Just a comment, I made a bet with myself when I saw the first post that it would show an increase in fusobacteria. These species have been implicated in possible etiology of colorectal cancers. They are known to form biofilms with other harmful species. Has anyone else noticed a similar association with other culprits named in association with Crohn's disease? Next question: how do we tell consequences of immune dysfunction from original causes? We may be able to interrupt pathology without knowing, but it would be very nice to know how this came about.
