The emergence of COVID-19 disease due to SARS-CoV-2 at the end of 2019 was rapidly associated with the isolation of the strain from co-culture onto VERO cells. These isolations quickly made it possible to carry out the first tests for antiviral agents’ susceptibility and drug repurposing. However, it seems important to make an inventory of all the cells that can support the growth of this virus and evaluate possible differences between isolates. In the present work, we tested 4 strains of SARS-CoV-2 locally isolated on a panel of 34 cell lines present in our laboratory and commonly used for the isolation of human pathogenic microorganism. After inoculation, cells were observed for cytopathic effects and quantitative real-time polymerase reaction was used to measure the virus replication on the cells. We were able to obtain growth on 7 cell lines, 6 simian, and the human Caco-2. The cytopathogenic effects are variable, ranging from lysis of the cell monolayer in 48–72 h to no cytopathic effect in spite of intense multiplication, as in Caco-2 cells. Interestingly, effect and multiplication varied widely according to the strain tested. In this paper, we explored the species specificity and tissue tropism of SARS-CoV-2 in vitro on a panel of cells available in our laboratory and identified human and animal cell lines susceptible to support SARS-CoV-2 replication. Our work highlights the importance of testing multiple strains when testing antiviral molecules and performing patho-physiological analyzes.
