Hi ziel, and thanks for your post. I am hopeful others in the community, who have experience with this bacteria, Mycobacteriaum avium complex, (MAC), will chime in and share their experiences here.
I did want to wish you 'good luck!', as you await the results of the culture. Please do check back and let us know how this all turns out for you.
Wishing you well,
Leon (site moderator COPD.net)
