呼吸道病毒多病原检测技术研究进展

Development of Multi-Pathogen Detection Techniques for Respiratory Viruses

呼吸道病毒感染是导致人群发病和死亡的主要原因之一。通过多重病原检测迅速筛查大量致病原,已成为呼吸道病毒感染检测的重要技术。本文介绍了呼吸道病毒多病原检测技术及一些对呼吸道病毒检测有潜在应用价值的新兴技术。这些技术包括多重呼吸道病毒快速分离培养技术、传统多重逆转录PCR技术、多重实时定量PCR技术、微芯片技术、质谱技术及宏基因组技术等。这些技术的发展和应用,不但有助于提高呼吸道病毒感染的快速诊断和治疗,而且也将促进新型呼吸道病毒的发现。

Viral respiratory tract infection is among the leading causes of mortality and morbidity world-wide. Rapid screening methods for multiple detection of a wider range of pathogens become very important for diagnosis of respiratory infection. This article describes conventional detection technologies and several emerging multiplex assays that have pot-ential applications in the diagnosis and monitoring of respiratory viral infections. These techniques include new rapid culture system, multiplex reverse transcription-PCR, real-time reverse transcription PCR, solid and suspension microarrays, mass spectrometry as well as metagenomics methods. The development and application of these techniques will not only improve the ability of rapid detection and control of viral respiratory infection, but play pivotal roles in the rapid charac-terization of new viral pathogens.
