Description
Technical Field
The invention relates to the technical field of production of vaccines for animals, in particular to a heat-resistant protective agent of a chicken newcastle disease and bronchitis bigeminal live vaccine and a preparation process thereof.
Background
The freeze-drying protective agent and the preparation process thereof are a key technology in the production of live vaccines, and have great influence on the storage, transportation and use of the vaccines. At present, in domestic veterinary vaccines, live freeze-dried vaccines account for a considerable proportion, and domestic commonly used protective agents mainly comprise milk, sucrose, gelatin and the like, and the live freeze-dried vaccines have simple formula and poor protective function on the vaccines. The vaccine freeze-dried by the traditional protective agent usually requires that the product is kept below-15 ℃, which causes great inconvenience to manufacturers and users, is limited in long-term storage and transportation of the vaccine, and may cause inactivation and efficacy reduction of the vaccine due to improper storage of the vaccine, so that the aim of epidemic prevention cannot be achieved, and huge economic loss is caused.
Compared with the conventional freeze-drying protective agent, the heat-resistant freeze-drying protective agent has the characteristic of long high-temperature-resistant storage period, so that the heat-resistant protective agent has better performance than the conventional protective agent, the live vaccine can be stored at 2-8 ℃ in the valid period, and can be stored for dozens of days even at higher room temperature, and the storage, transportation and use of the live vaccine are more convenient and economical.
The research on the heat-resistant protective agent in the developed countries starts earlier, and at present, the heat-resistant protective agent is basically used in the freeze-dried live vaccines of the developed countries, but the research is not reported in detail. The development of the domestic veterinary biological product protective agent is relatively lagged, and in recent years, China also has some related research reports, mainly including the research on heat-resistant freeze-drying protective agents for chicken newcastle disease, chicken Marek's disease, chicken bursa disease, chicken infectious bronchitis, chicken pox, swine fever freeze-drying live vaccines and the like. The research on the heat-resistant freeze-drying protective agent of the newcastle disease and infectious bronchitis combined live vaccine usually uses 5% sucrose skim milk as the protective agent, the performance of the product is not stable enough, and the passing yield is low.
Disclosure of Invention
In order to solve the problems, the invention provides a heat-resistant protective agent of a chicken newcastle disease and bronchitis bivalent live vaccine and a preparation process thereof.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a heat-resistant protective agent for chicken newcastle disease and bronchitis bigeminal live vaccine comprises solution A and solution B at a volume ratio of 4: 1; wherein the solution A consists of the following components: 20-30g of calcium lactate, 5-10g of thiourea, 15-20g of sucrose, 3-5g of trehalose, 5-10g of L-sodium glutamate and 10-20g of bovine serum albumin; supplementing water for injection to 800 ml; the solution B consists of the following components: 4-6g of polyvinylpyrrolidone and 3-5g of d-mannitol, and the volume is increased to 200mL by using water for injection.
Preferably, the solution A consists of the following components: 30g of calcium lactate, 10g of thiourea, 20g of sucrose, 4g of trehalose, 6g of L-sodium glutamate and 16g of bovine serum albumin; the injection water is supplemented to 800 ml.
Preferably, the liquid B consists of the following components: 5g of polyvinylpyrrolidone and 4g of d-mannitol, and the volume of the solution is made up to 200mL with water for injection.
A preparation process of a chicken Newcastle disease and bronchitis bivalent live vaccine heat-resistant protective agent comprises the following steps:
s1: firstly, heating 500ml of water for injection to boil, slowly adding calcium lactate, stirring until the calcium lactate is completely dissolved and transparent, and filtering by qualitative filter paper; dissolving thiourea, sucrose, trehalose, L-sodium glutamate and bovine serum albumin in calcium lactate solution in sequence, supplementing to 800ml with water for injection, and filtering for sterilization;
s2: heating 100mL of water for injection to boil, adding polyvinylpyrrolidone, adding d-mannitol, and stirring until the mixture is dissolved and transparent; the preparation of the solution B is completed by autoclaving under the condition of 15 pounds for 15 minutes and supplementing the solution to 200mL by using water for injection;
s3: mixing 800ml of the solution A and 200ml of the solution B, and storing for 1-2 weeks at normal temperature; when in use, the protective agent and the antigen of the newcastle disease and the infectious bronchitis virus are mixed according to the ratio of 1: mixing at a ratio of 1, packaging, and lyophilizing.
Preferably, the filter sterilization described in S1 is performed with a 0.22 μm microporous filter.
Preferably, the freeze-drying in S3 includes freezing, evacuating, and drying, wherein the freezing is performed at a low temperature of-40 ℃ for 480min, the frozen heat-resistant protective agent is then evacuated at a low temperature of-40 ℃ for 1min, the evacuation environment is maintained at a vacuum degree of 90ubar, and then the drying is performed for three times in a vacuum degree of 90ubar, the temperature for the first drying is-20 ℃, the time for the first drying is 2000min, the temperature for the second drying is 20 ℃, the time for the second drying is 300min, the temperature for the third drying is 25 ℃, and the time for the third drying is 1 min; and then the fourth drying is carried out under the vacuum degree of 50ubar, the temperature of the fourth drying is 25 ℃, and the time of the fourth drying is 300-.
The application of the heat-resistant protective agent for the Newcastle disease and bronchitis combined live vaccine is as follows: when in use, the protective agent is mixed with newcastle disease and infectious bronchitis virus antigen according to the proportion of 1: 1, subpackaged and freeze-dried.
Compared with the prior art, the invention has the beneficial effects that:
after the vaccine protected by the protective agent is placed in a 37 ℃ incubator for 10 days, virus content is measured according to a potency test chick embryo test method; compared with the virus content of effectiveness test, the virus content of each feather of Newcastle disease and infectious bronchitis of chicken is reduced by not more than 1 titer after 10 days, all the test results are qualified, the performance of the protective agent is stable, and the yield of the protective agent produced by the preparation process of the heat-resistant protective agent is high.
