Recently accumulated knowledge allows more precise comparison of the structural (and possibly evolutionary) relationships of several different animal rhabdoviruses: vesicular stomatitis virus, rabies virus, Kern Canyon virus, and spring viremia of carp virus. Each virus is composed primarily of a glycoprotein, an RNA-associated nucleoprotein, and one or two membrane proteins. Vesicular stomatitis virus group viruses contain lesser amounts of two additional distinct polypeptides, NS and L. The separate viruses undergo structural polypeptide phosphorylation in vivo according to characteristic patterns. In vesicular stomatitis virus the NS protein is selectively phosphorylated. In rabies group viruses and in spring viremia of carp virus, the nucleoprotein is the predominant phosphoprotein; in these viruses only the phosphorylated moiety is selectively cleaved off with trypsin. In Kern Canyon virus, only membrane protein and glycoprotein are weakly phosphorylated. Each virus possesses a virion-bound protein kinase. Vesicular stomatitis virus group viruses, Kern Canyon virus, and spring viremia of carp virus only contain virion-bound transcriptases of respectively decreasing levels of activity demonstrable in vitro. Vesicular stomatitis and Kern Canyon viruses replicate efficiently in enucleated cells; rabies virus does not. Based upon these observations, it is suggested that vesicular stomatitis virus may represent the most highly evolved of these rhabdoviruses, whereas spring viremia of carp and Kern Canyon viruses may represent "evolutionary links" between the vesicular stomatitis and rabies virus groups.

Thermal inactivation of rabies and several other rhabdoviruses was studied using virus suspended in several different diluents. Rabies serogroup viruses were more stable than Kern Canyon or vesicular stomatitis viruses. Limited studies of two fish rhabdoviruses requiring low temperatures (less than 33 C) for replication indicated that they were not markedly more thermolabile than rabies virus. Bovine serum protein components in complex cell culture media stabilized virus at 56 C, but at temperatures of less than or equal to 37 C, sodium tris (hydroxymethyl)-aminomethane (NT) buffer containing ethylenediaminetetraacetic acid (EDTA) (NTE) was a much more efficient stabilizer of virus infectivity. Chelating agents EDTA and ethyleneglycol-bis-(beta-aminoethyl ether)tetraacetic acid were equally efficient in protection of rabies virus infectivity; the effect of each was lost when excess Ca2+ was added. Bovine serum in NT or NTE buffers produced a thermostabilizing effect at 37 C not provided by the same serum concentration in complex cell culture media. Bovine serum was more efficient than EDTA in stabilizing virus infectivity during repeated cycles of freezing and thawing.

A ribonucleic acid (RNA)-dependent RNA polymerase has been demonstrated in Kern Canyon virus (KCV) particles. The RNA product of the KCV polymerase hybridizes to KCV viral RNA. The properties of this viral enzyme have been characterized and compared with those of vesicular stomatitis virus (VSV). RNA polymerases from both viruses require similar conditions of temperature, pH, and detergent and magnesium concentrations for maximal synthesis of RNA. The RNA polymerase contained in the virion of KCV was more dependent on the presence of a sulfhydryl agent than was the VSV enzyme. Under optimal conditions, the specific activity of the VSV polymerase is about twenty-five times as great as that of KCV.

Rabies virus neutralizing antibodies were produced in vitro by the exposure of mouse spleen cells to live and inactivated rabies virus suspensions and to sheep erythrocytes coated with rabies virus. These antibodies did not neutralize two other rhabdoviruses: Kern Canyon and vesicular stomatitis viruses, and were precipitable by treatment with an antiserum to mouse IgG. Removal of "glass-adhering" cells from mouse spleen cell suspensions abolished the antibody response, which could be restored by the addition of mouse peritoneal exudate cells, rich in macrophages.

The development of the virus of bovine ephemeral fever in mouse brain has been studied by electron microscopy. The virus particles are bullet-shaped, 70 by 145 nm, and slightly tapered toward the rounded end. The outer envelope is closely apposed to an electron-dense shell, about 12 nm thick, but no other internal structure is visible. The virus strains studied bud from the marginal membranes of neurones, but intracytoplasmic development, possibly aberrant, was also observed with one strain. Ephemeral fever virus is thus obviously a rhabdovirus, with points of resemblance to vesicular stomatitis, Flanders-Hart Park, and Kern Canyon viruses on the one hand, and to rabies virus on the other, but is structurally distinct from any of these.

Kern Canyon virus (KCV), propagated in suckling mouse brain and cell culture, was examined by negative contrast and thin section electron microscopy. The virus was found to exhibit symmetry similar to other viruses of the Stomatoviridae family. The bullet-shaped virus particles had a mean length of 132 micron and were 73 micron in diameter. Cross striations, axial channels and surface projections were prominent. Virus maturation occurred on marginal cytoplasmic membranes with mature virions accumulating extracellularly. Complement fixation, virus neutralization, and immunodiffusion tests comparing KCV with other bullet-shaped viruses of animals confirmed the distinct antigenicity of the virus, whereas comparison of KCV with vesicular stomatitis virus in a density gradient ultracentrifugation experiment emphasized the physical basis for including KCV within the Stomatoviridae family of viruses.
