@trissi Trissi, I hope you will take the time to read over older posts, especially those by @katemn, she had lots of good info. Also, I recommend that you Google all that you can on the subject of avium bacterium and pseudomonas. Knowledge is power. Do you know if you also have a condition/disease called bronchiectasis? It commonly goes hand in hand with MAC infections. Feel free to ask questions or share your experiences.
