evaluate severe acute respiratory syndrome coronavirus 2 infectivity by pseudoviral particles.since the outbreak of severe acute respiratory syndrome coronavirus 2 (sars-cov-2) infection in humans in late 2019, it has rapidly spread worldwide. to identify the biological characteristics of sars-cov-2 in a normal laboratory environment (biosafety level 2 [bsl-2]), a lentiviral-based nucleocapsid was used to carry the spike protein of sars-cov-2 onto the surface of pseudoviral particles as a surrogate model to evaluate the infective characterization of sars-cov-2. this study indicated that ...202032275081
susceptibility of tree shrew to sars-cov-2 infection.since severe acute respiratory syndrome coronavirus 2 (sars-cov-2) became a pandemic event in the world, it has not only caused huge economic losses, but also a serious threat to global public health. many scientific questions about sars-cov-2 and coronavirus disease (covid-19) were raised and urgently need to be answered, including the susceptibility of animals to sars-cov-2 infection. here we tested whether tree shrew, an emerging experimental animal domesticated from wild animal, is susceptib ...202032994418
