Funny you should ask Ling. I have been looking into Phages lately. I know about the Phage study for Pseudo. A friend of mine is going to participate in one of the study locations. There is a location about 4 hours from me but I do not qualify with their criteria. My BMI is too low. Also it would be very hard on me to make the repeated trips. The Phages do not necessarily get rid of Pseudo in all cases. Or you might have to repeat treatment for some period of time to clear it. But it is very hopeful. They are studying the use of Phages alone and in conjunction with inhaled antibiotics. I wish we had access to them NOW! These things take so long to get approved.
