摘要
The in vitro activities of ABT-773, azithromycin, erythromycin, and clindamycin were compared by testing 1,223 clinical isolates selected to represent different species and phenotypes. ABT-773 was particularly potent against staphylococci (the MIC at which 90% of the strains tested were inhibited [MIC90] was less than or equal to0.06 mug/ml), including all strains that were macrolide resistant but clindamycin susceptible. Streptococcus pneumoniae and other streptococci were inhibited by low concentrations of ABT-773, and that included most erythromycin-resistant strains. Against Haemophilus influenzae, ABT-773 and azithromycin were similar in their antibacterial potency (MIC90, 4.0 and 2.0 mug/ml, respectively).
