Some patients are having astounding success with fecal transplants, and a DIY community is growing. BBC reports:

There is growing recognition that faecal transplant is the best way to treat [some] patients. In the first randomised trial of the technique published in the New England Journal of Medicine last year, 94% of patients were cured by the treatment, whereas a course of antibiotics cured just 27%. The disparity was so huge that the researchers stopped the trial early, on the grounds that it was unethical to deny the better cure to the cohort assigned antibiotics.
