Abstract

MICs of six extended-spectrum cephalosporins (cefotaxime, ceftriaxone, ceftazidime, FK 037, cefpirome, cefepime), three carbapenems (imipenem, meropenem, biapenem), and vancomycin for 49 penicillin-susceptible (S), 77 penicillin intermediate-resistant (I), and 51 penicillin-resistant (R) pneumococci were determined by agar dilution. Compared with ceftazidime (MICs for 90% of strains tested [MIC90s] of 2.0, 16.0, and 16.0 micrograms/ml for S, I, and R strains, respectively), all other cephalosporins yielded lower MICs (MIC90s of 0.06 to 0.125, 0.5 to 1.0, and 1.0 to 2.0 micrograms/ml against S, I, and R strains, respectively). All three carbapenems were very active, with MIC90s, even for R strains, of < or = 1.0 micrograms/ml. All strains were susceptible to vancomycin (MIC90 of 0.5 micrograms/ml).

摘要

采用琼脂稀释法测定了六种超广谱头孢菌素(头孢噻肟、头孢曲松、头孢他啶、FK 037、头孢匹罗、头孢吡肟)、三种碳青霉烯类抗生素(亚胺培南、美罗培南、比阿培南)和万古霉素对49株青霉素敏感(S)、77株青霉素中介耐药(I)和51株青霉素耐药(R)肺炎球菌的最低抑菌浓度(MIC)。与头孢他啶相比(S、I和R菌株的90%受试菌株的MIC[MIC90]分别为2.0、16.0和16.0微克/毫升),所有其他头孢菌素的MIC较低(对S、I和R菌株的MIC90分别为0.06至0.125、0.5至1.0和1.0至2.0微克/毫升)。所有三种碳青霉烯类抗生素都非常有效,即使对R菌株,MIC90也≤1.0微克/毫升。所有菌株对万古霉素敏感(MIC90为0.5微克/毫升)。
