Figure 5. Vero cells infected with severe acute respiratory syndrome–associated coronavirus. A) An atomic force microscopy image of thickened, layered appearance of the edge of the cells (arrows), where active virus extrusion occurs. Arrowheads indicate the virus particles. B) The layered cell edge (arrows) seen by scanning electron microscopy. Virus particles extrude from the layered surfaces.
