Abstract
The present invention relates to recombinant bovine parainfluenza virus (bPIV) cDNA or RNA which may be used to express heterologous gene products in appropriate host cell systems and/or to rescue negative strand RNA recombinant viruses that express, package, and/or present the heterologous gene product. The chimeric viruses and expression products may advantageously be used in vaccine formulations including vaccines against a broad range of pathogens and antigens.

A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of a Kansas-strain bovine parainfluenza virus type 3 genome;
- and
- (ii) one or more heterologous sequences, wherein said one or more heterologous sequences have been added to said virus genome or have been substituted for nucleotide sequences of said virus genome, wherein said heterologous sequence is added at a nucleotide position of Kansas-strain bovine parainfluenza virus type 3 selected from the group consisting of nucleotide position 5041, the HN gene, and nucleotide position 8529.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome comprising nucleotides 1–5041 and nucleotides 8529–15,456 of the genome of Kansas strain bovine parainfluenza virus type 3;
- and
- (ii) F and FIN gene sequences of human parainfluenza virus type 3.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome;
- and
- (ii) the F and UN gene sequences of human parainfluenza virus type 3, wherein (i) PCR amplification of nucleotide 5,255 to 6,255 of the chimeric parainfluenza virus results in a DNA fragment that is recognized by restriction endonucleases Sac I and Bgl II;
- and (ii) PCR amplification of nucleotide 9,075 to 10,469 of the chimeric parainfluenza virus results in a DNA fragment that is recognized by restriction endonucleases Pvu II and Bam HI.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome comprising nucleotides 1–5041 and nucleotides 8529–15,456 of the genome of Kansas strain bovine parainfluenza virus type 3;
- and
- (ii) one or more sequences derived from RSV, PIV, New Castle Disease virus, Sendai virus, Infectious Laryngotracheitis virus or influenza.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome comprising nucleotides 1–5041 of the genome of Kansas-strain bovine parainfluenza virus type 3;
- and
- (ii) one or more sequences derived from RSV, PIV, New Castle Disease virus, Sendai virus, Infectious Laryngotracheitis virus or influenza.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome;
- and
- (ii) one or more sequences derived from RSV, PIV, New Castle Disease virus, Sendai virus, Infectious Laryngotracheitis virus or influenza, and wherein said sequences have been added at a nucleotide position of Kansas-strain bovine parainfluenza virus type 3 selected from the group consisting of nucleotide position 5041, the HN gene, and nucleotide position 8529.
A method of administration of a recombinant parainfluenza virus to a subject comprising:
- administering to the subject a recombinant parainfluenza virus, said virus comprising:
- (i) nucleotide sequences of Kansas-strain bovine parainfluenza virus type 3 genome comprising nucleotides 8,529–15,456 of the genome of Kansas-strain bovine parainfluenza virus type 3;
- and
- (ii) one or more sequences derived from RSV, PIV, New Castle Disease virus, Sendai virus, Infectious Laryngotracheitis virus or influenza.
