Abstract
The invention discloses a heat-resisting lyophilized protectant for chicken newcastle disease and chicken infectious bronchitis dual living vaccine and a preparation method thereof. The heat-resisting protectant consists of solution A and solution B in a volume ratio of 1:1, wherein the solution A consists of the following compositions: 4 to 6g of sucrose, 3 to 5g of polypeptone, 1 to 3 g of D-sorbitol and the balance of water for injection in each 100 milliliters of the solution A; and the solution B consists of the following compositions: 3 to 5g of polyvinylpyrrolidone, 0.5 to 1.5g of L-arginine and the balance of water for injection in each 100 milliliters of the solution B. The heat-resisting lyophilized protectant has the advantages of good heat resistance, capacity of effectively protecting the living vaccine, simple formula components and preparation method, low production cost, and mass production and the like. The heat-resisting lyophilized protectant can ensure that the chicken newcastle disease and chicken infectious bronchitis dual living vaccine is preserved for more than 24 months at a temperature of between 2 and 8 DEG C.
Description
Technical field
The present invention relates to a kind of protective agent of viral lived vaccine, relate in particular to heat-resisting lyophilized protecting agent of newcastle disease and infectious bronchitis of chicken bigeminal live vaccine and preparation method thereof, belong to animal and make the field with viral lived vaccine.
Background technology
Freeze drying protectant and preparation technology thereof are key technologies during live vaccine is produced, and preservation, transportation and the use of vaccine had a significant impact.At present, in China's live vaccine, the freeze dried vaccine of living accounts for sizable ratio, and domestic protective agent commonly used is mainly milk, sucrose, gelatin etc., and its prescription is simple, and is poor to the defencive function of vaccine.Adopt the freeze dried vaccine of these traditional protective agents; owing to need be kept at the low temperature below-15 ℃; this puts to no little inconvenience to manufacturer and user; make the long preservation and the transportation of finished product vaccine limited; and may be because vaccine is preserved the improper vaccine inactivation that causes; render a service and reduce, do not reach the epidemic prevention purpose, cause the tremendous economic loss.
Heat-resisting lyophilized protecting agent is compared with the freeze drying protectant of routine; its freeze dried vaccine has the characteristics of high temperature resistant long shelf-life; thereby the performance of heat resisting protective is more better than traditional protection agent; live vaccine can be kept under 2~8 ℃ of conditions before the deadline; even under higher room temperature, also can preserve tens days, therefore make storage, transportation and the use of live vaccine all more convenient, economical.
The defencive function of freeze drying protectant mainly has very big relation with the factor of two aspects.The one, microbiological factor, the kind of microorganism has determined that with aspects such as itself architectural difference (having or not cyst membrane as virus), cultural method and vaccine kinds protectant prescription of variety classes vaccine also should be different; The 2nd, protectant prescription factor is as protective agent raw material and character thereof, proportioning, freeze-drying curve.The prescription of heat-resisting lyophilized protecting agent will be selected prescription according to above the two principal element, and is reasonably combined, and checking repeatedly, formulates rational freeze-drying curve.After the product lyophilizing, its physical behavior is carried out storage life test, and sample is placed on contrast tests such as carrying out storage life length and titration, safety examination under the different temperatures.According to result of the test, constantly adjust prescription and freeze-drying curve, to reach ideal effect.
The eighties in 20th century, developed country just begins to carry out the research of heat resisting protective, and their freeze-dried live vaccine uses heat resisting protective basically at present, but does not see play-by-play.The protectant development of domestic veterinary biologics relatively lags behind; in recent years also there is the research report of some this respects in China; mainly comprise the heat-resisting lyophilized protecting agent research of newcastle (ND), IBD, MD, IBV, fowlpox and swine fever freeze-dried live vaccine etc.; but do not reach the level of applying yet, at present the domestic report of not seeing newcastle disease, infectious bronchitis of chicken bigeminal live vaccine heat-resisting lyophilized protecting agent as yet.
Problems such as in a word, it is complicated how existing heat-resisting lyophilized protecting agent exists prescription to some extent, is not easy to operation, and protective value is undesirable.Develop that a kind of compound method is simple, cost is low, can large-scale production, the newcastle disease with good protection performance, infectious bronchitis of chicken bigeminal live vaccine heat-resisting lyophilized protecting agent just seem particularly urgently important.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide that a kind of compound method is simple, cost is low, can large-scale production, the newcastle disease with good protection performance and infectious bronchitis of chicken bigeminal live vaccine heat-resisting lyophilized protecting agent.
Technical problem to be solved by this invention realizes by following technological approaches:
