Abstract
Vaginal group B streptococcus (GBS) and Escherichia coli isolates were tested for their susceptibilities to ampicillin. All 414 GBS isolates tested were susceptible to ampicillin; the MIC at which 90% of the isolates were inhibited (MIC90) was 0.125 microg/ml, and the range was 0.06 to 0.25 microg/ml. The MIC50 for the 342 E. coli isolates tested was 4.0 microg/ml, and 27% were resistant to ampicillin.

对阴道B族链球菌（GBS）和大肠杆菌分离株进行了氨苄西林敏感性测试。所测试的414株GBS分离株均对氨苄西林敏感；90%的分离株被抑制时的最低抑菌浓度（MIC90）为0.125微克/毫升，范围为0.06至0.25微克/毫升。所测试的342株大肠杆菌分离株的MIC50为4.0微克/毫升，27%对氨苄西林耐药。
