This is a really interesting discussion. When I was first diagnosed in 2011 I was told that showering was not a problem but to avoid swimming and hot tubs. I agree that MAC is everywhere in the environment and not to get too concerned. Maybe shorter showers and avoid misters in Florida! I am very confused about the concept of colonization and hope someone can enlighten me. They recently found a very rare organism called S. maltophilia in my culture and tried to reassure me that it was a colonization and not an infection. So when is colonization a good thing and when is it a bad thing? I just watched Dr. Huitt's presentation and one of the ways to determine if one should treat was to count the number of colonies, the magic number being 50.
