In vitro activity of an oral streptogramin antimicrobial, XRP2868, against gram-positive bacteria.
The comparative in vitro potency of XRP2868, a new oral semisynthetic streptogramin antibiotic, was evaluated against gram-positive bacteria. XRP2868 inhibited all staphylococci at < or = 1 microg/ml and all non-pneumococcal streptococci at < or = 0.25 microg/ml and was fourfold more potent than quinupristin-dalfopristin against Staphylococcus aureus and Enterococcus faecium.
