This seems like a very important finding. It confirms earlier studies about reduced beneficial bacteria in the micorbiomes of Crohn's and chronic ulcerative colitis patients, which is something that was also recently found in Dr. Hanson's study of ME/CFS patients.
Crohn's study:
ME/CFS study:
What might be particularly important is the interplay between various bacteria and (now) fungi involved. It would be remarkable if it turned out that Crohn's, CUC and ME/CFS were manifestations of similar, self-sustaining imbalances, perhaps distinguished by which gut microbes are involved.
