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

Paper summary generated by OpenAI: This study presents a comprehensive global atlas of antimicrobial resistance (AMR) in Salmonella, analyzing 208,233 genomes from 148 countries between 1900 and 2023. The findings reveal significant geographical variations in AMR levels, particularly increasing in serovars such as Agona and Dublin, while others like Schwarzengrund showed declines. The research identifies key drivers of AMR, including antibiotic consumption, agricultural practices, climate, urbanization, and socioeconomic factors. This high-resolution genetic atlas enhances our understanding of the transmission dynamics and evolutionary trajectories of Salmonella, providing critical insights for public health strategies.
