Official title: Mechanisms of Fecal Microbiota Transplant Protection from Recurrent C. difficile
Funded at University of Virginia · NIH-11243646 · Data updated 2026-11-12
This project aims to discover how fecal microbiota transplant (FMT) works to prevent C. difficile infections from coming back in patients.

Who could benefit from this research
✓Could help
Patients who have experienced recurrent C. difficile infection and are undergoing or considering fecal microbiota transplant would be ideal candidates for this type of research.
✕Less likely to help
Patients without recurrent C. difficile infection or those not receiving FMT would not directly benefit from this specific research.
What this research studies
The project wants to understand how fecal microbiota transplant (FMT) helps patients avoid recurrent C. difficile infections. Researchers will look at colon biopsies from patients before and after they receive FMT to see changes in their gut. They will also use special mouse models to learn more about how FMT affects the body's signals, immune system, and gut repair processes. The goal is to find out exactly how FMT protects against these infections by focusing on the patient's body rather than just the bacteria. This work builds on previous clinical studies involving humans undergoing FMT.
Why it matters
Potential benefit: If successful, this work could lead to new or improved treatments for recurrent C. difficile infection by targeting specific body systems, potentially even helping with other conditions like inflammatory bowel disease.
How similar studies have gone: While FMT is a known effective therapy, this project explores new and innovative ways that FMT impacts the patient's body rather than just the bacteria, challenging previous ideas.
