Rising temperatures could be driving up antibiotic resistance in soil, 11-year study finds

Phys · · 657 words · By Sanjukta Mondal
climate_change Public Health Antimicrobial resistance

An 11-year study published in Nature suggests that long-term climate warming increases the abundance and mobility of antibiotic resistance genes in grassland soils. The research indicates that higher temperatures favor specific bacteria that carry these genes, potentially complicating the management of crop diseases and public health.
