This study evaluated telavancin activity against 3868 Staphylococcus aureus and 1003 coagulase-negative staphylococci (CoNS) collected from 33 European hospitals (2009-2010). Studies of telavancin potency included analysis of strains with decreased susceptibility to glycopeptides. Telavancin (MIC50/90, 0.12/0.25 mu g/mL) showed high activity against S. aureus and CoNS, regardless of the stratification analysis performed (year sampled, infection source, or methicillin susceptibility). In addition, telavancin (MIC50/90, 0.25/0.5 mu g/mL) retained activity against S. aureus isolates with higher vancomycin (MIC, 2 mu g/mL) or teicoplanin (MIC, 2-8 mu g/mL) MIC results. Overall, telavancin exhibited higher potency (at least 2-fold greater) than tested comparators (vancomycin, daptomycin, and linezolid) against European staphylococci. Alongside published clinical data, the telavancin in vitro activity observed against these pathogens supports this drug as an option for treating S. aureus infections in Europe, including those infections caused by strains with decreased susceptibility to vancomycin and/or teicoplanin.
