  • Title: [Bactericidal effect of daptomycin (LY 146032) compared with vancomycine and teicoplanin against gram-positive bacteria].

    Abstract:
    Daptomycin (LY 146032) is a semi-synthetic antibiotic whose structure consists of a cyclic peptide with a lipophilic chain. It inhibits synthesis of the bacterial wall differently than vancomycin and teicoplanin. The bactericidal activity of daptomycin was compared with that of vancomycin and of teicoplanin with regard to 54 Gram positive strains of bacteria: (S. aureus meti S and meti R; S. epidermidis meti S and meti R; E. faecalis, E. faecium, and Corynebacterium group JK). Vancomycin and teicoplanin have the same slow and time-dependent bactericidal activity. The activity of daptomycin is different: rapid and concentration-dependent, similar to that of the aminoglycosides. In the case of the Corynebacteria, however, the activity of daptomycin is comparable to that of vancomycin and of teicoplanin slow and time-dependent.
