Fowl adenovirus vaccine
Disclosed is a vaccine comprising fiber (2) protein of Fowl Adeno-virus C (FAdV-C) or an immunogenic fragment thereof for use in preventing hepatitis-hydropericardium Syndrome (HHS) in birds, preferably in poultry, especially in broilers.
1. A vaccine for use in preventing hepatitis-hydropericardium syndrome (HHS) in birds comprising fiber-2 protein of Fowl Adenovirus C (FAdV-C), wherein the vaccine is further defined as a subunit vaccine comprising an immuno-effective amount of an adjuvant.
2. The vaccine of claim 1 , wherein the adjuvant is Freund's complete adjuvant, Freund's incomplete adjuvant, aluminum hydroxide, Bordetella pertussis , saponin, muramyl dipeptide, ethylene vinyl acetate copolymer, oil, a vegetable oil or a mineral oil.
3. The vaccine of claim 2 , wherein the adjuvant is peanut oil or silicone oil.
4. The vaccine of claim 1 , wherein the fiber-2 protein of FAdV-C has a protein sequence of any one of SEQ ID NO: 9 through SEQ ID NO: 33.
5. The vaccine of claim 4 , wherein the sequence of the fiber-2 protein of FAdV-C is the protein sequence of SEQ ID NO: 23.
6. The vaccine of claim 1 , further comprising a pharmaceutically acceptable diluent and/or carrier.
7. The vaccine of claim 6 , wherein the pharmaceutically acceptable diluent and/or carrier comprises a water-for-injection, physiological saline, tissue culture medium, propylene glycol, polyethylene glycol, vegetable oil, or an injectable organic ester.
8. The vaccine of claim 1 , wherein the fiber-2 protein of FAdV-C is contained in an amount of 0.1 μg/ml to 10 mg/ml.
9. The vaccine of claim 8 , wherein the fiber-2 protein of FAdV-C is contained in an amount of 1 μg/ml to 1 mg/ml.
10. The vaccine of claim 9 , wherein the fiber-2 protein of FAdV-C is contained in an amount of 10 to 100 μg/ml.
11. The vaccine of claim 1 , consisting of:
fiber-2 protein of FAdV-C, in an amount of 0.1 μg to 10 mg; and
a pharmaceutically acceptable carrier and/or diluent and/or adjuvant.
12. The vaccine of claim 11 , wherein the fiber-2 protein of FAdV-C is in an amount of 1 μg to 1 mg.
13. The vaccine of claim 12 , wherein the fiber-2 protein of FAdV-C is in an amount of 10 to 100 μg.
14. A method for preventing HHS in birds, comprising administering to the birds a vaccine of claim 1 .
15. The method of claim 14 , wherein the birds are in a parent flock.
16. The method of claim 14 , wherein the birds are poultry.
17. The method of claim 16 , wherein the poultry are broilers.
18. A kit comprising an isolated fiber-2 protein of FAdV-C immobilized on a solid surface or an immunogenic fragment of a fiber-2 protein of FAdV-C immobilized on a solid surface.
19. The kit of claim 18 , further comprising a detection component that can detect the binding of an antibody to the immobilized fiber-2 protein of FAdV-C or the immobilized immunogenic fragment thereof.
