Hi,
I have cultured stenotrophomonas maltophilia also, in addition to staph, pseudomonas, aspergillus and mycobacterium abcessus. The m. abscessus was a significant problem in the past and I received many months of iv abx for it. Luckily I haven't cultured it for a few years. Right now I am only culturing the stenotrophomonas and it seems to be the thing that is causing me problems with slowly declining pfts (2%/year- Fev1~50%). It, unfortunately, is resistant to all but a couple abx. All things considered, I am doing pretty well. I am able to exercise and am fairly active for an 'old' person!
