RESUMEN
The coronavirus disease 2019 (COVID-19), which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread over the world, resulting in a global severe pneumonia pandemic. Both the cell receptor angiotensin-converting enzyme 2 (ACE2) and the breakdown of S protein by transmembrane serine protease 2 (TMPRSS2) are required by SARS-CoV-2 to enter the host cells. Similarly, the expression level of viral receptor genes in various organs determines the likelihood of viral infection. Several animal species have been found to be infected by the SARS-CoV-2, such as minks, posing an enormous threat to humans. Because the mice and rats were closely related to human and the fact that rats and mice have a risk of infection by SARS-CoV-2 with specific variants, we investigated the expression patterns of 79 receptor genes from 107 viruses, including SARS-CoV-2, in 14 organs of the rat and mouse, and 5 organs of the muskrat, to find the most likely host organs to become infected with certain viruses. The findings of this study are anticipated to aid in prevention of zoonotic infections spread by rats, mice, muskrats, and other rodents.
