The Relationship of a Helicobacter heilmannii Infection to the Mucosal Changes in Abattoir and Laboratory Pig Stomach

Purpose A pig ulcer model in which ulceration is reproducibly induced in the pars oesophagea (a tongue of the oesophageal squamous epithelium that extends into the pig stomach) by bile duct ligation (BDL) was used in this study to determine whether Helicobacter heilmannii (Hh) is a predisposing factor in the ulceration of this region. The infection with Hh and its relationship to ulceration and mucus integrity was examined.
