Against 210 Haemophilus influenzae strains (39.0% beta-lactamase positive), microbroth dilution tests sho that azithromycin ( Zithromax ) and ABT-773 had the lowest MICs (0.5 to 4.0 and 1.0 to 8.0 microg/ml, respectively), follo by clarithromycin and roxithromycin (4.0 to >32.0 list of antibiotics antibiotics microg/ml). Of the beta-lactams, ceftriaxone had the lowest MICs (8.0 h), follo by clarithromycin, erythromycin, antibiotics and roxithromycin. Susceptibilities of Haemophilus influenzae and Moraxella catarrhalis to ABT-773 compared to their susceptibilities to 11 other agents.The activity of the ketolide ABT-773 against Haemophilus and Moraxella was compared to those of 11 other agents. Beta-Lactam PAEs were similar and shorter than those of the ketolide-macrolide-azalide group for all strains tested..
