So after a few years of dealing with this I have come to realize that MAC can come and go for those of us with bronchietasis. This is why the daily routine to keep our lungs clean is so important; because we don't clean mucous like the rest of the world and this will cause MAC to come back. Things like indoor swimming pools, hot tubs, and gardening are likely triggers for me to get reinfected. Not to mention lack of sleep, and getting off my daily exercise plan and good eating. So I do my daily routine: 7% saline nebs with my aerobica ( by the way I often do my neb in my car on the way to work for convenience and consistency); vest therapy when I feel tight; and intermittent sputum sampling via my pulmonologist to keep monitoring. And thank you for the dry bronchiectasis comment; because thinking I lean more that way. Hope this helps.

lindac11208, I have that same situation. I really hope someone answers your question!
