Summary

Researchers at Mayo Clinic are recruiting 5,000 adults to study how the trillions of microbes living in and on our bodies influence health and disease. Participants will provide samples so scientists can compare the types and amounts of different microorganisms. This observational study aims to better understand the role of the microbiome in conditions like digestive disorders, without testing any new treatments.
