FIG. 8.

Distribution of virus particles. Numbers of virus particles present in the different compartments of FDL51-infected Vero cells at 24 h postinfection were determined. Particles were counted in electron micrographs of 20 randomly selected cells for wild-type and FDL51-infected cells. Bars show the average particle numbers in each compartment. (a) Nucleocapsids in the nucleus; (b) enveloped nucleocapsids in the perinuclear space; (c) nucleocapsids in the cytoplasm; (d) enveloped mature virions in the cytoplasm; (e) extracellular mature virions on the outer surface of the plasma membrane.
