Abstract

This study compared daptomycin (LY146032) with penicillin G procaine and vancomycin without and with gentamicin for treatment of experimental enterococcal endocarditis. The strain of Streptococcus (Enterococcus) faecalis used in this study was killed by daptomycin in vitro in broth but not in serum. In rabbits treated for 3 days, daptomycin significantly reduced bacterial counts of vegetations compared with no therapy but was significantly less effective than penicillin G procaine or vancomycin. Daptomycin-gentamicin significantly reduced bacterial counts of vegetations compared with daptomycin alone but was significantly less effective than vancomycin plus gentamicin. The efficacy of daptomycin-gentamicin did not differ significantly from that of penicillin G procaine-gentamicin. The lack of enterococcal killing by daptomycin alone in serum and in experimental endocarditis is probably related to the high protein binding of the agent.
