  • Lactic acid producing bacteria were isolated from baby feces and characterized to be used as a probiotic with anti Helicobacter pylori functions. The selected bacteria had inhibition activity on the adherance and growth of H. pylori. These bacteria had additional beneficial characteristics for the probiotic such as antibacterial activity, antitumor activity, immunostimulation activity, resistance to antibiotic and bile salt, ability to bind to the intestinal cells, and safe for the human use.

  • Effects of anti-Helicobacter pylori IgY powder on H. pylori infection were evaluated 3 and 7 weeks after powder feeding by urease, PCR, and histological tests, and specific IgG assay of murine gastric tissue using mouse model. To produce anti-H. pylori IgY powder, laying hens were immunized with H. pylori prior to egg yolk harvest. C57BL/6 mice showing high response to H. pylori were infected with H. pylori and fed with the anti-H. pylori IgY powder. In urease and PCR tests, urease activity and gene count of anti-H. pylori IgY powder-fed group significantly decreased in comparison with control. Histological results indicated anti-H. pylori IgY powder effectively protected mice from H. pylori.
