Just resurrecting an old thread as opposed to starting a new one! I understand the concept that bacteria is everywhere and that it's essentially unavoidable to culture various strains...however, given that B. Cepacia only affects approx. 3% of CFers, do any of you who culture positive "know" where you acquired it? Perhaps a question without an answer other than bacteria are everywhere. Just thought I'd ask! I do know that some carriers acquired it from other CFers....how many of you have been exposed to others with CF that cultured cepacia prior to culturing positive yourself?
