Assembly and Budding of Ebolavirus
Figure 5
Different Modes of Ebolavirus Budding
(A) Filamentous virions, approximately 80 nm in diameter, budding from the cell surface vertically or (B) horizontally. (C, F, and I, early stage; D, G and J, intermediate stage; E, H, and K, final stage).
(C–E) The various steps of horizontal budding observed by SEM. Longitudinal (F–H) and transverse (I–K) sections of virions at different stages of horizontal budding visualized by TEM. Bars, 3 μm (A and B), 200 nm (C–H), or 100 nm (I–K).
