Summary

This study tested fecal microbiota transplant (FMT) in 24 adults with recurrent Clostridium difficile infection (C. diff) that didn't get better with standard antibiotics. FMT involves placing healthy donor stool into the patient's colon to restore good bacteria. The goal was to see if this treatment reduces the need for repeat transplants, surgery, or more antibiotics.
