortality, with livestock being a reservoir of AMR. Since 2014, UK surveillance schemes for antimicrobial use (AMU) have decreased, allowing for a study to assess the relationship between AMU and AMR. The study found that a decrease in detectable AMR phenotypes in E. coli was associated with a decrease in total sales of antimicrobials, and a decrease in multidrug resistance prevalence.
