Stenotrophomonas maltophilia

General Susceptibility

TMP-SMX is probably the most reliable agent, followed by ticarcillin-clavulanate.

Other drugs such as ceftazidime, aztreonam, levofloxacin, moxifloxacin, and tigecycline are sometimes used if susceptible.

Minocycline has excellent in vitro activity but limited experience.

Intrinsically resistant to beta-lactams.
