Agar dilution was used to test the activities of HMR 3647, erythromycin A, azithromycin, clarithromycin, roxithromycin, clindamycin, and quinupristin-dalfopristin against 235 strains of Enterococcus faecalis. HMR 3647 was the most active compound (MICs at which 50 and 90% of the isolates are inhibited [MIC50 and MIC90, respectively] of 0.06 and 4.0 microg/ml, respectively). The MIC50 and MIC90 (with the MIC50 given first and the MIC90 given second; both in micrograms per milliliter) for other compounds were as follows: 4.0 and >32.0 for erythromycin A, 16.0 and >32.0 for azithromycin, 2.0 and >32 for clarithromycin, 32.0 and >32.0 for roxithromycin, 32.0 and >32.0 for clindamycin, and 8.0 and 16.0 for quinupristin-dalfopristin. All compounds were only bacteriostatic.
采用琼脂稀释法检测HMR 3647、红霉素A、阿奇霉素、克拉霉素、罗红霉素、克林霉素和奎奴普丁-达福普汀对235株粪肠球菌的活性。HMR 3647是活性最强的化合物(分别抑制50%和90%分离株的最低抑菌浓度[分别为MIC50和MIC90]分别为0.06和4.0微克/毫升)。其他化合物的MIC50和MIC90(先给出MIC50,后给出MIC90;单位均为微克/毫升)如下:红霉素A为4.0和>32.0,阿奇霉素为16.0和>32.0,克拉霉素为2.0和>32,罗红霉素为32.0和>32.0,克林霉素为32.0和>32.0,奎奴普丁-达福普汀为8.0和16.0。所有化合物均仅具有抑菌作用。
