研究表明SARS病毒是变异的冠状病毒(SARS CoV) ,其毒力远远强于其他已知的家族成员,病毒学诊断对SARS的确诊具有决定性意义[1] 。SARS CoV基因测序的完成为该病毒的扩增引物的设计提供了条件,也对SARS的诊断及药物研究具有重要意义。来源于患者的标本具有足够的基因信息,对它进 Studies have shown that the SARS virus is a variant of the coronavirus (SARS CoV), its virulence is much stronger than other known family members, virological diagnosis of SARS is of decisive significance [1]. Completion of SARS CoV gene sequencing provides conditions for the design of the amplification primers of the virus and is also of great significance for the diagnosis of SARS and drug research. Specimens from patients have enough genetic information to enter it
