scoop. Yes. The first time it happened I was elated that I was rid of these bacterium but alas that was not the case. In a few months I cultured MAC and 4+ pseudomonas while still doing airway clearance. I found out that pseudomonas can colonize so I'll always be fighting it. We have to be strong and keep doing everything we can to control, (push down) this enemy. I hope that's not overly dramatic but... Blessing on you all.
