Is there such a thing as a fecal transplant? what's it for? please illuminate me.

C diff: Clostridium difficile (c diff) colitis is often very difficult to treat fully, as it is prone to relapse. Fecal transplant is introducing stool from another person (hopefully that lives in the same house, and without recent exposure to antibiotics) to repopulate the bowel flora to prevent c diff from growing. It is highly successful, but understandably distasteful.

Fecal transplant: It is not the best terminology, but it exists. It is more like a stool enema and it is used to recolonize the colon with normal bacterial flora in cases of resistant clostridium difficile colitis.
