title: Characterization of some ungrouped viruses.
abstract: Bangui, Bobaya, Kowanyama, Upolu and Zinga are enveloped spherical RNA viruses sensitive to ether and acid pH; morphologically resembling Bunyaviridae, their diameters range from 90 to 100 nm and their bouyant density is 1.17 to 1.18 g/ml in sucrose. St. Floris, a bunya-like virus, serologically related to Rift Valley Fever, has a diameter ranging from 90 to 110 nm. Triniti, Zingilamo, IPYM 120 and virus strain AnB4268 are enveloped spherical RNA viruses sensitive to ether and acid pH, have diameters of 65, 55, 55 and 60 nm and bouyant densities of 1.18, 1.24, 1.20 and 1.18 g/ml in sucrose, respectively; morphologically they resemble Togaviridae. Salanga is a poxvirus measuring 190 X 225 nm. Virus strain AnY1444 is a spherical, non-enveloped RNA virus measuring 85 nm, morphologically resembling Reoviridiae; it is restraint to both ether and acid pH and shows two-peak densities of 1.32 and 1.36 g/ml in caesium chloride. Bangoran, Keuraliba and Yata resemble Rhabdoviridae measuring 60 X 175, 65 X 195 and 60 X 185 nm, respectively.
