【摘要】：目的通过比较普通培养法、先增菌再培养法和显色平板法,得到适合实验室快速检测B群链球菌的方法。方法分别用普通培养法、先增菌再培养法和显色平板法对1 526例围产期孕妇进行B群链球菌检测,并进行比较。结果普通培养法、先增菌再培养法、显色平板法的阳性率分别为8.1%、9.2%、9.4%,差异无统计学意义(P0.05)。结论显色平板法检测B群链球菌具有较高的灵敏度和特异性,可以直接接种标本,操作简便,阳性率不低于先增菌再培养法,适合各级医疗机构用于围产期GBS筛查。
[Abstract]:Objective to compare the common culture method, the first culture method and the chromogenic plate method, and to obtain a method suitable for rapid detection of group B streptococcus in laboratory. Group B streptococcus of 1 526 pregnant women during perinatal period were detected by first culture method and chromogenic plate method, and compared. Results the common culture method, the first culture method and the second culture method were used to detect group B streptococcus in perinatal period. The positive rates of chromogenic plate method were 8.1and 9.29.4respectively, and there was no significant difference between them (P 0.05). Conclusion the method of chromogenic plate has high sensitivity and specificity for detecting group B streptococcus, and can be directly inoculated with specimens. The positive rate is not lower than that of the method of first increasing bacteria and then culture. Suitable for perinatal GBS screening in medical institutions at all levels.
