Abstract

The activities of azithromycin, erythromycin, and ciprofloxacin against 21 Legionella isolates were measured by an agar dilution method and in macrophages. The MICs for 90% of strains tested were 2.0, 1.0, and 0.5 micrograms/ml for azithromycin, erythromycin, and ciprofloxacin, respectively. Azithromycin and ciprofloxacin were both bactericidal in the macrophage system, but erythromycin was bacteriostatic.

摘要

采用琼脂稀释法并在巨噬细胞中测定了阿奇霉素、红霉素和环丙沙星对21株嗜肺军团菌分离株的活性。阿奇霉素、红霉素和环丙沙星对90%受试菌株的最低抑菌浓度(MIC)分别为2.0、1.0和0.5微克/毫升。在巨噬细胞系统中,阿奇霉素和环丙沙星均具有杀菌作用,但红霉素具有抑菌作用。
