Abstract
The invention relates to a chicken infectious coryza inactivated vaccine adjuvant. The adjuvant prepared in the invention is used as a chicken infectious coryza inactivated vaccine adjuvant to prepare a chicken infectious coryza inactivated vaccine and has the advantages of high antibody titer produced by inoculated chicken, long antibody protection period, high toxin expelling protection rate and the like.
Description
Technical field
The present invention relates to a kind of inactivated vaccine of infectious coryza of chicken adjuvant, belong to field of biology, particularly the veterinary biologics field.
Background technology
The popular rhinitis inactivated vaccine of existing market mainly contains two types, comprises oily adjuvant and aluminium glue Adjuvanted vaccines.The oil emulsion inactivated vaccine antibody persistent period is longer, but has side reaction in various degree.There is not the side reaction phenomenon in the aluminium glue adjuvant inactivated vaccine, but antibody titer is low, and the persistent period is short.
The inactivated vaccine of infectious coryza of chicken that novel adjuvant of the present invention is prepared from; Have safe, no side reaction, antibody and produce advantages such as fast and protective rate height; Not only be applicable to chicken crowd routine immunization; Effectively prevent the generation of eqpidemic disease, and be applicable to morbidity chicken crowd's urgent inoculation, to controlling primary disease and preventing that recurrence from having better action.
Summary of the invention
The purpose of this invention is to provide a kind of new adjuvant; The adjuvant that is applicable to inactivated vaccine of infectious coryza of chicken particularly is provided; Use it in the production process of inactivated vaccine of infectious coryza of chicken; Make the inactivated vaccine of infectious coryza of chicken of production have safe, no side reaction, antibody produces advantages such as fast and protective rate height, the urgent inoculation when both being suitable for normal prevention and also being suitable for falling ill, to the control primary disease with prevent that recurrence from having better action.
The specific embodiment
New adjuvant of the present invention is formulated by carbomer, potassium salt, sodium salt and deionized water.
New adjuvant of the present invention is used for the production process of inactivated vaccine of infectious coryza of chicken; Substitute traditional adjuvant; Can make the inactivated vaccine of infectious coryza of chicken of production have safe, no side reaction, antibody produces advantages such as fast and protective rate height, the urgent inoculation when both being suitable for normal prevention and also being suitable for falling ill.
One, adjuvant of the present invention
Novel adjuvant of the present invention, wherein carbomer is to contain the crosslinked acrylate copolymer of polyalkenyl polyether, (conventional amount used 0.25%～0.5%) just can produce thickening power efficiently under the very low consumption; Conventional amount used can substitute 3%～7% conventional emulsifier 0.2%～0.4%, can infectious coryza of chicken antigen parcel be adsorbed; After the inoculation; In the chicken body, can slowly discharge, can make antibody titer high, the duration is long.Na

Embodiment 3
1. vaccine safety is measured
8 of the subcutaneous healthy susceptible chickens with 2～3 monthly ages of chest muscle approach inoculation through cervical region of this vaccine, every subcutaneous injection vaccine 1ml observed 14, the no abnormal reaction of test chicken diet and health status, injection site dissection after putting to death, side reactions such as no granulation hyperplasia.
2. immune chicken serum detection of antibodies
Vaccine is through wing root muscle immunity 63 age in days SPF chickens; 0.5ml/ only, totally 8, different time sections blood sampling separation of serum after immunity respectively; Detect the Detection of antigen serum antibody with the Hpg-8 strain, the serum maximum dilution multiple that agglutination occurs with antigen-antibody 50% is decided to be the antibody titer of serum.
Immune chicken serum detection of antibodies result behind table 1 vaccine immunity
(data are to represent antibody valence with serum diluting multiple in the form).
Antibody growth and decline rule after the test chicken immunity; Immunity back 11d can produce protection antibody; Antibody titer reaches the peak during 31～40d; Begin progressively to descend from the later antibody of 40d, antibody valence occurs to 90d and be lower than 4 phenomenons, infer that according to " inactivated vaccine of infectious coryza of chicken rules " its protection period can reach 3 months.
3. the vaccine mensuration of immune duration of immunity once
This vaccine is inoculated 40 of the healthy susceptible chickens of 60 ages in days through chest muscle or leg muscle approach; Every vaccinate 0.5ml; Set up 20 of contrasts; 30d, 60d, 90d, 120d and 150d get 8 of immune group and 4 contrasts at random after immunity respectively, utilize the dilution of 350 times of C-Hpg-8 lyophilizing bacterial strains after under the socket of the eye hole inoculation 0.2ml/ only, the counteracting toxic substances result is following:
Table 2 vaccine is the mensuration of the immune duration of immunity once
According to the challenge test result, the interior protective rate of 90d reaches " inactivated vaccine of infectious coryza of chicken rules " standard behind this vaccine immunity, and matched group 4/4 is obviously fallen ill.
Through above result of the test is reached a conclusion: the inactivated vaccine of infectious coryza of chicken vaccine of novel adjuvant of the present invention preparation has safe, no side reaction, antibody produces soon and advantage such as protective rate height
