Abstract
The invention discloses a duck adenovirus type-3 virus strain and preparation and application of a yolk antibody thereof, wherein the duck adenovirus type-3 yolk antibody prepared by the invention is prepared from a duck adenovirus type-3 virus strain with a preservation number of CCTCC NO: the virus strain of the invention is produced by immunizing poultry with the GD06 strain of duck adenovirus type 3 virus of V201905, and has good specificity and immunogenicity; the duck adenovirus type 3 egg yolk antibody has high safety, high immune protection rate and wide application prospect, effectively prevents the infection of the duck adenovirus type 3, effectively treats the duck adenovirus type 3, can be used for detecting the duck adenovirus type 3 virus and has wide application prospect.
Description
Technical Field
The invention belongs to the field of animal antigen antibodies, and particularly relates to a duck adenovirus type 3 virus strain and preparation and application of a yolk antibody thereof.
Background
Adenovirus (Fowl adenovirus) is a common infectious disease of poultry and wild birds. In recent years, duck adenovirus type 3 (DAdV-3) is widely spread in China, and after duck adenovirus type 3 is infected, muscovy ducks have symptoms of liver swelling, pallor, spleen swelling, blood stasis and the like. The death rate of the disease can reach more than 50 percent, and huge loss is caused to the duck breeding industry. In recent years, the duck adenovirus type 3 prevalence has an outbreak trend, and the development of the duck breeding industry is seriously damaged.
At present, no effective prevention and control means is available for duck adenovirus type 3, but inactivated vaccines are reported, but the vaccines are still in the scientific research stage, and no successful report and produced products are available. Meanwhile, the existing research has the following problems: firstly, the disease infection model is unreasonable in design, typical symptoms do not appear after the duck is infected with viruses, no viruses are detected in all tissues, and the duck does not have death symptoms and is different from clinical data; secondly, after the duck is inoculated with the inactivated vaccine, effective antibodies can not be generated in a short period, and even if the antibodies are generated in a short period, the protection rate of the duck against viruses is low, so that the duck is not suitable for the ducks within 2 weeks.
At present, no effective duck adenovirus type 3 animal infection model exists, no prevention and treatment means aiming at the duck adenovirus type 3 exist, and a new duck adenovirus type 3 strain serving as an animal evaluation model and a safe and effective yolk antibody generated by the strain are urgently needed.
Disclosure of Invention
The invention aims to provide a duck adenovirus type-3 GD06 virus strain and preparation and application of a yolk antibody thereof.
The invention provides a duck adenovirus 3 type GD06 strain, which is preserved in China center for type culture Collection in 2019, 1 month and 31 days, and the preservation number is CCTCC NO: and V201905.
The technical scheme adopted by the invention is as follows:
