Scientists probe why poop transplants work for gut infections

NCT ID NCT05739825

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tracks how fecal microbiota transplantation (FMT) alters the gut microbiome in 20 adults with recurrent Clostridioides difficile infection. Researchers will analyze stool samples before and up to 90 days after FMT to see which bacteria take hold. The goal is to understand why FMT is so effective, not to test a new treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Fecal microbiota transplantation (FMT) from healthy donors
What this could lead to
If successful, this could help explain why FMT works for recurrent C. difficile infections, potentially leading to better treatments.
What could go wrong
This is a very small, early-stage study (20 people) that only observes microbiome changes. It does not test a new treatment or measure clinical outcomes directly.
