A new study in Nature Microbiology reveals that drought conditions select for and enrich antibiotic-resistant bacteria in soil, creating a potential link to increased antibiotic-resistant infections in hospitals worldwide. Researchers found that dry soil consistently promotes resistance genes, suggesting climate change-driven droughts could exacerbate the global antibiotic resistance crisis. This adds an environmental dimension to the problem beyond clinical antibiotic overuse.
Background
Antibiotic resistance is a growing global health crisis where bacteria evolve defenses against antibiotics, making infections harder to treat. While overuse in healthcare is a known driver, environmental factors are less understood.
