Exploring environmental DNA's role in pathogen detection

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.

Rene Ebersole reports for Undark.

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.

Why this matters:

Understanding and monitoring eDNA can provide early alerts for pathogen outbreaks, contributing to faster responses and potentially saving lives. This research bridges the gap between environmental science and public health, offering new tools for combating infectious diseases.
