Virus Morphology Size and Structure

F. A. Murphy and S. G. Whitfield (1975) have given a detailed account of the morphology and morphogenesis of the virion and have related it to the other members of the Arenavirus group. The virus particles, on budding from the cell membrane, may be round, oval, or pleomorphic, with mean diameters of 110 to 130 nanometers and with spike-covered envelopes. The center of the particle contains variable numbers of fine granulations, measuring 20 to 25 nanometers, a characteristic that prompted the name Arenavirus. The nucleosome consists of single-stranded RNA. In 1984, F. Lehmann-Grube furnished a detailed account of the development and pathogenetic characteristics of the Arena viridae.
