Evaluation of dalbavancin alone and in combination with β-lactam antibiotics against resistant phenotypes of Staphylococcus aureus

Abstract

Dalbavancin was active against all MRSA strains tested, including heteroresistant vancomycin-intermediate S. aureus, vancomycin-intermediate S. aureus, daptomycin-non-susceptible and linezolid-resistant isolates. The synergy demonstrated against these organisms supports the use of dalbavancin in combination with β-lactams against resistant phenotypes of S. aureus. Further evaluation is warranted.
