The effects of some known ionic and nonionic detergents as well as that of a novel nonionic detergent MESK on various enveloped viruses were investigated. It was found that nonionic detergens (MESK, Triton X-100, octyl-beta-D-glucopyranoside) selectively solubilize glycoproteins of enveloped viruses. The most mild selective action is exerted by the nonionic detergent MESK. Using this detergent, pure preparations of glycoproteins of influenza, parainfluenza, equine Venezuela encephalomyelitis, rabies, vesicular stomatitis and herpes viruses were obtained. The procedure of isolation of purified glycoproteins includes incubation of viral suspensions with MESK, removal of subviral structures by centrifugation and purification of glycoproteins from detergent admixtures by dialysis. Purified glycoproteins retain their native structure and a high biological activity and immunogenicity. MESK seems to be due a perspective tool in the production of subunit vaccines.

A cDNA clone of mRNA for rabies virus matrix (M) protein has been identified. The clone hybridizes to an mRNA species from rabies virus-infected cells, whose size correlates to the size of the M protein in rabies virions, and selects an mRNA that translates into a polypeptide corresponding in size to M protein. The nucleotide sequence of the cloned cDNA was determined and from this a complete amino acid sequence for M protein was deduced. The deduced sequence of 202 amino acids bears no detectable sequence homology with vesicular stomatitis virus M protein although these proteins may share functional homology.

Sera from more than 100 alpacas (Lama pacos) from the Peruvian southern sierra were examined for antibodies to 8 viruses known to infect other domestic animals. On the basis of these serologic findings and previously published serologic or clinical data, it is now known that the alpaca can be infected with the following viruses: parainfluenza-3, bovine respiratory syncytial virus, bovine herpesvirus-1, bluetongue virus, border disease virus, influenza A virus, rotavirus, rabies virus, vesicular stomatitis virus, foot-and-mouth disease virus, and contagious ecthyma virus.

Apparent interferon-mediated persistent infection of rabies virus (HEP-Flury strain) was established in a human neuroblastoma SYM-I (clone K-104) cell line, which had the ability to produce interferon. This infection produced variable but small amounts of progeny virus and interferon (up to 100 IU/ml), and resisted superinfection with vesicular stomatitis virus (VSV) and Sindbis virus as well as homologous rabies virus. The treatment of this infection with anti-interferon antibody stimulated virus replication and extensive c.p.e. However, some cells survived and grew rapidly without any sign of c.p.e. These produced increased amounts (100 to 1000 times) of infectious and DI particles in the presence of anti-interferon antibody, becoming susceptible to superinfection with VSV but remaining resistant to the original rabies virus. Small plaque mutants appeared and replaced the original virus during the long-term cultivation of the persistent infection. Several mutants tested were all identified as Sdi (DI-resistant) mutants, suggesting that the persisting viruses were endowed by the Sdi mutation with a selective advantage over the original virus even in interferon-mediated persistent infections.

Recent advances in molecular genetics have led to the possibility of using large DNA viruses, such as vaccinia virus, as a biological delivery system for immunizing man against unrelated disease-causing agents. When live vaccinia virus recombinants expressing the hepatitis B virus surface antigen (HBsAg), the influenza A virus haemagglutinin, the herpes simplex virus (HSV) type 1 D glycoprotein, the rabies virus G glycoprotein and the vesicular stomatitis virus G glycoprotein were used for immunization, animals were protected upon challenge with the appropriate pathogenic agent. A major concern with using such vaccines, however, stems from the previously documented vaccinia virus-associated post-immunizing complications. We present here experimental evidence that thymidine kinase-negative (TK-) vaccinia virus recombinants, constructed by inserting a variety of DNA coding sequences into the vaccinia virus tk gene, are less pathogenic for mice than wild-type virus.

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.

Partial acid hydrolysates of the [(32)P]phosphate- or [(3)H]serine-labeled proteins of purified vesicular stomatitis, rabies, Lagos bat, Mokola, or spring viremia of carp virions and of purified intracellular nucleocapsids of these viruses have been analyzed by paper electrophoresis for the presence of phosphorylated amino acids. Both phosphoserine and phosphothreonine, with the former predominant, were present in virion and nucleocapsid preparations that contained phosphoproteins. An exception was the fish rhabdovirus, which contained only phosphoserine. When vesicular stomatitis or rabies virus proteins were phosphorylated in a cell-free system by the virion-associated protein kinase and analyzed for the presence of phosphorylated amino acid residues, phosphoserine was again found to be more abundant than phosphothreonine. After in vitro protein phosphorylation, another phospho-compound, possibly a third phosphoamino acid, was detected in the partial acid hydrolysates of these viruses.

Infection of enucleated TC-7 monkey cells with rabies virus resulted in the synthesis of virus-directed RNA and the production of rabies antigens but not of infectious virus. The yield of infectious vesicular stomatitis virus from enucleated TC-7 cells, on the other hand, was almost as high as that from intact cells. Inhibition of the mitochondrial functions of enucleated cells by treatment with ethidium bromide did not influence the development of rabies antigens or the production of infectious vesicular stomatitis virus.

We analyzed cell extracts from BHK(21) cells infected with vesicular stomatitis virus (VSV) and rabies virus for in vitro RNA polymerase activity. Cells infected with VSV B virions exhibited several complexes with in vitro RNA polymerase activity in sucrose gradients. These complexes synthesize VSV transcriptase product (4 to 18S) polyadenylated in RNA complementary to virion RNA. Cells infected with a high multiplicity of B virions and T particles show only one RNA polymerase complex active in vitro. This complex sediments at 110S and makes only small (2S) RNA. Carrier BHK(21) cells persistently noncytopathically infected with VSV contain several complexes active in RNA polymerase, but both exhibit very low activity. Cytoplasms of cells noncytopathically infected with rabies virus also show very low levels of a complex containing RNA polymerase activity. No transcriptase nor any other in vitro polymerase activity could be found associated with purified rabies virions, although they do carry out primary transcription in cells treated with actinomycin D and cycloheximide before infection.
