Good morning, and welcome to Mayo Connect and the MAC & Bronchiectasis group. We are people living with a wide variety of diseases and conditions, who support each other along the way. We try to be informed medical consumers, and our own best advocates in our care. We are not medical professionals, so not able to provide medical advice. We can tell you what has worked for us (or not) and provide you with information and conversation about your questions.

Since you are new to us, I would like to ask a few questions. When you say you have had Mycobacteria Chimera for over a year, do you also have a lung disease like COPD, Asthma or Bronchiectasis? When you recently had a bronchoscopy, did you mean "no improvement" or no M. Chimera in a sputum culture?

It is typical to continue to treat mycobacteria infections for one year after the bacteria does not show in a culture, to eradicate it as much as possible?

Let me know if I can answer any questions for you.
Sue
