 With the multiplicity of infection of 2, approximately 1/3 of the DCs begin to express encoded SeV proteins 8 hours after infection.This proportion increases to 2/3, 24 hours and decreases to 1/3, 48 hours after infection.SeV demonstrates high cytopathic effect on DCs; the virus can kill a third of DC even with a very low multiplicity of infection such as 0.5.
