I've cultured pseudo now for about 16 years now. Like Luke said, it is the thorn in our paws. Usually we are on TOBI once month on, one off, or they may try inhaled Colymycin or oral Cipro. It all depends on what works for your kids. What works for some, does not work for all. All I can say is, be very dilligent with physio so that the pseudo has a less chance of spreading too much. Once you're cultured pseudo a few times, you cannot get rid of it, but it does go dormant every once and a while. Sometimes you will culture it, and sometimes not because it has gone to "sleep". If you have any other questions, don't hesitate to ask!
