[Experimental animal models in Mongolian gerbils and mice].
Helicobacter pylori is an emerging candidate agent for the genesis of chronic gastritis and peptic ulcer. There have been many challenges to establish an experimental infection with H. pylori in animals. In recent, several studies reported for animal infection with this organism. One of them was the study using urinary system. The study indicated the ability of H. pylori to induce inflammation without significant low pH condition. Experimental infection in Mongolian gerbils showed that H. pylori could colonize on the surface of the gastric mucosa in animals without human. The study of nude mice by Karita et al. showed several valuable facts concerning the relation between bacterial pathogenicity and potential of bacterial colonization in stomach. The study in which remaining of bacteria was extended showed that colonization of H. pylori was affected by bacterial flora in the stomach.
