immunoglobulin Y (anti-Helicobacter pylori)

**Immunoglobulin Y anti-Helicobacter pylori** refers to an IgY-research program comprising orally administered, chicken egg-yolk-derived polyclonal IgY antibodies directed against *Helicobacter pylori*. The antibodies are generated by immunizing hens with *H. pylori* antigens and harvesting antigen-specific IgY from egg yolk. The intended mechanism is local neutralization of *H. pylori* in the gastrointestinal tract, including interference with bacterial virulence functions such as urease activity, thereby reducing colonization and infection burden. IgY-research has publicly described anti-*H. pylori* IgY work in human-health research materials, including dietary and functional-food studies; however, a distinct standardized pharmaceutical product, development code, formulation, and formal clinical phase are not publicly established.
