Abstract
This study used real-time PCR assays to screen small sample volumes for a comprehensive range of 35 respiratory pathogens. Initial thermocycling was limited to 20 cycles to avoid competition for reagents, followed by a secondary real-time multiplex PCR. Supplementary semi-nested human metapneumovirus and picornavirus PCR assays were required to complete the acute respiratory pathogen profile. Potential pathogens were detected in 85 (70%) of pernasal aspirates collected from 121 children with acute respiratory symptoms. Multiple pathogens were detected in 29 (24%) of those samples. The tandem multiplex real-time PCR was an efficient method for the rapid detection of multiple pathogens.
摘要
本研究使用实时 PCR 检测法对小样本量进行了全面的 35 种呼吸道病原体筛查。初始热循环限制在 20 个循环，以避免试剂竞争，随后进行二次实时多重 PCR。需要补充半巢式人类偏肺病毒和小核糖核酸病毒 PCR 检测法来完成急性呼吸道病原体分析。在 121 例急性呼吸道症状儿童的鼻抽吸物中，有 85 例（70%）检测到潜在病原体。在这些样本中，有 29 例（24%）检测到多种病原体。串联多重实时 PCR 是一种快速检测多种病原体的有效方法。
