We investigated a possible synergistic effect of a macrolide and beta-lactams against Streptococcus pneumoniae strains with different resistance profiles. Checkerboard and time-kill assays of erythromycin combined with penicillin or cefotaxime essentially showed indifference, suggesting that these antibiotics in combinations in vitro act substantially as individuals in their activity against S. pneumoniae.
我们研究了大环内酯类药物与β-内酰胺类药物对不同耐药谱的肺炎链球菌菌株可能存在的协同作用。红霉素与青霉素或头孢噻肟的棋盘法和杀菌动力学试验结果基本显示无协同作用,这表明这些抗生素联合使用时,在体外对肺炎链球菌的活性基本上与单独使用时相同。
