有关导致持续COVID-19大流行的冠状病毒的起源和宿主的知识仍然不完整。迄今为止,在中国云南省的菊头蝠样本中检测到了与SARS-CoV-2最接近的亲属。在这里,我们描述了2010年在柬埔寨采样的两只沙氏菊头蝠中SARS-CoV-2相关冠状病毒的鉴定。宏基因组测序鉴定出与SARS-CoV-2具有92.6%核苷酸同一性的几乎相同的病毒。大多数基因组区域与SARS-CoV-2密切相关,除了刺突区域,该区域与人类ACE 2介导的进入不相容。在中国没有发现的蝙蝠物种中发现这些病毒表明SARS-CoV-2相关病毒的地理分布比以前报道的要广泛得多,并表明东南亚是未来冠状病毒监测的关键地区。在这项研究中,Delaune等人,从柬埔寨两个蝙蝠样本中分离并鉴定SARS-CoV-2相关冠状病毒。他们的研究结果表明,SARS-CoV-2相关病毒的地理分布比以前报道的更广泛。
Knowledge of the origin and reservoir of the coronavirus responsible for the ongoing COVID-19 pandemic is still fragmentary. To date, the closest relatives to SARS-CoV-2 have been detected in Rhinolophus bats sampled in the Yunnan province, China. Here we describe the identification of SARS-CoV-2 related coronaviruses in two Rhinolophus shameli bats sampled in Cambodia in 2010. Metagenomic sequencing identifies nearly identical viruses sharing 92.6% nucleotide identity with SARS-CoV-2. Most genomic regions are closely related to SARS-CoV-2, with the exception of a region of the spike, which is not compatible with human ACE2-mediated entry. The discovery of these viruses in a bat species not found in China indicates that SARS-CoV-2 related viruses have a much wider geographic distribution than previously reported, and suggests that Southeast Asia represents a key area to consider for future surveillance for coronaviruses. In this study, Delaune et al., isolate and characterise a SARS-CoV-2-related coronavirus from two bats sampled in Cambodia. Their findings suggest that the geographic distribution of SARS-CoV-2-related viruses is wider than previously reported.
