The activity of cephradine and the influence of pH on its activity against 70 Gardnerella vaginalis strains were determined. Serial dilutions of cephradine (0.062 to 256 micrograms/ml) were incorporated into Dunkelberg agar, inoculated with a Steers replicator, incubated in 5% CO2 for 48 h, and examined. The minimal inhibitory concentrations for 90% of the isolates were 16 and 8.0 micrograms/ml at pH 7.0 to 6.0 and 5.5, respectively.
测定了头孢拉定的活性及其pH值对其抗70株阴道加德纳菌活性的影响。将头孢拉定的系列稀释液(0.062至256微克/毫升)加入邓克尔伯格琼脂中,用施泰尔斯复制器接种,在5%二氧化碳中孵育48小时,然后进行检查。在pH值为7.0至6.0和5.5时,90%分离株的最低抑菌浓度分别为16和8.0微克/毫升。
