The in vitro susceptibilities of 49 strains of Chlamydia trachomatis and 3 strains of Chlamydia pneumoniae to azithromycin and tetracycline or doxycycline were determined. The MIC of azithromycin ranged from < or = 0.06 to 1.0 micrograms/ml, the MIC of tetracycline ranged from 0.03 to 0.12 micrograms/ml, and the MIC of doxycycline ranged from 0.015 to 0.06 micrograms/ml against C. trachomatis. The MIC ranges for C. pneumoniae were 0.12 to 0.25 micrograms/ml for azithromycin and 0.06 to 0.12 micrograms/ml for tetracycline. All minimal chlamydicidal concentrations were either equal to the MIC or one or two dilutions higher. No strains resistant to these antibiotics were detected. In vitro activity shows that azithromycin is highly active against C. trachomatis and C. pneumoniae.
测定了49株沙眼衣原体和3株肺炎衣原体对阿奇霉素、四环素或多西环素的体外敏感性。针对沙眼衣原体,阿奇霉素的最低抑菌浓度(MIC)范围为≤0.06至1.0微克/毫升,四环素的MIC范围为0.03至0.12微克/毫升,多西环素的MIC范围为0.015至0.06微克/毫升。针对肺炎衣原体,阿奇霉素的MIC范围为0.12至0.25微克/毫升,四环素的MIC范围为0.06至0.12微克/毫升。所有最小杀衣原体浓度均等于MIC或比MIC高1倍或2倍稀释度。未检测到对这些抗生素耐药的菌株。体外活性表明,阿奇霉素对沙眼衣原体和肺炎衣原体具有高度活性。
