Cdiff is a clearly defined and known infection that can probably occur to a vast majority of the population if they are acutely infected, and seems to be isolated to the gut with little involvement of other body systems unless the infection gets out of control.Sounds like you've been through the wringer, like me. One question is, why do CDiff patients recover after just a few implants, and yet we ME/CFS patients do not?
ME is a much more complex illness that seems to be more tied to a genetic pre-disposition of sorts and includes most body systems and most body organs to all it's sufferers to some degree or the next.
The "one and done" FMT approach to Cdiff seems too easy a fix for such a complex illness such as ME.
That's my opinion.
