Activities of dalbavancin in vitro and in a rabbit model of experimental endocarditis due to Staphylococcus aureus with or without reduced susceptibility to vancomycin and teicoplanin.

Abstract

For the treatment of rabbit endocarditis, dalbavancin given once daily (10 mg/kg of body weight for 4 days) or as a single 40-mg/kg dose was active against Staphylococcus aureus with or without reduced susceptibility to glycopeptides, as expected from its good in vitro activity, even in broth supplemented with 90% serum and given its prolonged elimination half-life.
