Eastern equine encephalitis virus - Thin section electron microscopy of infected cell culture.
Eastern equine encephalitis virus. This is an ultra-thin section of a Vero cell culture infected for 24 hours. Virions have accumulated in the space between cells as a result of budding from the surface membrane of infected cells. In this infection very large numbers of the 60 nm (nanometer) spherical virions are produced quickly and as quickly the cells are destroyed. Magnification approximately x70,000.
