In order to develop a safe and effective immunoadjuvant to enhance the immunity and resistance of animals against infection, a novel CpG Oligodeoxynucleotides containing 11 CpG motifs was synthesized and inserted into the VR1012 plasmid, designated as VR1C. Then the recombinant VR1C was entrapped with Chitosan nanoparticles prepared by the method of ionic cross linkage, and employed to inject muscularly 3-weeks old Kunming mice; the blank VR1012 packed with CNP and saline were used to inoculate mice as the control groups. 28 days after inoculation, all mice were orally fed with 0.4ml 2x108CFU/ per mouse virulent hemorrhagic enteritis E. coli to challenge the resistance against infection.
