Abstract

The activity of telavancin was compared with vancomycin against methicillin-resistant Staphylococcus aureus (MRSA) in planktonic culture and biofilms grown using a range of in vitro models. Antibiotic efficacy was determined using 24 clinical isolates, including healthcare-associated (HA)-MRSA, community-associated (CA)-MRSA and isolates with reduced (intermediate) susceptibility to vancomycin (VISA). Activity against biofilms was compared using three models: 96-peg plates, 96-well flat-bottom plates and a flow-cell system. Cell death was evaluated using a metabolic dye and Live/Dead staining.
