Summary
This longitudinal ecological study analyzed 488,232 Salmonella genomes to investigate the link between climate change and antimicrobial resistance genes (ARGs). The research found that warming temperatures and shifting precipitation patterns are associated with rising ARG abundance in Salmonella. Under high-emission climate scenarios (SSP2-4.5, SSP3-7.0, and SSP5-8.5), these trends are projected to further exacerbate antimicrobial resistance risks. The study provides global evidence that climate change accelerates the dissemination of AMR in zoonotic diseases and highlights the need to integrate climate considerations into AMR surveillance and stewardship strategies.
Key quotes
· 3 pulledThis longitudinal ecological study aimed to link climate change to ARGs using multiple regression models.
Warming and shifting precipitation patterns are associated with rising ARG abundance and are projected to further exacerbate AMR risks under high-emission scenarios.
These findings highlight the need to integrate climate considerations into AMR surveillance and stewardship, providing a quantitative basis for climate-informed strategies to restrict future resistance escalation.
