SummaryA field isolate of Sendai virus, the Hamamatsu strain, was far more virulent in mice than the prototype Z strain. The Hamamatsu strain replicated more efficiently in the mouse lung than the Z strain, causing deteriorating lung lesions. Nucleotide sequence analysis of the HN, F and M genes revealed that the Hamamatsu strain was divergent from the prototype Z, Harris and Fushimi strains.

Identification of Mutations Associated with Attenuation of Virulence of a Field Sendai Virus Isolate by Egg Passage
TLDR
To determine the molecular basis for the attenuation of SeV pathogenicity by egg passage, entire genomes of representative SeV clones isolated during egg passages were sequenced and the significance of the mutations detected in the leader as well as in the L and HN genes was discussed.
Masking of the contribution of V protein to Sendai virus pathogenesis in an infection model with a highly virulent field isolate.
TLDR
The V protein seems to be potentially functional in the highly virulent Hamamatsu strain and to be prominent if virus replication is restricted, although it appears that the V protein is nonsense in a field isolate of Sendai virus.
Sendai virus, the mouse parainfluenza type 1: a longstanding pathogen that remains up-to-date.
TLDR
A review of Sendai virus, the murine parainfluenza virus type 1, aimed at drawing an exhaustive picture of this multifaceted pathogen.
Sendai Virus and Pneumonia Virus of Mice (PVM)
TLDR
Sendai virus infection of mice is investigated in some detail because it is a naturally occurring respirovirus of mice and therefore an excellent paradigm for a viral genus that causes significant morbidity in many mammalian species, including humans.
Passage of a Sendai Virus Recombinant in Embryonated Chicken Eggs Leads to Markedly Rapid Accumulation of U-to-C Transitions in a Limited Region of the Viral Genome
TLDR
The results suggest that a lack of C proteins could lead unexpectedly to strong selective pressures, and that the C proteins might play more critical roles in SeV replication than ever reported.
Contribution of the leader sequence to homologous viral interference among Sendai virus strains.
TLDR
Results indicate that homologous interference is partly dependent on the promoter sequence and suggest involvement of promoter activity for genome amplification related to host factors in viral interference, and suggest suppression of closely related human paramyxoviruses.
Conserved and Non-Conserved Regions in the Sendai Virus Genome: Evolution of a Gene Possessing Overlapping Reading Frames
TLDR
The entire genome of a virulent field isolate of Sendai virus, the Hamamatsu strain, is sequenced, and regions where changes were permissive and non-permissive, and the experimentally determined functional region were found to be conserved, showing that important regions for function were conserved during evolution.
A new paramyxovirus, Tianjin strain, isolated from common cotton-eared marmoset: genome characterization and structural protein sequence analysis
TLDR
Pairwise comparisons of amino acid identities and phylogenetic analysis with homologous sequences of known SeVs demonstrated that Tianjin strain represented a new evolutionary lineage of SeV.
Prevalence of specific neutralizing antibodies against Sendai virus in populations from different geographic areas: Implications for AIDS vaccine development using Sendai virus vectors
TLDR
To quantify SeV neutralizing antibodies (NAb) in human serum, a sensitive virus neutralization assay was developed using a SeV vector encoding green fluorescent protein and a significant correlation was observed between hPIV-1 ELISA and SeV NAb titers.
Illumination of Parainfluenza Virus Infection and Transmission in Living Animals Reveals a Tissue-Specific Dichotomy
TLDR
A dichotomy between PIV infection in the URT and trachea versus the lungs is revealed and a new model for studies of pathogenesis, development of live virus vaccines, and testing of antiviral therapies is defined.

Variation of Virulence and Other Properties among Sendai Virus Strains
TLDR
The results indicate that Sendai virus prevailing in laboratory rodents is not homogenous with respect to virulence and some other properties.
Newcastle disease virus evolution. II. Lack of gene recombination in generating virulent and avirulent strains.
TLDR
The present study strongly supports the importance of the previously identified signals for gene expression and for the proteolytic activation of the gene product and identifies three distinct evolutionary lineages correlating with the virulence as expressed by mean death time (MDT) for chick embryo.
ON THE CHARACTERISTICS OF A NEWLY-ISOLATED HEMAGGLUTINATING VIRUS FROM MICE
TLDR
A new form of virus newly-isolated from mice and considered to belong to the MNI group was treated in present report and several characteristics were described, considered to be helpful in analysing the inter-relationship between this form ofirus and the influenza viruses.
Immediate protection of mice from lethal wild-type Sendai virus (HVJ) infections by a temperature-sensitive mutant, HVJpi, possessing homologous interfering capacity.
TLDR
HVJpi is an unique virus mutant which is capable of protecting mice from lethal Sendai virus infections by its interfering capacity immediately after inoculation and then by the induction of virus-specific immune responses.
Sendai virus.
TLDR
SeV naturally affects mice, rats, and hamsters, and an outbreak in swine occurred in the early 1950s in Japan and further serological testing in the 1960s was negative in Japan.
Nucleotide and deduced amino acid sequence of hemagglutinin-neuraminidase genes of human type 3 parainfluenza viruses isolated from 1957 to 1983.
TLDR
Although the overall amino acid homology among HN proteins is very high, most variability is concentrated in domains at the carboxyl and amino terminus, which may reflect both functional and structural constraints on different HN domains and the epidemiologic features of PIV3 infection.
Pneumopathogenicity of a Sendai virus protease-activation mutant, TCs, which is sensitive to trypsin and chymotrypsin
TLDR
A protease-activation mutant of Sendai virus, TCs, was isolated from a trypsin-resistant mutant, TR-5, and Activation of TCs in the lungs of mice occurred less efficiently than that of the wild type, and TCs caused a less severe pneumopathogenicity than did the wild-type virus.
Newcastle disease virus evolution. I. Multiple lineages defined by sequence variability of the hemagglutinin-neuraminidase gene.
TLDR
Analysis of hemagglutinin-neuraminidase gene sequence among 13 strains of Newcastle disease virus isolated over the last 50 years demonstrated the existence of at least three distinct lineages, which must have co-circulated for considerable periods.
Cloning and sequencing of the matrix protein gene (M) of Sendai virus (strain Fushimi)
TLDR
The cDNA for the complete matrix protein gene (M) of Sendai supported by the 'Deutsche Forschungsgemeinschaft, virus strain Fushimi (ATCC no. VR-105, Sendai/52) (1) was cloned and sequenced by using specific oligonucleotide primers'.
Pneumotropism of Sendai Virus in Relation to Protease-Mediated Activation in Mouse Lungs
TLDR
The overall results suggest that some activating mechanism for the progeny virus of wild-type Sendai virus exists in the lung of mice and the principle (activator) responsible for this phenomenon has a character similar to trypsin.
