Abstract
This study evaluated the in vitro antimicrobial activity of telavancin against a large collection of Gram-positive pathogens of clinical importance, which were collected worldwide from 2015 through 2017, including methicillin-resistant Staphylococcus aureus (MRSA), coagulase-negative staphylococci, Enterococcus spp., β-hemolytic streptococci (BHS), Streptococcus pneumoniae, and viridans group streptococci (VGS). This report completes 7 years of continuous surveillance data for telavancin using the approved reference method for in vitro testing methodology that includes the addition of polysorbate 80. For isolates collected from 2015 through 2017, telavancin exhibited potent activity against the following species and groups that have Clinical and Laboratory Standards Institute (CLSI)-approved interpretive criteria: MRSA (MIC90 value, 0.06 μg/mL; 100% susceptible), vancomycin-susceptible Enterococcus faecalis (MIC90 value, 0.25 μg/mL; 99.9% susceptible), BHS (MIC90 value, 0.03 μg/mL; 100% susceptible), and VGS (MIC90 value, 0.03 μg/mL; 99.0% susceptible). Importantly, telavancin maintained excellent antimicrobial activity against multidrug-resistant subsets of these pathogen groups and against ceftaroline-nonsusceptible (telavancin MIC90 value, 0.06 μg/mL; 100% susceptible) and ceftaroline-resistant (telavancin MIC90 value, 0.12 μg/mL; 100% susceptible) S. aureus isolates.
