Yes, it did stop on its own for the most part. This is an intriguing little nasty bacteria. I have read some new studies from Universities studying Tuberculosis and They have developed a mimic bacteria that when the TB virus morphs into it, the good bacteria will eat the TB. This is just the beginning, may take awhile to get out. I really think the medical community needs to develop an Immunotherapy treatment for MAC. The body was created to fight this Avium complex bacteria. When the immune system is compromised it seems to have a hard time getting rid of the MAC that hides deep in the lungs and has a hard protective shell. We need to develop a way to boost our own immune system to fight this bacteria get rid of the antibiotic treatment!! Praying for BIG help on this.
