Nucleic acid and amino acid sequences of infectious salmon anaemia virus and their use as vaccines
View Patent ↗The present invention provides the use of nucleic acid sequences and/or amino acid sequences in the preparation of a vaccine for the protection of fish against infectious salmon anaemia virus. Specifically, such vaccines contain at least one nucleic acid sequence which is derived from ISAV or synthetically prepared analogues thereof, or substantially homologous sequences. These nucleic acid sequences are transcripted and translated into peptide sequences which are incorporated into a vaccination strategy to induce and immune response to the surface antigens of ISAV and therefore ISAV itself. Therefore both the use of a vaccine against ISAV, and the incorporation of peptide sequences is herein described.
1. A composition comprising an isolated and purified nucleic acid comprising the sequence of SEQ ID NO: 3.
2. A composition comprising an isolated and purified nucleic acid comprising a sequence encoding the amino acid sequence of SEQ ID NO: 4.
3. The composition according to claim 1 wherein said nucleic acid is incorporated in a plasmid.
4. The composition according to claim 3 wherein said plasmid is an expression vector.
5. An immunogenic composition comprising an expression vector wherein said expression vector further comprises a polynucleotide having the sequence of SEQ ID NO: 3.
6. An immunogenic composition comprising an expression vector wherein said expression vector further comprises a polynucleotide that encodes for a protein having the amino acid sequence of SEQ ID NO: 4.
7. A diagnostic kit comprising the composition of claim 1 .
8. A diagnostic kit comprising the composition of claim 2 .
9. A cell comprising the composition of claim 4 .
10. The composition according to claim 2 wherein said nucleic acid is incorporated in a plasmid.
11. The composition according to claim 10 wherein said plasmid is an expression vector.
12. A cell comprising the composition of claim 11 .
