”One of the earliest" SARS2 variant from a contaminated sample in Shanghai likely generated from cell lines or animal models frequently used at Wuhan SARS-CoV-2 experiments on Chinese hamster and lab monkey in 2019.” https://twitter.com/BP20185/status/1491368704856444930
Recently Csabai et al.1 have found a most likely contaminated metagenomic sample set from Antarctica that contained traces of unique SARS-CoV-2 variants. This is a short followup of that report where we attempt to find genetic footprint of the hosts. With reasonable confidence we could identify genetic material from mitochondria of Homo sapiens, green monkey and Chinese hamster. The latter two most probably originated from cell lines Vero E6 (or COS-7) and CHO respectively, which are frequent laboratory culture media for studying viruses including SARS-CoV-2 and its closest relatives. https://www.researchsquare.com/article/rs-1330800/v1
