严重急性呼吸综合征冠状病毒2(SARS-CoV-2)最近出现,导致人类广泛感染。沙特阿拉伯王国报告了SARS-CoV-2感染,中东呼吸综合征冠状病毒(MERS-CoV)引起季节性爆发,病死率约为37%。 在这里,我们表明,有一个理论上的可能性,未来的重组事件之间的SARS-CoV-2和MERS-CoV RNA。通过计算分析,我们已经确定了ORF 1ab和S基因内的同源基因组区域,可以促进重组,并分别分析了SARS-CoV-2和MERS-CoV,ACE 2和DPP 4的细胞受体的共表达模式,以确定可能促进共感染的人体解剖部位。此外,我们通过比较已知的病毒刺突蛋白-受体相互作用残基,研究了各种动物物种对MERS-CoV和SARS-CoV-2感染的可能易感性。总之,我们认为SARS-CoV-2和MERS-CoV RNA之间的重组是可能的,并敦促高风险地区的公共卫生实验室开发诊断能力,用于检测患者样本中的重组冠状病毒。
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recently emerged to cause widespread infections in humans. SARS-CoV-2 infections have been reported in the Kingdom of Saudi Arabia, where Middle East respiratory syndrome coronavirus (MERS-CoV) causes seasonal outbreaks with a case fatality rate of ~37 %. Here we show that there exists a theoretical possibility of future recombination events between SARS-CoV-2 and MERS-CoV RNA. Through computational analyses, we have identified homologous genomic regions within the ORF1ab and S genes that could facilitate recombination, and have analysed co-expression patterns of the cellular receptors for SARS-CoV-2 and MERS-CoV, ACE2 and DPP4, respectively, to identify human anatomical sites that could facilitate co-infection. Furthermore, we have investigated the likely susceptibility of various animal species to MERS-CoV and SARS-CoV-2 infection by comparing known virus spike protein–receptor interacting residues. In conclusion, we suggest that a recombination between SARS-CoV-2 and MERS-CoV RNA is possible and urge public health laboratories in high-risk areas to develop diagnostic capability for the detection of recombined coronaviruses in patient samples.
