Microdilution MIC testing was used to test the susceptibility of 202 pneumococci to LY 333328 and six other agents. LY 333328 was the most active glycopeptide (MIC at which 90% of the pneumococci were inhibited [MIC90], 0.008 microgram/ml), followed by teicoplanin (MIC90, 0.06 microgram/ml) and vancomycin (MIC90, 0.5 microgram/ml). Rifampin resistance was seen in some penicillin-resistant strains. The MICs of imipenem and ceftriaxone rose with those of penicillin. Time-kill testing confirmed the excellent antipneumococcal activity of LY 333328.
采用微量稀释法进行最低抑菌浓度(MIC)检测,以测试202株肺炎球菌对LY 333328及其他六种药物的敏感性。LY 333328是活性最强的糖肽类药物(90%肺炎球菌被抑制时的MIC[MIC90]为0.008微克/毫升),其次是替考拉宁(MIC90为0.06微克/毫升)和万古霉素(MIC90为0.5微克/毫升)。在一些耐青霉素菌株中发现了对利福平的耐药性。亚胺培南和头孢曲松的MIC随青霉素的MIC升高而升高。时间杀菌试验证实了LY 333328具有出色的抗肺炎球菌活性。
