A total of 1,991 group B streptococcus (GBS) isolates, collected in 2008 and 2009, were tested for non-penicillin susceptibility by broth microdilution, disk testing, and oxacillin screening agar. No GBS isolates were non-penicillin susceptible. Oxacillin and ceftizoxime disk testing results showed that proposed screening criteria are nonspecific. The oxacillin screening agar was specific but of unknown sensitivity.
共检测了 1991 株 2008 年和 2009 年分离的 B 群链球菌(GBS),采用肉汤微量稀释法、纸片扩散法和苯唑西林筛选琼脂进行非青霉素类药物敏感性检测。没有非青霉素类药物敏感的 GBS 分离株。苯唑西林和头孢噻肟纸片扩散法检测结果表明,所提出的筛选标准是非特异性的。苯唑西林筛选琼脂具有特异性,但敏感性未知。
