@wesbig Every day is something new here! Like you I went diving to learn about this mycobacteria, only to learn it was first isolated about a dozen years ago. Best I could find was the genomic classification here:

Nothing about infectious capacity in humans. So a few questions for you...
Did they tet more than one sputum sample? Were any other strains isolated in the specimens? Do you have symptoms - cough, fatigue, weight loss, nodules or cavities evident on a CT scan?
If the answers to all these questions is no, I personally would be looking for someone who specializes in treating MAC, quite possibly Mayo, National Jewish Health or University of Texas, Tyler to name a few.
I see you have been a member for a few years, have you been treated for MAC before?
