The mac sample was shown to be vulnerable to amikacin and Arikayce. Because I was recently diagnosed with Parkinson's, my ID doc wants me to use an inhaled version of the medication instead of IV since there is less of a chance of neurological side effects.
Regarding the new research article posted by Carolyn, there is a recent mouse study that showed that the diabetes drug Metformin could be beneficial against MAC. What works on mice doesn't always help humans, but perhaps someone will fund a clinical trial.
