Intestinal t cells from CD patients react more vigorously to MAP than to commensal bacteria, and react more vigorously to MAP when compared to UC or controls' intestinal t cells.

Note the discussion of NOD2 and MDP, which is present in bacterial cell walls, and how mycobacteria produce a 'special' form of MDP that is more potent at inducing pro-inflammatory responses.  And how cows with NOD2 polymorphism more susceptible to MAP infection.  So think about it: 95-99% of people with NOD2 do not develop disease, and yet they all have commensal bacteria; must there not be something else required other than commensal bacteria to trigger disease?
