It may be that as Will gets farther out from the various lymphomas and pneumonias and his health stabilizes more and (we hope!) improves more, he'll be able to clear the pseudomonas as he was able to pre transplant. But, it will be harder this time because of the immune suppression drugs he needs to take to prevent rejection. In the meantime, he tries to keep it under control with daily airway clearance and periodic IV and inhaled antibiotics.
It appears that the pseudomonas makes a home in Will's sinuses and goes from there into his lungs. Sinus surgery has been discussed but the results seem uncertain, especially for someone with CF. If any of you CFers out there have experience with sinus surgery one way or the other, please let me know. Thanks.
PS - I took the pseudomonas photo from the wikipedia site, which says it is P. aeruginosa colonies on an agar plate.
