Abstract: This invention relates to a Helicobacter pylori adhesion inhibitor that is capable of eliminating Helicobacter pylori associated with the development of peptic ulcer from the stomach, a method for producing the same, and pharmaceutical compositions and foods for preventing or treating diseases associated with Helicobacter pylori comprising such Helicobacter pylori adhesion inhibitor. The inhibitor of the present invention has excellent activity of eradicating Helicobacter pylori and is highly safe. Accordingly, pharmaceutical compositions and foods comprising the same are highly useful for the prevention or treatment of the aforementioned diseases.

Abstract: An inhibitor of Helicobacter pylori colonization in the stomach comprises as an active ingredient a glycoprotein which specifically binds to H. pylori urease. This glycoprotein is isolated and purified from a glycoprotein-containing substance, especially that derived from bovine milk whey or albumen of chicken eggs by affinity chromatography using a column on which H. pylori urease is immobilized. The glycoprotein is able to effectively inhibit H. pylori colonization, so is useful for the prevention or treatment of diseases caused by infection of H. pylori such as peptic ulcers. A food and medicament comprising the inhibitor are also provided.

Abstract: An inhibitor composition of Helicobacter pylori adhesion in the stomach comprises (1) anti-urease antibodies obtained from eggs laid by hens which have been immunized against H. pylori urease and (2) an inhibitor of gastric acid secretion. This inhibitor is capable of completely eliminating H. pylori from the stomach, so it is useful for the prevention or treatment of diseases caused by infection of H. pylori such as peptic ulcers.

Abstract: The present invention provides specific antibodies obtained from eggs laid by hens which have been immunized against urease of Helicobacter pylori as an antigen, and specific antibodies obtained from eggs laid by hens which have been immunized against flagella of Helicobacter pylori as an antigen. These antibodies are useful for the prevention or treatment of gastritis, gastric ulcers and duodenal ulcers caused by infection of Helicobacter pylori. At least one organism selected from lactic acid bacteria, Enterococcuses, yeasts, and Baillus can be used along with the antibodies.

Abstract: The present invention provides a safe and effective inhibitor of Helicobacter pylori colonization in the stomach and a food containing the inhibitor. The inhibitor of the present invention comprises as an active ingredient a mucin, especially a mucin from milk of a cow or a mucin from albumen of an egg and is useful for the prevention or treatment of diseases caused by infection of Helicobacter pylori such as peptic ulcers.

Abstract: A hairless mouse designated NS:Hr/ICR is sensitive to H. pylori. This NS:Hr/ICR hairless mouse can be easily infected with H. pylori in its alimentary canal, and is therefore useful as an experimental animal model for H. pylori infection.

Abstract: A vaccine useful for the protection of poultry from colibacillosis infections which comprises as an active ingredient pre-inactivated and ultrasonicated E. coli cells, and a method for protecting poultry from colibacillosis infections which comprises inoculating said vaccine into poultry through cloaca.
