Abstract

Development of the pathologies associated with Helicobacter pylori infection, most seriously gastric adenocarcinoma, are a consequence of chronic inflammation, which both host and pathogen go to some lengths to minimize. Recently, we presented evidence that H. pylori can suppress the development of inflammation in its immediate microenvironment in the gastric mucosa of 129/Sv mice. We have now extended this study by showing that H. felis, a gastric colonizing Helicobacter closely related to H. pylori, does not possess the same ability to suppress Helicobacter-induced gastritis in mice. Differences between these bacterial species may provide clues as to the mechanism behind the inflammation-r..
