Often colonizing hospital equipment and environment.
Treatment
TMP/Sulfa has been the treatment of choice (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.
