Poop pills vs. superbugs: new hope against Antibiotic-Resistant infections
NCT ID NCT05742074
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tested whether transplanting healthy donor stool (fecal microbiota transplantation, or FMT) into the gut could wipe out multidrug-resistant organisms (MROs) in 83 adult carriers. The goal was to prevent future hard-to-treat infections. Participants swallowed capsules containing either donor stool or a placebo, and researchers checked rectal samples for MRO clearance after 8 and 16 weeks.
