Activity of DX-619 compared to other agents against viridans group streptococci, Streptococcus bovis, and Cardiobacterium hominis.

ABSTRACT: Against 198 viridans group streptococci, 25 Streptococcus bovis strains, and 5 Cardiobacterium hominis strains, MICs of DX-619, a des-F(6)-quinolone, were between 0.004 and 0.25 microg/ml. These MICs were lower than those of other quinolones (< or = 0.008 to > 32 microg/ml). Beta-lactam MICs were between < or = 0.008 and 16 microg/ml. Azithromycin resistance was found in most species, while most were telithromycin susceptible. Glycopeptides and linezolid were active against viridans group strains but inactive against C. hominis.
