How might Stenotrophomonas maltophilia be treated?

S. maltophilia is resistant to many antibiotics. The recommended therapy is trimethoprim-sulfamethoxazole (also called co-trimoxazole, or TMP-SMX). The duration of therapy depends on the site of infection. Other medications to which the organism is usually sensitive include meropenem, ticarcillin-clavulanic acid, levofloxacin, gatifloxacin, moxifloxacin, minocycline, tigecycline, polymyxins (ie, colistin sulfate), and rifampicin.[1][2] Combination therapy may be necessary in life-threatening cases.
