Few years ago sputum culture showed MAI. Was on Big 3 for a couple of years (at end clofazamine substituted for ethambutol due to vision problems). Last culture showed 50 colonies of chimaera. Wondering how many of you had chimaera show up; were you treated; if so, what and for how long? Anyone simply have it go away with just airway clearance techniques? Had 5 colonies of m.abscessus show on another culture. Anyone with that type of experience as well?
