Abstract: Chimeric human-bovine respiratory syncytial virus (RSV) are infectious and attenuated in humans and other mammals and useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric RSV genome or antigenome which includes a partial or complete human or bovine RSV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different RSV strain. Chimeric human-bovine RSV of the invention include a partial or complete “background” RSV genome or antigenome derived from or patterned after a human or bovine RSV strain or subgroup virus combined with one or more heterologous gene(s) or genome segment(s) of a different RSV strain or subgroup virus to form the human-bovine chimeric RSV genome or antigenome.

Abstract: Recombinant respiratory syncytial virus (RSV) having the position of genes shifted within the genome or antigenome of the recombinant virus are infectious and attenuated in humans and other mammals. Gene shifted RSV are constructed by insertion, deletion or rearrangement of genes or genome segments within the recombinant genome or antigenome and are useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a recombinant RSV genome or antigenome wherein a gene or gene segment is shifted to a more promoter-proximal or promoter-distal position within the genome or antigenome compared to a wild type position of the gene in the RSV gene map. Shifting the position of genes in this manner provides for a selected increase or decrease in expression of the gene, depending on the nature and degree of the positional shift.

Abstract: The present invention relates i.a. to Bovine Respiratory Syncytial Viruses that are not capable of expressing a functional SH-protein and/or G-protein due to a mutation in the genes encoding the said proteins. Also the invention relates to diagnostic test kits for discriminating wild-type Bovine Respiratory Syncytial Viruses from Bovine Respiratory Syncytial Viruses according to the invention and to methods for the discrimination between those viruses.

Abstract: Recombinant respiratory syncytial virus (RSV) having the position of genes shifted within the genome or antigenome of the recombinant virus are constructed by insertion, deletion or rearrangement of genes or genome segments within the recombinant genome or antigenome and are useful for eliciting an anti-RSV immune response. Shifting the position of genes in this manner provides for a selected increase or decrease in expression of the gene. In one embodiment, expression of RSV glycoproteins is upregulated by shifting one or more glycoprotein-encoding genes to a more promoter-proximal position. Genes of interest for manipulation to create gene position-shifted RSV include any of the NS1, NS2, N, P, M, SH, M2(ORF1), M2(ORF2), L, F or G genes or a genome segment that may be part of a gene or extragenic. Additional mutations and nucleotide modifications are provided within gene position-shifted RSV to yield desired phenotypic and structural effects.
