Those resistant bacteria are then free to thrive and spread. Drug-resistant bacteria in the soil, in water, in sewageĭrug-resistant microbes multiply when a course of medication, such as an antibiotic, kills off susceptible bacteria and spares the few who happen to be hardier. "The analysis suggests that PM2.5 is one of the leading factors driving clinical antibiotic resistance," says Chen. ![]() Ultimately, they say the air pollution association accounts for some 12% of the increase during that time, adding up to 480,000 premature deaths and economic costs of $395 billion in 2018 alone. Using data from published studies as well as disease surveillance networks, clinical trials and diagnostic labs, the researchers tried to untangle which factors were most important in driving up global antimicrobial resistance over the period from 2000-2018 (CQ). The team found a strong association between particulate air pollution [in a given country and reports of clinical antibiotic resistance. ![]() The new research, from a team at Zhejiang University in China and the University of Cambridge in the United Kingdom, set out to quantify the role of air pollution in the growing global AMR problem. It has long been suspected that particulate air pollution could transport antimicrobial-resistant bacteria that leak into the environment from farming, aquaculture, wastewater treatment and hospitals.
