Immune Effects Of Four Different Adjuvants On Aeromonas Veronii Inactivated Vaccines

In recent years,the reports on the aquatic organisms of viven-monocyte infection are not uncommon,which has caused great economic losses to aquaculture.Nowadays,most of the diseases caused by the bacteria are selected for the prevention or treatment of chemical drugs.In contrast,the bacterial inactivated vaccines are green,safe,easy to operate and low in cost.The combination of inactivated vaccine and adjuvant comatibility are beneficial to the continuous production of specific antibodies and enhance the ability of aquatic animals to resist the invasion of foreign pathogens.In view of the domestic research on Vivtorinox Aeromonas inactivated vaccine is not yet mature,this research will have vickers gas identification made inactivated bacterium,and extract the flaAl（OH）3lum protein,at the same time,choose the aluminum hydroxide Al（OH）3,Glucan and APSs as immune adjuvant,set up the aluminum adhesive adjuvants for adjuvant control group,the other three kinds of adjuvants sets up three different concentration gradient respectively,points after compatibility with inactivated vaccine immune crucian carp,select the most suitable adjuvants and concentrationAt first,to explore microbial inactivated conditions,determine the 0.1%formaldehyde,role under 4℃for 12 h for optimum condition of inactivated.Then we extracted the flaA protein of vickers,and used SDS-PAGE electrophoresis to detect the bands and calibrate the concentration.Set up with flaAl（OH）3la protein 30%,30%,40%respectively,with APSs were 30%,40%,50%,containing Glucan were 30%,40%,30%,different concentrations of inactivated vaccine group,at the same time set up a blank control group,a no adjuvant inactivated vaccine group and a rubber aluminium adjuvant control group.After the observation of air conditioning,the 7th day of feeding,the 21st day,the 35th day of the intraperitoneal injection of immune crucian carp,in the two days after immunization,randomly selected carp for blood collection and collection.Some of the blood was prepared by anticoagulant in the preparation of anticoagulant for leukocyte phagocytosis,and the rest were prepared into serum for serum index detection.Found that all of the experimental group can create high levels of IgM antibody in serum levels,at the same time,the ACP and AKP in serum and SOD activity,LZM is on the rise,take heart,liver,spleen and kidney tissue,after extracting RNA by fluorescence quantitative PCR technology,detect IL-10 in different organizations,IL-1 beta,IFN-gamma and TNF alpha gene transcription,confirmed the adjuvant add can promote the body’s inflammatory response.In addition,the expression of il-10,il-1,IFN-and tnf-alpha in the experimental group was up-regulated,indicating that the addition of adjuvant could enhance the immune response level of carp.Through the calculation of leukocyte phagocytic experiment and immune protection rate,the enhancement ability of the experimental group on the immunity of crucian carp was further verified.Finally,summarized the flaAl（OH）₃lum 50%protein content of adjuvant crucian carp overall immune ability,the strongest 30%content of APSs adjuvants crucian carp immunity slightly times,40%Glucan adjuvants and aluminum plastic adjuvants are up and down each other on the indicator reaction,difficult to close,but slightly lower than the former two.
