Summary

This study aims to create a central bank of stool donors to help treat diseases linked to gut bacteria. Researchers will screen healthy adults aged 18-80 living near Stanford to find eligible donors and study their microbiome, immune system, and diet. The goal is to better understand what makes a good donor for future therapies.
