title: In vitro activities of telavancin and vancomycin against biofilm-producing Staphylococcus aureus, S. epidermidis, and Enterococcus faecalis strains.
abstract: We investigated the activities of telavancin and vancomycin against biofilm-producing Staphylococcus and Enterococcus strains. At clinically attainable concentrations, telavancin was active against bacteria embedded in biofilm (minimal biofilm eradication concentration [MBEC], 0.125 to 2 microg/ml) and inhibited biofilm formation at concentrations below the MIC. Vancomycin did not demonstrate the same activity (MBEC, > or =512 microg/ml) against Staphylococcus aureus and Enterococcus faecalis. Telavancin may have a unique role in biofilm-associated infections.
