    摘要: Transgenic non-human animals are described which serve as a model for H. pylori infection of epithelial cells of the stomach and small intestine. The gut epithelial cells of the transgenic animals express one or more surface carbohydrate antigens which act as receptors for the bacterium H. pylori, a known causative agent of acid peptic disease, such as gastritis, stomach ulcers, duodenal ulcers, and strongly correlated with the development of gastric neoplasia. Methods for making and using the transgenic animals are also disclosed. The transgenic animals can be used to screen for compounds and conditions which block binding of H. pylori to the gut epithelium and/or ameliorate the H. pylori-associated pathogenesis of acid peptic disease and gastric adenocarcinoma.
