Group Owner Comment

Mycobacterium avium complex (MAC), of which paratuberculosis is a subset,
causes serious disease in people who are immune deficient (i.e., AIDS
patients). In my opinion, these bacteria are considered non-pathogenic to
humans not because they only cause disease in people who lack resistance.
The rubella virus only causes measles in people who lack resistance. MAC
is considered non-pathogenic because the people who lack resistance
represent a minority.
