It's not a dumb question. <img src="">
Throat cultures will also sometimes only turn up 'normal flora' since they generally contain no sputum from deep in the lungs; if they got a sample from deeper in the lung sometimes more would turn up. It's not uncommon for quite some time to go by and at least some of the cultures to show 'normal' results, and maybe staph or h.flu to be the only other findings. There are several bugs that only require treatment when they are sick, and things like the tube infection wouldn't cause changes on the sputum culture.

I guess it will change when we start preschool
Also, I was told - not many healthy people have only natural flora so its not suprising that our kids usually culture something. The question is what and does it go into lungs I guess....</end quote></div>
Things won't necessarily change upon starting school. Yes, our kids will likely get sick with more viruses, etc, but they do not 'catch' cf bugs from the general population- they are already exposed to bugs like PA, staph and many others in the water, soil, other surfaces and some even in the air on a daily basis and healthy people don't have resp systems hospitable to being colonized with cf-specific ones like PA. So people that kids with CF are exposed to in the general population aren't the threat when it comes to being colonized- others with CF or compromised immune systems can present a problem, but not typical kids.

well, viruses weaken the respiratory system's defenses so getting them more often MIGHT put ppl with CF at a higher risk of culturing CF bugs, b/c their respiratory system is more vulnerable during the time of illness. I agree though that ppl kids are exposed to in school are not a threat and just being in contact with them should not change anything
