| Abstract: | The oral microencapsulated vaccine of Escherichia coli was prepared using a reforming technique of spray drying and boundary coordination. The average diameter of microencapsulated vaccine particles was 10μm and the package rate was 65%. The in vitro experiment showed that this vaccine could avoid destroying gastric acid and had good characteristics of intestines dissolve. The data from the lymph cell transformation test, plate agglutination test and ELISA test indicated that microencapsulated vaccine could effectively activate cell immunity,humoral immunity and mucous immunity and produce considerable IgA,IgG. In conclusion,this vaccine proved to be a safe,convenient and effective oral vaccine. |
