Abstract
The present invention is directed to novel nucleotide and amino acid sequences of Porcine Parainfluenza Virus Type 1 (“PPIV-1”), including novel genotypes thereof, all of which are useful in the preparation of immunogenic compositions and vaccines for treating and preventing disease in swine.
Claims55
An immunogenic composition comprising an inactivated or live, attenuated porcine parainfluenza virus type 1 (PPIV-1), wherein said virus comprises an RNA nucleotide sequence that is at least 90%, 95%, 96%, 97%, 98%, 99%, or 99.5% identical to the DNA sequence set forth in SEQ ID NOs:
- 1, 14, or 15.
A method for inducing an immune response against porcine parainfluenza virus type 1 (PPIV-1) in swine comprising:
- administering to a swine an immunogenic composition comprising an inactivated or live, attenuated porcine parainfluenza virus type 1 (PPIV-1), wherein said virus comprises an RNA nucleotide sequence that is at least 90%, 95%, 96%, 97%, 98%, 99%, or 99.5% identical to the DNA sequence set forth in SEQ ID NOs:
- 1, 14, or 15.
An isolated porcine parainfluenza virus type 1 (PPIV-1), wherein said virus comprises an RNA nucleotide sequence that is at least 95% identical to the DNA nucleotide sequence set forth in SEQ ID NO:
- 14, and that encodes one or more of the following amino acid features:
- (a) an isoleucine at position 102 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- and/or
- (b) a threonine at position 406 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof.
An isolated porcine parainfluenza virus type 1 (PPIV-1), wherein said virus comprises an RNA nucleotide sequence that is at least 95% identical to the DNA nucleotide sequence set forth in SEQ ID NO:
- 15, and that includes one or more of the following amino acid features:
- (a) a lysine at position 300 of phosphoprotein as determined by reference to SEQ ID NO:
- 5, or a conservative substitution thereof;
- (b) an isoleucine at position 102 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- (c) an aspartic acid at position 349 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- (d) a threonine at position 406 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- and/or
- (e) an isoleucine at position 460 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof.
A vaccine composition comprising an inactivated or live, attenuated porcine parainfluenza virus type 1 (PPIV-1) and a suitable pharmaceutical carrier, wherein said virus comprises an RNA nucleotide sequence that is at least 90%, 95%, 96%, 97%, 98%, 99%, or 99.5% identical to the DNA sequence set forth in SEQ ID NOs:
- 1, 14, or 15.
A vaccine composition comprising an attenuated strain of porcine parainfluenza virus type 1 (PPIV-1) and a suitable pharmaceutical carrier, wherein said strain of PPIV-1 comprises a nucleic acid sequence which encodes one or more proteins with one or more substitutions at the following positions:
- (a) a lysine at position 300 of phosphoprotein as determined by reference to SEQ ID NO:
- 5, or a conservative substitution thereof;
- (b) an isoleucine at position 102 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- (c) an aspartic acid at position 349 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- (d) a threonine at position 406 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof;
- and/or
- (e) an isoleucine at position 460 of hemagglutinin-neuraminidase protein as determined by reference to SEQ ID NO:
- 11, or a conservative substitution thereof.
A method of preparing a live, attenuated porcine parainfluenza virus type 1 (PPIV-1) comprising:
- passaging a virus in cell culture, wherein said virus comprises an RNA nucleotide sequence that is at least 90%, 95%, 96%, 97%, 98%, 99%, or 99.5% identical to the DNA sequence set forth in SEQ ID NOs:
- 1, 14, or 15.
A method for determining if a population of swine is in need of vaccination against porcine parainfluenza virus type 1 (PPIV-1) infection:
- collecting a biological sample from one or more swine of said population;
- and
- detecting the presence of said virus in said biological sample, wherein said virus comprises an RNA nucleotide sequence that is at least 90%, 95%, 96%, 97%, 98%, 99%, or 99.5% identical to the DNA sequence set forth in SEQ ID NO:
- 1.
