Not sure if I'm reading this correctly or not can someone else take a look and let me know. From what I'm reading they tested the sars cov 2 virus with a brown bats dna and found that it was not replicating during testing. So if it wasn't replicating during testing and it wasn't susceptible to the virus it couldn't have come from a bat like everyone keeps claiming??? here is the excerpt the entire article link in bottom for viewing pleasure.
Because research has been initiated to study and respond to SARS-CoV-2, information about cell lines and types susceptible to infection is needed. Therefore, we examined the capacity of SARS-CoV-2 to infect and replicate in several common primate and human cell lines, including human adenocarcinoma cells (A549), human liver cells (HUH7.0), and human embryonic kidney cells (HEK-293T), in addition to Vero E6 and Vero CCL81 cells. We also examined an available big brown bat kidney cell line (EFK3B) for SARS-CoV-2 replication capacity. Each cell line was inoculated at high multiplicity of infection and examined 24 h postinfection (Figure 3, panel A). No CPE was observed in any of the cell lines except in Vero cells, which grew to >107 PFU at 24 h postinfection. In contrast, HUH7.0 and 293T cells showed only modest viral replication, and A549 cells were incompatible with SARS-CoV-2 infection.
