Sir,
Daptomycin is a novel cyclic lipopeptide antibiotic with a unique mechanism of action that involves disruption of multiple aspects of the plasma membrane function without penetration into the cytoplasm. This antibiotic exhibits rapid concentration-dependent killing and the occurrence of spontaneous resistant mutants is rare. Although several studies have shown good in vitro and in vivo activity of daptomycin against clinical isolates of enterococci,15
