Morphological changes of cell cultures infected with WR and Wyeth strains at 3 days post-infection. (A) Plaque formation in Vero E6 and EA.hy926 cells. (B) Morphological changes of CV-1, primary mouse lung cells (Lung), MLEC and primary mouse kidney cells (Kidney) at 200 × magnification. Cells were infected with WR or Wyeth strains at m.o.i. 1 and observed after 2 days post-infection.
