Abstract
The invention relates to a new group of viruses, designated SVI. Isolated SVI viruses, polynucleotides and proteins from SVI viruses, and antibodies which bind SVI virus and SVI viral proteins are provided. The polynucleotides, proteins, and antibodies of the invention may be used to detect SVI virus or infection by SVI virus in a susceptible individual. Additionally, polynucleotides of the invention may be inserted into recombinant expression vectors recombinant production of viral proteins.
Claims18
A composition comprising isolated SVI virus.
An isolated polynucleotide selected from the group consisting of:
- an isolated polynucleotide selectively hybridizable with the nucleotide sequence of any of SEQ ID NO:
- 1 through SEQ ID NO:
- 5;
- a complement of an isolated polynucleotide selectively hybridizable with the nucleotide sequence of any of SEQ ID NO:
- 1 through SEQ ID NO:
- 5;
- an isolated polynucleotide encoding an isolated SVI protein or fragment thereof;
- and
- a complement of an isolated polynucleotide encoding an isolated SVI protein or fragment thereof;
- wherein the nucleotide sequence of said isolated polynucleotide is distinct from the genomic sequences of TTV strains SANBAN and TUS01.
A composition comprising:
- an isolated SVI protein or fragment thereof, wherein said isolated SVI protein or fragment thereof is serologically distinct from proteins of TTV strains SANBAN and TUS01.
A vaccine composition comprising:
- an isolated SVI protein or fragment thereof, wherein said isolated SVI protein or fragment thereof is serologically distinct from proteins of TTV strains SANBAN and TUS01;
- and
- a pharmaceutically acceptable excipient.
An expression vector comprising an isolated polynucleotide encoding an SVI protein or fragment thereof, wherein said SVI protein or fragment thereof is serologically distinct from proteins of TTV strains SANBAN and TUS01.
An expression vector comprising an isolated polynucleotide, wherein transcription of said isolated polynucleotide results in the production of an SVI antisense polynucleotide, wherein said SVI antisense polynucleotide is not an antisense polynucleotide which will form a duplex with an RNA transcript from TTV strains SANBAN and TUS01.

A method for detecting SVI virus, comprising:
- contacting a sample with an antibody which binds to SVI virus or a protein thereof, wherein said antibody does not bind to TTV strains SANBAN and TUS01 or proteins thereof;
- and
- detecting complexes of said antibody and SVI virus or protein thereof.
A method for detecting SVI virus, comprising:
- contacting a sample with a probe polynucleotide which selectively hybridizes to an SVI polynucleotide, wherein said probe does not selectively hybridize with TTV strain SANBAN polynucleotides or TTV strain TUS01 polynucleotides;
- and
- detecting hybridization of said probe with an SVI polynucleotide.
An antibody that binds to an SVI virus wherein the genome of said virus contains any one of SEQ ID NO:
- 1, SEQ ID NO:
- 2, SEQ ID NO:
- 3, SEQ ID NO:
- 4, AND SEQ ID NO:

- 1, SEQ ID NO:
- 2, SEQ ID NO:
- 3, SEQ ID NO:
- 4, AND SEQ ID NO:
- 5;
- and
- detecting complexes of said antibody and SVI virus or protein thereof.
A method for detecting SVI virus, comprising:
- contacting a sample with a probe polynucleotide that selectively hybridizes to a target polynucleotide wherein the target polynucleotide is a portion of a viral genome, and said viral genome contains any one of SEQ ID NO:
- 1, SEQ ID NO:
- 2, SEQ ID NO:
- 3, SEQ ID NO:
- 4, AND SEQ ID NO:
- 5;
