Popis: Emerging infectious diseases have caused a global effort for development of fast and accurate detection techniques. The rapidly mutating nature of viruses presents a major difficulty, highlighting the need for specific detection of genetically diverse strains. One such infectious agent is SARS-associated coronavirus (SARS-CoV), which emerged in 2003. This study aimed to develop a real-time RT-PCR detection assay specific for SARS-CoV, taking into account its intrinsic polymorphic nature due to genetic drift and recombination and the possibility of continuous and multiple introductions of genetically non-identical strains into the human population, by using mismatch-tolerant molecular beacons designed to specifically detect the SARS-CoV S, E, M and N genes. These were applied in simple, reproducible duplex and multiplex real-time PCR assays on 25 post-mortem samples and constructed RNA controls, and they demonstrated high target detection ability and specificity. This assay can readily be adapted for detection of other emerging and rapidly mutating pathogens. © 2011 Springer-Verlag. 156 671 680 Cited By :5
