Description
Technical field
The invention belongs to aquiculture disease immune protection technical field, and in particular to a kind of fresh water fish bacterial septicemia is exempted from
Epidemic disease prevents and treats bivalent inactivated vaccine and prepare with scale technology.
Background technology
The bacillary hemorrhage of freshwater fish is that harm cultured freshwater fish is the most serious also known as bacterium hueppe's disease
One of infectious disease, the fish of harm mainly have the fish such as grass, silver carp, flathead, crucian carp, carp, triangular bream, dace, eel, mandarin fish, are caused to freshwater aquaculture industry
Heavy losses (reach more than 30%).The cause of disease is mainly Aeromonas Aeromonas veronii) and Aeromonas hydrophila, he
The bacterial septicemia disease that causes account for more than 80%, be the most common pathogenic bacteria of freshwater fish.It is general using disinfectant and
Chemical drug antibiotic etc. carries out anti-treatment, easy polluted-water, and causes aquatic products medicament residue problem.Vaccine can stimulate dynamic fish body to produce
The attack of raw immune defense cause of disease, can also strengthen the ability of the anti-distress of body, as one of disease prevention and control measure.It is domestic near
Aquatic products vaccine development makes fast progress over 10 years, but vaccine large-scale preparation method more lacks, essentially laboratory preparation techniques,
At present in the urgent need to can industrialization production aquatic products production of vaccine technology.
The content of the invention
In order to solve problems of the prior art, gone out the invention provides a kind of Vickers, Aeromonas hydrophila bigeminy
Live vaccine and prepare with scale technology.
The present invention is realized by the following technical solutions:
