Effects of Anti-Helicobacter pylori IgY Powder to Protect Mice from Helicobacter pylori
2006
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.
