Abstract

The invention provides an application of a nocardia immunopotentiator in a fish vaccine, the nocardia immunopotentiator comprises nocardia, pachymaran and hyaluronic acid, and the invention also provides an application of the nocardia immunopotentiator in an oil emulsion inactivated vaccine for fish. According to the fish oil emulsion inactivated vaccine, vaccines aiming at different viruses or bacteria can be obtained according to different selected antigens; animal experiments prove that the nocardia immunopotentiator and the application thereof in fish vaccines enable the fish vaccines to be strong in immunity, and the oil emulsion vaccine added with the nocardia adjuvant has the advantages of high safety, no obvious residue in local vaccine injection, simple preparation process and wide application range, Tand the corresponding vaccine specificity is high.

Description

technical field [0001] The invention belongs to the technical field of medicine and biology, and in particular relates to the application of a Nocardia immune enhancer in fish vaccines. Background technique [0002] Immunopotentiators refer to substances that can enhance the body’s immune response either alone or simultaneously with antigens. There are many varieties of adjuvants, which can be divided into three categories according to their prerequisites: (1) Immune substitutes, used to replace certain Drugs with biological factors that enhance immunity; (2) immune recovery agents, which can enhance the suppressed immune function, but have little effect on normal immune function; (3) immune adjuvants, also known as non-specific stimulators. Commonly used immune enhancers include BCG, Corynebacterium pumilus, endotoxin, immune ribonucleic acid, thymosin, transfer factor, double-stranded polynucleotide, aluminum hydroxide adjuvant and so on. [0003] Although some of the abo...
