I sometimes culture S. Maltophilia, but I don't think I have cultured it in a while. No, I haven't been isolated. They treat it with whatever antibiotic it is susceptible to. I am usually on oral Bactrim and I go on differnt combinations of IVs every few months.
I was isolated for a while when I was diagnosed with a mycobacteria, but it ended up being Avium not TB, so they un-isolated me. I had to take 3 kinds of oral antibiotics for 2 years to get rid of it.
