Distinction between Bunyaviridae genera by surface structure and comparison with Hantaan virus using negative stain electron microscopy.

Ultrastructural studies of glutaraldehyde-fixed viruses of the Bunyaviridae were performed by negative-stain electron microscopy. The surface structure of viruses of each genus was compared with that of the other genera and with Hantaan virus, the prototype of a proposed new genus of Bunyaviridae. Viruses of each genus had a surface structure distinct for that genus.
