Abstract

This paper reports on the development of a one-step, real-time reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay targeting the hemagglutinin (HA) gene for the rapid molecular-based detection of pandemic (H1N1) 2009 virus. The detection limit of the pandemic (H1N1) 2009 virus HA-specific RT-LAMP assay was same as that of the currently used real-time reverse transcription-PCR method. The assay detected the pandemic (H1N1) 2009 virus HA gene in 136 RNA samples extracted from nasopharyngeal swab specimens from Japanese and Vietnamese patients. No cross-reactive amplification with the RNA of other seasonal influenza viruses was observed, and the detection of specific viral genome targets in clinical specimens was achieved in less than 40 min. The sensitivity and specificity of the pandemic (H1N1) 2009 virus HA-specific RT-LAMP assay obtained in this study were 97.8% and 100%, respectively. Use of the (H1N1) 2009 virus HA-specific RT-LAMP assay will enable the faster and easier diagnosis of pandemic (H1N1) 2009 virus infection, especially in resource-limited situations in developing countries.

摘要

本文报道了一种针对血凝素 (HA) 基因的一步法、实时逆转录环介导等温扩增 (RT-LAMP) 检测方法的开发,用于快速基于分子的检测大流行 (H1N1) 2009 病毒。大流行 (H1N1) 2009 病毒 HA 特异性 RT-LAMP 检测方法的检测限与目前使用的实时逆转录-PCR 方法相同。该检测方法在从日本和越南患者鼻咽拭子样本中提取的 136 个 RNA 样本中检测到大流行 (H1N1) 2009 病毒 HA 基因。未观察到与其他季节性流感病毒的 RNA 发生交叉反应性扩增,在不到 40 分钟的时间内即可在临床标本中检测到特定病毒基因组靶标。本研究中获得的大流行 (H1N1) 2009 病毒 HA 特异性 RT-LAMP 检测方法的灵敏度和特异性分别为 97.8%和 100%。使用 (H1N1) 2009 病毒 HA 特异性 RT-LAMP 检测方法将能够更快、更容易地诊断大流行 (H1N1) 2009 病毒感染,特别是在发展中国家资源有限的情况下。
