Climate change linked to rising antibiotic resistance in Salmonella

Antimicrobial resistance (AMR) is mainly driven by the overuse and misuse of antibiotics, which allows resistant bacteria to survive and spread. However, rising temperatures and changing rainfall patterns can influence how bacteria survive, mutate, and spread, potentially increasing the exchange of antibiotic resistance genes. While previous studies have linked higher temperatures to greater levels of resistant bacteria, global quantitative studies on this relationship have been limited.
