It's 4 years now since this thread was started following an article in New Scientist. The magazine is still reporting on faecal transplantation [1].

In a recent edition Parkinson's is mentioned in passing, but no examples of FT's use in this area are given.

Talking generally, the good news is that "[faecal transplants] are a lifeline for people with recurrent Clostridium difficile infections of the gut, which cause diarrhoea and fever, and can be fatal. These infections can recur after antibiotic treatment, but are cured 90 per cent of the time after a faecal transplant."

The bad news is that the transplant may pass disease to the recipient.

Given this more effort is being made to screen donors, with ironically Parkinson's being a reason for exclusion.
