I see a pulmonologist at Mayo in Rochester, MN. I had a CT scan prior to the sputum test and that’s why he ordered the tests. I do cough up sputum (it is usually clear, murky, or slightly blood stroked, but not yellow or green) after respiratory therapy. Information is limited on the internet but here’s what my doctor told me: 2 of the 3 cultures showed mycobacterial current-gordornia polyisoprenivorans, which he called and does not cause disease unless there is an immunodeficiency (which I do not have)........I am stable as far as no illness is concerned and I am due to see him again in 6 months. I do experience ongoing fatigue and some chest pain (this is minimal). What do you think?
