Hi Rachael!
It's so nice to e-meet you. I'm not sure how long it took to get diagnosis from the bronch because I was a kid. I did go UNC Chapel Hill (They are the leading researchers on PCD in the US) last year to participate in the research and had the diagnosis reconfirmed through a nasal scrape and found out right away. That is only because it didn't need to be sent anywhere. It was kinda cool. They put my sample right under the scope I was able to view it. Then they showed me a video of normal cilia...yikes what a difference. The part that took several weeks was finding out my cilia defect. They actually slice the cilia like a cucumber(cross section) , photograph it, blow it up and can see what the defect is.
You can have PCD without situs inversus. PCD(primary ciliary dyskinesia) is the main disorder. There are subsets of PCD like Kartageners Syndrome,which is PCD with situs inversus. I wasn't surprised to hear about the atelectasis in the middle lobe. The scarring is from recurrent infections. Have you been tested for CF? Have you had any other respiritory issues prior to January. Any sinus or ear troubles?
I've cultured out the same two things as you. More often than not it's the h-flu for me. I'm on yet another round of antibiotics. I usually do not have such a hard time kicking these little buggers but this one is just being a pain in the behind

Hope I haven't bored you to tears

) If you have any questions please feel free to ask. I hope your biopsy comes back negative.
Sending many positive thoughts your way,
Lynn
