If anyone has been diagnosed with Mycobacterium abscessus (aka MABs) here is a clinical study you might be interested in. https://ntmclinicalstudy.com/ I have had this version of MAC show up in my sputum samples on 3 occasions over the last 3 years. Most recently negative. It has been over 2 years since taking antibiotics. So I continue with nebbing 7% saline and using the Aerobika.
