In vitro activities of DX-619 and comparison quinolones against gram-positive cocci.
The in vitro activity of the novel quinolone DX-619 was compared to those of currently available quinolones against U.S. clinical isolates of Staphylococcus aureus, coagulase-negative staphylococci, Enterococcus spp., Streptococcus pyogenes, and Streptococcus pneumoniae. DX-619 was the most potent quinolone overall, indicating possible utility as an anti-gram-positive quinolone.
