Alpha, Delta, both have less VERO E6 than Wuhan/D614G. Omicron, also. It is also the least VERO-growing lineage. http://virologyj.biomedcentral.com/articles/10.1186/s12985-022-01802-5 http://www.nature.com/articles/s41586-021-04266-9 http://www.sciencedirect.com/science/article/pii/S2589004221015595 This is NOT something you expect from a wildlife virus. They shouldn’t be adapted best to lab cell lines right out of the box. All adaptation trajectories (both from live mice, humans and the modified modern research cell lines) lead away from VERO E6 when an small carnivore/bat zoonosis scenario should simultaneously increase all primate tropism as the virus evolve in humans. It should raise, and not drop, VERO E6 tropism.
