We reformulated a multiplex PCR algorithm for serotyping of pneumococcal meningitis directly on cerebrospinal fluid (CSF). Compared to established methods on isolates, CSF-based PCR had at least 80% sensitivity and 100% specificity. In regional meningitis surveillance, CSF-based PCR increased the serotype information yield from 40% of cases (isolate testing) to 90%.
我们重新设计了一种用于直接从脑脊液 (CSF) 中对肺炎球菌性脑膜炎进行血清分型的多重 PCR 算法。与分离株的既定方法相比,基于 CSF 的 PCR 具有至少 80%的灵敏度和 100%的特异性。在区域性脑膜炎监测中,基于 CSF 的 PCR 将血清型信息的检出率从 40%(分离物检测)提高到 90%。
