Worldwide summary of telavancin spectrum and potency against Gram-positive pathogens: 2007 to 2008 surveillance results.

Telavancin was approved in the United States and Canada for the treatment of adult patients with complicated skin and skin-structure infections (cSSSI) caused by susceptible Gram-positive isolates. In this study, telavancin and comparator antimicrobial activities were determined against a total of 24,017 clinical isolates, including Staphylococcus aureus, coagulase-negative Staphylococcus spp. (CoNS), Enterococcus spp., and various Streptococcus spp. Overall, telavancin was highly active across all geographic regions for S. aureus (MIC(50/90), 0.12/0.25 microg/mL; 100.0% susceptible), CoNS (MIC(50/90), 0.12/0.25 microg/mL), vancomycin-susceptible Enterococcus faecalis (MIC(50/90), 0.25/0.5 microg/mL; 100.0% susceptible), Enterococcus faecium (MIC(50/90), 0.06/0.12 microg/mL), Streptococcus pneumoniae (MIC(50/90), < or =0.015/0.03 microg/mL), viridans group Streptococcus spp. (MIC(50/90), 0.03/0.06 microg/mL; 100.0% susceptible), and beta-hemolytic Streptococcus spp. (MIC(50/90), 0.03/0.12 microg/mL; 99.8% susceptible). Telavancin had potent activity against vancomycin-nonsusceptible, teicoplanin-susceptible (VanB) E. faecalis (MIC(50/90), 0.25/0.5 microg/mL) and E. faecium (MIC(50/90), 0.06/0.25 microg/mL). These in vitro results show continued activity for telavancin, which represents an important alternative available for treating cSSSI.
