The search for new pathogens leads scientists to analyze environmental DNA in various settings, providing insights into the microbial world and aiding early outbreak detection. In short:Researchers use environmental DNA (eDNA) to identify a diverse range of microbes in New York City's subway system, revealing a hidden world of bacterial life. The COVID-19 pandemic has spurred advancements in eDNA research, which now allows for the rapid identification of pathogens in water, soil, and air. The potential of eDNA extends to developing early warning systems for disease outbreaks by monitoring high-risk environments where humans and animals interact. — Erik Karlsson, virologist at Institut Pasteur du CambodgeWhy this matters:Understanding and monitoring eDNA can provide early alerts for pathogen outbreaks, contributing to faster responses and potentially saving lives.
