Effects of magnification, MOI, and post-infection time on the visualization of viral-induced CPE in various cell lines. (a) Vero cells infected with SARS-CoV-2 at an MOI of 0.01, captured 46 h post-infection. Images display the cells at varying magnifications. (b) MDBK cells infected with BoAHV-1 at 20x magnification, 24 h post-infection, with varying MOIs. (c) MDBK cells infected with BoGHV-4 (DN-599) at 20x magnification and an MOI of 0.001 at various hours post-infection.
