Yes the consistancy changed to a buggery, stretchy consistancy and white. (back in 2008) I had never seeen stretchy stuff come out of my lungs. It has been bulky, blobs for as long as I can remember. Unfortunately, I have not seen flora changes at any point. I still culture both PA and MRSA and my consistancy is still the same as my usual cf mucus now but I have few days a year where I see khaki color which was becoming increasing frequent prior to 2010.
You all have great questions!
