microbioma.org is trying to solve the donor problem. We need more people to start spreading it in locations where "superdonors" would be. Gyms, universities, community colleges, to professional athletes if possible, etc..
Regarding having to continue doing FMTs, it might be a donor problem or it might be an issue where we're not changing the mucosal microbiome. In which case we'll have to figure out how to do that. There are a few possibilities that will hopefully be looked into soon.
It seems an issue of both compatibility (not all donors are suitable for all recipients) and muscosal or resident gut bugs resilience to be colonized by new compatible & healthy bugs. Its extraordinary complex. Also some other conditions do apply, some people with MCAS active have issues getting new gut flora while these same patients after putting under control their MCAS can accept new gut microbes even from the same donor and fully recover (as far as I know there are two cases recorded of failed FMT due to MCAS, and successful after MCAS under control). Most likely many other parameters that prevent FMTs from succeeding we still don't know and where all research and efforts should be put on.
Microbioma.org compatibility and patient tailored solution algorithm we are developing aims to shed light there.
