DS cultured it about 9 years ago and the doctor really wasn't concerned as it was shown as rare, I don't recall what it was sensitive to, but doctor didn't change any of his meds --- was already on Tobi due to a culture of pseudo a few years before, but no longer cultured and azithromycin. It didn't show up on the next culture and then shortly afterwards DS was hospitalized for an obstruction and the doctor decided to do an IV cleanout since he was inpatient anyway and he hasn't cultured it since. I do recall I couldn't find any info on it and probably posted here about it.
