The comparative in-vitro activity of HMR 3647, a new ketolide antibiotic,
was investigated against 492 clinical isolates of gram- positive bacteria,
including multiply resistant strains, by an agar- dilution technique. All
streptococci tested were inhibited by the new ketolide at concentrations
< or = 0.5 mg/L. HMR 3647 was more potent than erythromycin against
staphylococci. For enterococci the new compound yielded an MIC90 of 8 mg/L.
Erysipelothrix spp., Pediococcus spp., Leuconostoc spp., Lactobacillus
spp., JK diphtheroids and Listeria monocytogenes were also susceptible to
the new ketolide.
