In the preparation process of cow mastitis vaccine, Gram-negative bacterium containing core universal antigen is utilized and transformed with genetic plasmid containing sucrose-6 fructose transferase. Under the induction of sucrose, Gram-negative bacterium suicides and the Gram-negative bacterium with core universal antigen is collected to prepare the cow mastitis vaccine. The said process produces no damage to immunogenicity of the vaccine and no substituted or non-natural vaccine antigen. Using non-toxic sucrose as chemical inducing matter can reduce the endotoxin in and side effect of the vaccine. The vaccine stimulates the immunological system to resist coibacillus, salmonella and other Gram-negative bacteria causing cow mastitis. |
