@alleycatkate I agree with you. I have not been on any antibiotics since diagnosis in fall of 2014. I'm doing great and condition of my lungs is not deteriorating based on one CT scan and multiple chest X-rays. Although I have not had another sputum test, I do believe I'm cleared of MAC for now. I'm making every effort to eat healthy and stay active to stake MAC infection out. But with bronchiectasis, you just never know. Got to be vigilant at all times Can't afford to take eyes off for even one day.
