Novel coronavirus (SARS-CoV-2) is found to cause a large outbreak started from Wuhan since December 2019 in China and SARS-CoV-2 infections have been reported with epidemiological linkage to China in 25 countries until now. We isolated SARS-CoV-2 from the oropharyngeal sample obtained from the patient with the first laboratory-confirmed SARS-CoV-2 infection in Korea. Cytopathic effects of SARS-CoV-2 in the Vero cell cultures were confluent 3 days after the first blind passage of the sample. Coronavirus was confirmed with spherical particle having a fringe reminiscent of crown on transmission electron microscopy. Phylogenetic analyses of whole genome sequences showed that it clustered with other SARS-CoV-2 reported from Wuhan.
新型冠状病毒(SARS-CoV-2)被发现是导致自 2019 年 12 月以来在中国武汉爆发的大规模疫情的罪魁祸首,截至目前,已有 25 个国家报告了与中国有流行病学关联的 SARS-CoV-2 感染病例。我们从韩国首例实验室确诊的 SARS-CoV-2 感染患者的咽拭子样本中分离出了 SARS-CoV-2。该样本首次盲传 3 天后,在 Vero 细胞培养物中出现了明显的细胞病变效应。电镜观察发现,该病毒呈具有冠状边缘的球形颗粒。全基因组序列的系统进化分析表明,它与武汉报告的其他 SARS-CoV-2 聚为一簇。
