Electron microscopic and antigenic studies of uncharacterized viruses. III. Evidence suggesting the placement of viruses in the familyReoviridae

Abstract
Summary This is the last of three papers describing the use of electron microscopy and antigenic tests intended to characterize and place in taxa more than 60 previously unclassified viruses. The first paper describes the viruses we classified as members of the familiesArenaviridae, Paramyxoviridae, orPoxviridae. The second paper describes those classified as members of the virus familyBunyaviridae. Another paper, published separately, discusses viruses classified as members of the familyRhabdoviridae. In this paper we report that electron microscopy provided sufficient evidence to provisionally place 14 viruses in the familyReoviridae. By using serologic methods, we placed Minnal virus in the Umatilla serogroup and established new antigenic groups for seven other viruses (Ieri, Picola, Arkonam, Tembe, Fomede, Wongorr, and Gomoka). No antigenic relationships were determined for six other viruses (Andasibe, Itupiranga, Kammavanpettai, Lake Clarendon, Matucare, and Ndelle) provisionally placed in the familyReoviridae.
