We compared StrepB Select medium (Select) after enrichment with conventional culture for the detection of Group B Streptococcus (GBS). Postenrichment sensitivities of Select and conventional culture were 98.8% and 92.2%, respectively (P<0.05). Select was superior for detection of GBS from vaginal-rectal specimens. Growth of non-GBS colonies required additional work to exclude the presence of GBS, especially after 48 h of incubation. Incubation of Select beyond 24 h did not significantly increase the yield of GBS.
我们比较了在常规培养后使用 StrepB Select 培养基(Select)对 B 组链球菌(GBS)的检测效果。与常规培养相比,Select 对 GBS 的后置增菌灵敏度分别为 98.8%和 92.2%(P<0.05)。Select 更有利于从阴道直肠标本中检测 GBS。非 GBS 菌落的生长需要进一步的工作来排除 GBS 的存在,尤其是在孵育 48 小时后。Select 的孵育时间超过 24 小时不会显著增加 GBS 的产量。
