Abstract

A multiplex PCR assay was developed to screen blood cultures from children in The Gambia with suspected pneumonia for the simultaneous detection of Haemophilus influenzae type b and Streptococcus pneumoniae isolates. Analysis of 295 blood cultures showed that PCR detected the organisms in all samples positive by culture in two samples infected with H. influenzae type b and four samples infected with S. pneumoniae that were culture negative, indicating that this method is sensitive for detecting these organisms in blood cultures.

摘要

开发了一种多重PCR检测方法,用于筛查冈比亚疑似肺炎儿童的血培养物,以同时检测b型流感嗜血杆菌和肺炎链球菌分离株。对295份血培养物的分析表明,PCR在2份感染b型流感嗜血杆菌且培养阴性的样本以及4份感染肺炎链球菌且培养阴性的样本中,检测到了所有培养阳性样本中的病原体,这表明该方法在血培养物中检测这些病原体具有敏感性。
