The microdilution MICs of HMR 3647, erythromycin A, azithromycin, clarithromycin, roxithromycin, and pristinamycin against 50/90% of 249 Haemophilus influenzae and 50 Moraxella catarrhalis isolates were 2/4, 0.06/0.125; 8/16, 0.25/0.25; 2/4, 0.06/0.125; 16/16, 0.25/0.25; 32/>32, 1/2; and 2/4, 0.5/0.5 microg/ml. Azithromycin was bactericidal against all 10 H. influenzae and 3 of 5 M. catarrhalis isolates and HMR 3647, erythromycin A, clarithromycin, roxithromycin, and pristinamycin were bacteriostatic, against all 15 strains after 24 h at the MIC.
HMR 3647、红霉素A、阿奇霉素、克拉霉素、罗红霉素和 pristinamycin 对249株流感嗜血杆菌和50株卡他莫拉菌分离株中50/90%菌株的微量稀释法最低抑菌浓度(MIC)分别为2/4、0.06/0.125;8/16、0.25/0.25;2/4、0.06/0.125;16/16、0.25/0.25;32/>32、1/2;以及2/4、0.5/0.5微克/毫升。阿奇霉素对所有10株流感嗜血杆菌和5株卡他莫拉菌分离株中的3株具有杀菌作用,而HMR 3647、红霉素A、克拉霉素、罗红霉素和pristinamycin在MIC浓度下作用24小时后对所有15株菌株均具有抑菌作用。
