The
activity of tigecycline against Staphylococcus epidermidis
growing in an in vitro adherent-cell biofilm model was determined.
Tigecycline minimum bactericidal concentrations (MBCs) ranged from 1 to
8 µg/ml for S. epidermidis growing in a biofilm of
adherent cells, compared to MBCs of 0.12 to >32 µg/ml
for freely growing cells. The killing activity of tigecycline against
the adherent bacteria was at least fourfold better than that of
vancomycin and
daptomycin.
