In Vitro Activities of Tigecycline and Eight Other Antimicrobials against Different <i>Nocardia</i> Species Identified by Molecular Methods

Abstract

The in vitro activities of tigecycline and other antimicrobials against 51 isolates of Nocardia spp. were evaluated. MIC(90)s and MIC ranges were as follows: tigecycline, 4 and < or =0.06 to 8 mg/liter, respectively; minocycline, 2 and < or =0.06 to 2 mg/liter, respectively; linezolid, 1 and < or =0.06 to 2 mg/liter, respectively; moxifloxacin, 2 and < or =0.06 to >64 mg/liter, respectively; ertapenem, 32 and < or =0.06->64 mg/liter, respectively; imipenem, 2 and < or =0.06 to >64 mg/liter, respectively; meropenem, 8 and < or =0.06 to >64 mg/liter, respectively; amikacin, 1 and < or =0.06 to 32 mg/liter, respectively; and trimethoprim-sulfamethoxazole, 1/19 and < or =0.5/9.5 to >2/38 mg/liter, respectively.
