摘 要: SARS冠状病毒(SARS—CoV)是一种新现病毒,可感染多种动物,果子狸是人类SARS—CoV重要的动物宿主之一,是已知较理想的实验动物模型。遗传因素在SARS-CoV的出现过程中起重要作用,它很可能是哺乳动物和鸟类冠状病毒之间重组产生的新物种,但发生基因重组不是SARS在人群中暴发的原因。 SARS corunavirus is an emerging virus. A lot of animals could be infected by SARS-CoV and Himalayan palm civets, as one of important hosts, is an ideal animal model. Viral genetic factors have been implicated in the emergence of SARS-CoV, with the suggestion that this virus is a recombinant between mammalian and avian coronaviruses. However, the recombination is unlikely to explain the appearance of SARS in humans.
