Title: Development of a real-time RT-PCR assay for a novel influenza A (H1N1) virus. Author: Jiang T, Kang X, Deng Y, Zhao H, Li X, Yu X, Yu M, Qin E, Zhu Q, Yang Y, Qin C. Journal: J Virol Methods; 2010 Feb; 163(2):470-3. PubMed ID: 19815030. Abstract: A pandemic caused by a novel influenza A virus (H1N1) poses a serious public health threat. In this study, a real-time reverse transcriptase PCR (RT-PCR) assay based on the hemagglutinin gene was developed that discriminates the novel H1N1 from swine influenza virus, seasonal H1N1/H3N2 virus and the highly pathogenic H5N1 avian influenza virus. The sensitivity of this assay was 0.2 50% tissue culture infective dose of virus and 200 copies of in vitro-transcribed target RNA. Three hundred and forty-eight clinical specimens from suspected H1N1 patients were tested using this assay, and forty-two (12.07%) were found to be positive. Tests using the real-time PCR assay recommended by WHO and virus isolation gave identical results. This sensitive and specific real-time RT-PCR assay will contribute to the early diagnosis and control of the emerging H1N1 influenza pandemic.[Abstract] [Full Text] [Related] [New Search]
