近日，央視新聞頻道播出“果子貍含冤10年蝙蝠才是非典病毒(virus)元兇” 新聞，消息稱，非典病毒的天然宿主(parasitifer)是一種名叫“中華菊花蝠”的蝙蝠，當(dāng)初果子貍被冤枉了。其實美國《科學(xué)》雜志(2005.9)就有相關(guān)報道，下面提供此報道的雙語文章，與同等學(xué)力英語考生分享：

　　Bats Are Natural Reservoirs of SARS-Like Coronaviruses

　　蝙蝠是類非典冠狀病毒的天然宿主

　　Severe acute respiratory syndrome (SARS) emerged in 2002 to 2003 in southern China. The origin of its etiological agent, the SARS coronavirus (SARS-CoV), remains elusive. Here we report that species of bats are a natural host of coronaviruses closely related to those responsible for the SARS outbreak.

　　在2002到2003年間，非典(SARS)在中國南方爆發(fā)。非典病原體——非典冠狀病毒的來源還未找到。我們在此公布，蝙蝠物種是冠狀病毒的天然宿主，并與非典疫情的爆發(fā)脫不開干系。

　　These viruses, termed SARS-like coronaviruses (SL-CoVs), display greater genetic variation than SARS-CoV isolated from humans or from civets. The human and civet isolates of SARS-CoV nestle phylogenetically within the spectrum of SL-CoVs, indicating that the virus responsible for the SARS outbreak was a member of this coronavirus group.

　　在醫(yī)學(xué)上，這些病毒被稱作類非典冠狀病毒，和從人類或果子貍身上提取的非典冠狀病毒相比，它們具有更強的遺傳變異性。人體和果子貍身上分離出的非典冠狀病毒可以與類非典冠狀病毒群體共存，這表明，引起非典疫情的病毒是一種冠狀病毒。
