已知存在三种人类冠状病毒:人类冠状病毒 229E (HCoV-229E)、HCoV-OC43 和严重急性呼吸综合征 (SARS) 相关冠状病毒 (SARS-CoV)。在这里,我们报告了使用一种新的病毒发现方法对第四种人类冠状病毒 HCoV-NL63 的鉴定。该病毒是从一名患有细支气管炎和结膜炎的 7 个月大的儿童身上分离出来的。完整的基因组序列表明,这种病毒不是重组病毒,而是一种新的1组冠状病毒。 HCoV-NL63 的体外宿主细胞范围值得注意,因为它在三级猴肾细胞和猴肾 LLC-MK2 细胞系上复制。病毒基因组具有独特的特征,包括刺突蛋白内独特的 N 末端片段。对患有呼吸道疾病的个体的临床标本进行筛查,发现另外 7 名 HCoV-NL63 感染者,表明该病毒在人群中广泛传播。本文的在线版本 (doi:10.1038/nm1024) 包含补充材料,可供授权用户使用。
Three human coronaviruses are known to exist: human coronavirus 229E (HCoV-229E), HCoV-OC43 and severe acute respiratory syndrome (SARS)-associated coronavirus (SARS-CoV). Here we report the identification of a fourth human coronavirus, HCoV-NL63, using a new method of virus discovery. The virus was isolated from a 7-month-old child suffering from bronchiolitis and conjunctivitis. The complete genome sequence indicates that this virus is not a recombinant, but rather a new group 1 coronavirus. The in vitro host cell range of HCoV-NL63 is notable because it replicates on tertiary monkey kidney cells and the monkey kidney LLC-MK2 cell line. The viral genome contains distinctive features, including a unique N-terminal fragment within the spike protein. Screening of clinical specimens from individuals suffering from respiratory illness identified seven additional HCoV-NL63-infected individuals, indicating that the virus was widely spread within the human population.
