I stumbled across this while looking for examples of patients of Dr Borody (the godfather of FMT). Bill Curnow is a retired Australian Architect & Professor who has Parkinson's and had impressive improvements from antibiotics. He also later had FMT but said that did not make a difference.
Anyway, Bill has a web site where he shares his story and his theories on PD and it is fascinating. It is a single page and you just start at the top and scroll down to read everything. It is arty also: biomiclife.com/
