A global atlas and drivers of antimicrobial resistance in Salmonella during 1900-2023

A study analyzing 208,233 Salmonella genomes in 148 countries between 1900 and 2023 found that antimicrobial resistance (AMR) in Salmonella varied globally, with increased levels across six continents. Factors contributing to AMR development include antibiotic consumption, agriculture, climate, urban life, health, and socioeconomic factors. The study presents a globally high-resolution genetic atlas of Salmonella and identifies factors driving its rise, providing valuable insights into the transmission dynamics and evolutionary trajectories of the disease.
