It’s known that gut microbial diversity is essential for donor success, particularly in treating conditions such as inflammatory bowel disease (IBD).

But researchers at the University of Auckland, New Zealand, believe faecal transplant success rates could be boosted by seeking out so-called super donors for specific patients.

A literature review suggests there is likely no “one stool fits all” approach to transplants, the team says.

They’ve identified several studies where one donor has contributed disproportionately to successful outcomes.
