In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratory syndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading(More)
To study the replication of Nipah virus (NiV), a minigenome replication assay that does not require the use of infectious virus was developed. The minigenome was constructed to encode a NiV vRNA analogue containing the gene for chloramphenicol acetyltransferase (CAT) under the control of putative NiV transcription motifs and flanked by the NiV genomic(More)
Severe acute respiratory syndrome (SARS) was first described during a 2002-2003 global outbreak of severe pneumonia associated with human deaths and person-to-person disease transmission. The etiologic agent was initially identified as a coronavirus by thin-section electron microscopic examination of a virus isolate. Virions were spherical, 78 nm in mean(More)
The sequences of the nucleoprotein (N) and hemagglutinin (H) genes are routinely used for molecular epidemiologic studies of measles virus (MV). However, the amount of genetic diversity contained in other genes of MV has not been thoroughly evaluated. In this report, the nucleotide sequences of the phosphoprotein (P) genes from 34 wild-type strains(More)
Nipah virus (NiV) is a recently emergent, highly pathogenic, zoonotic paramyxovirus of the genus Henipavirus. Like the phosphoprotein (P) gene of other paramyxoviruses, the P gene of NiV is predicted to encode three additional proteins, C, V and W. When the C, V and W proteins of NiV were tested for their ability to inhibit expression of the chloramphenicol(More)
The nucleocapsid protein (N, 525 amino acids) of measles virus plays a central role in the replication of the viral genomic RNA. Its functions require interactions with itself and with other viral components. The N protein encapsidates genomic RNA, a function reflected in its ability to self-assemble into nucleocapsid-like particles in the absence of other(More)
The C and V proteins of the measles virus (MV) have been shown to block the signaling of type I and II interferon (IFN-alpha/beta and IFN-gamma). The relative contribution of the C and V proteins to the inhibition of IFN signaling and the extent to which this activity differs in attenuated or wild-type strains of MV remains undefined. This study presents a(More)
The complete genomic sequences of 9 measles vaccine strains were compared with the sequence of the Edmonston wild-type virus. AIK-C, Moraten, Rubeovax, Schwarz, and Zagreb are vaccine strains of the Edmonston lineage, whereas CAM-70, Changchun-47, Leningrad-4 and Shanghai-191 were derived from 4 different wild-type isolates. Nucleotide substitutions were(More)
Lewis rats immunized with recombinant vaccinia virus expressing the nucleocapsid (N) protein of measles virus were protected from encephalitis when subsequently challenged by intracerebral infection with neurotropic measles virus. Immunized rats revealed polyvalent antibodies to the N protein of measles virus in the absence of any neutralizing antibodies as(More)
