Nosocomial infections (cancer patients (PubMed)), intravenous drug user and cystic fibrosis.
Often colonizing hospital equipement and environment.
Treatment
TMP/Sulfa has been the treatment of chice (there may be synergy when ticarcillin/clavulanate is added) or minocycline (Pubmed) or perhaps cefepime, often resistant to quinolones, aminoglycosides, carbapenems, and other third generation cephalosporins (PubMed).
Tigecycline may be sensitive (PubMed).
Given all the resistance, get susceptibilities.
