Abstract

The invention relates to an in-vitro preparation method of transfer factors capable of resisting duck viral hepatitis. In the method, the transfer factors capable of resisting the duck viral hepatitis are prepared through the induction of duck hepatitis virus by utilizing an in-vitro lymphocyte cell culture method; and chicken spleen or peripheral blood is used as a basic raw material to prepare single-layer lymphocyte cells, and then the single-layer lymphocyte cells are induced and cultured through phytohemagglutinin and the duck hepatitis virus, so that a large number of specific transfer factors capable of resisting the duck hepatitis virus are generated in vitro.. The transfer factors can effectively inhibit the virus of duck viral hepatitis, so that the normal bodies cannot be infected with the duck viral hepatitis, and the radical pre-prevention action can be realized. The method provided by the invention has the characteristics of being simple and easy to operate and the like.

Description

technical field

[0001] The invention relates to a preparation method of in vitro anti-duck viral hepatitis transfer factor, which belongs to the field of immunology. Background technique

[0002] Duck viral hepatitis is an acute and highly fatal infectious disease of ducklings caused by duck hepatitis virus (DVH). This disease is characterized by acute onset, short course of disease, rapid infection, and high morbidity and mortality. , causing significant economic losses to the farming industry.

[0003] Transfer factor (TF, Transfer Factor), also known as transfer factor, can be used as a cellular immunity enhancer. It is a low-molecular-weight polypeptide-nucleotide complex released by T lymphocytes that can transfer sensitization information. A certain specific cellular immune function is specifically transferred to the recipient's normal lymphocytes, participates in the body's immune response, and improves the recipient's cellular immune function; at the same time, it p...
