@bolso1 The thing with BCG and TB is ( and I’m sure you know this) is that it is used in third world countries especially China and is a live virus unlike in the US. It can cause positive TB skin tests which it does in two of my six Chinese children. They were given Isoniazid for nine months to confirm no active disease even though their lungs were clear. You are probably correct about the saline and bronchiectasis only as MAC loves water. That is something I have questions about. At this point I just want something to cure us all! irene5
