In vitro activity of LY146032 (daptomycin) against selected aerobic bacteria

Abstract

The in vitro activity of the new lipopeptide antibiotic LY146032 was generally four-fold greater (MIC 90 less than or equal to 0.5 microgram/ml) than that of vancomycin against methicillin-susceptible or methicillin-resistant Staphylococcus aureus and coagulase-negative species of Staphylococcus. Enterococci, Streptococcus bovis, group B and viridans streptococci, and Corynebacterium group J-K isolates were inhibited by less than or equal to 4 micrograms/ml of LY146032, which represented activity equivalent to or greater than that of vancomycin. Unlike vancomycin, LY146032 was bactericidal for Enterococcus faecalis, Enterococcus faecium and Listeria monocytogenes. Due to its bactericidal properties LY146032 appeared to represent an improvement over vancomycin and teicoplanin.
