Circovirus sequences associated with piglet weight loss disease (PWD)
View Patent ↗The genome sequences and the nucleotide sequences coding for the PWD circovirus polypeptides, such as the circovirus structural and non-structural polypeptides, vectors including the sequences, and cells and animals transformed by the vectors are provided. Methods for detecting the nucleic acids or polypeptides, and kits for diagnosing infection by a PWD circovirus, also are provided. Method for selecting compounds capable of modulating the viral infection are further provided. Pharmaceutical, including vaccine, compositions for preventing and/or treating viral infections caused by PWD circovirus and the use of vectors for preventing and/or treating diseases also are provided.
1. A vaccine comprising a first nucleic acid having a first nucleotide sequence with at least 90% sequence identity to SEQ ID NO:25 and a second nucleic acid having a second nucleotide sequence with at least 90% sequence identity to SEQ ID NO:27, and an acceptable pharmaceutical or veterinarily acceptable vehicle, wherein said first nucleic acid encodes an immunogenic protein that induces a protective response effective against infection by a piglet weight loss disease circovirus.
2. A vaccine comprising a first nucleic acid having a first nucleotide sequence with at least 90% sequence identity to SEQ ID NO:25 and a second nucleic acid having a second nucleotide sequence with at least 95% sequence identity to SEQ ID NO:27, and an acceptable pharmaceutical or veterinarily acceptable vehicle, wherein said first nucleic acid encodes an immunogenic protein that induces a protective response effective against infection by a piglet weight loss disease circovirus.
3. A vaccine comprising a first nucleic acid having a first nucleotide sequence with at least 95% sequence identity to SEQ ID NO:25 and a second nucleic acid having a second nucleotide sequence with at least 90% sequence identity to SEQ ID NO:27, and an acceptable pharmaceutical or veterinarily acceptable vehicle, wherein said first nucleic acid encodes an immunogenic protein that induces a protective response effective against infection by a piglet weight loss disease circovirus.
4. A vaccine comprising a first nucleic acid having a first nucleotide sequence with at least 95% sequence identity to SEQ ID NO:25 and a second nucleic acid having a second nucleotide sequence with at least 95% sequence identity to SEQ ID NO:27, and an acceptable pharmaceutical or veterinarily acceptable vehicle, wherein said first nucleic acid encodes an immunogenic protein that induces a protective response effective against infection by a piglet weight loss disease circovirus.
5. The vaccine of claim 1 , claim 2 , claim 3 , or claim 4 , wherein said first nucleotide sequence is SEQ ID NO:25.
6. The vaccine of claim 1 , claim 2 , claim 3 , or claim 4 , wherein said second nucleotide sequence is SEQ ID NO:27.
7. The vaccine of claim 1 , claim 2 , claim 3 , or claim 4 , further comprising an adjuvant.
8. A method of immunizing a mammal against piglet weight loss disease comprising administering to a mammal an effective amount of the vaccine of claim 1 , claim 2 , claim 3 , or claim 4 .
9. The method according to claim 8 , further comprising an adjuvant.
