Abstract Virus spillover remains a major challenge to public health. A panel of SARS-CoV-2-related coronaviruses have been identified in pangolins, while the infectivity and pathogenicity of these pangolin-origin coronaviruses (pCoV) in humans remain largely unknown. Herein, we comprehensively characterized the infectivity and pathogenicity of a recent pCoV isolate (pCoV-GD01) in human cells and human tracheal epithelium organoids and established animal models in comparison with SARS-CoV-2. pCoV-GD01 showed similar infectivity to SARS-CoV-2 in human cells and organoids. Remarkably, intranasal inoculation of pCoV-GD01 caused severe lung pathological damage in hACE2 mice and could transmit among cocaged hamsters. Interestingly, in vitro neutralization assays and animal heterologous challenge experiments demonstrated that preexisting immunity induced by SARS-CoV-2 infection or vaccination was sufficient to provide at least partial cross-protection against pCoV-GD01 challenge. Our results provide direct evidence supporting pCoV-GD01 as a potential human pathogen and highlight the potential spillover risk. |
