Asthma- Steroid Inhaler- Do They "Feed" Cpn

I saw a blog a while back and wanted to ask does steroid inhalers "feed" Cpni.  I read a little bit of the Cpn Handbook and it said something about steroids possibly suppressing the immunei system but I was wondering if more research is out there about this and if steroids actually are conducive for Cpn growth?
