Immunologically mediated protection against H. pylori infection is an attractive alternative to antibiotic treatment. We compared the efficacy of conventional protein vaccination with that of genetic vaccination against experimental infection with H. pylori in mice. For oral immunization, we used the recombinant peptide of an antigenic fragment of UreB (rUreB) or H. pyloriwhole cell lysate antigens, and for genetic immunization, we used recombinant pcDNA and pSec plasmids inserted with the fragment of ureB or DNA of the H. pylori genomic library. Mice were challenged with the mouse stomachadapted H. pylori Sidney Strain. The detection of gastric bacterial colonization was performed by real-time PCR of a 26-kDa Helicobacter-specific gene, and the presence of serum H. pylori-specific antibodies was determined using direct ELISA assay. The most effective treatment appeared to be oral vaccination with rUreB and either intramuscular or intradermal vaccination with DNA of the H. pylori genomic library. Intradermal genetic vaccination with genomic library DNA significantly increased the IgG antibody response. Our study revealed acceptable efficacies of genetic vaccination with DNA of the H. pylori genomic library.
