What can you tell me about fecal transplants?

Mainly for C. diff: Stool transplants are being done primarily for refractory, recurrent C. difficile infection not responding to traditional antibiotics. It should ideally be done by a GI doctor (traditionally with a colonoscopy). With a large focus on gut bacteria, studies have been examining whether stool transplant helps other conditions (i.e, irritable bowel, IBD, obesity, etc)
