Problems solved by technology

[0005] The above-mentioned technical measures mainly achieve the purpose of improving immunity by improving the breeding environment of fish, shrimp, crab, and frog and adjusting their nutritional status. However, when fish, shrimp, crab, and frog have poor physical conditions, the traditional The anti-disease effect of immunomodulatory measures will be affected
There are also some immune enhancers that after long-term use, aquatic products are prone to drug resistance, so the present invention studies a Serratia marcescens immune enhancer for frog immunity according to the characteristics of Serratia marcescens

Abstract

The invention discloses a serratia marcescens immunoenhancer for frog immunization. The immunoenhancer comprises serratia marcescens agent, vitamin C, anthocyanin, citric acid, dihydrocapsaicin and glycerin, the serratia marcescens agent serves as a main ingredient and plays a role in enhancing frog immunity, and anthocyanin and dihydrocapsaicin are synergistic, so that immune effect can be improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a Serratia marcescens immune enhancer for frog immunity. Background technique [0002] Serratia marcescens (Serratia marcescens), also known as Bacteria, is a bright red pigment-producing bacterium that exists in air and water and can grow in animal and plant foods. It is the smallest among bacteria, about 0.5×(0.5~1.0) microns. Near spherical brevibacterium, but the shape is diverse. Serratia marcescens is widely distributed in nature. It is a resident flora in water and soil, and is also a common clinical opportunistic pathogen. It can cause lung and urinary tract infections and sepsis when the body's immune function is weakened. [0003] Chinese invention patent CN1465353A discloses a Serratia marcescens vaccine for treatment. The patent discloses the curative effect of the Serratia marcescens vaccine on some diseases closely related to immune function. Functions of cel...
