Figure. Ultrastructure of the new rhabdoviruses in infected Vero cells. A. Virions of isolate RI-175 budding from the surface of a Vero cell and from cell surface projections (arrows). Arrowheads mark cross-sections of virions. The virion indicated with a large arrow is enlarged in B. B. A virion of isolate RI-175 budding from host cell plasmalemma into an extracellular space. C. Details of the virion ultrastructure of isolate RI-175, showing spiral packaging of the nucleocapsid and its tubular structure in the cross-sections (arrows). D. A virion of the isolate CT-114 budding into an intracytoplasmic vacuole. Bar = 100 nm.
