Why do you post on this site? H. pylori is asociated with
"ulcers." Current theory suggests that "ulcers" are of
bacterial origin rather than "stress induced." This
web-site has nothing to offer to the H. Pylori dialogue.
If you are asking about an association between Dupuytrens
and H. Pylori bacteria, no one has raised the topic.
What, precisely are you asking? You may have a point;
I am only asking you to be more specific in you inquiry
that others might respond in a meaningful way.
Good luck!

What is Helicobacter pylori?

Helicobacter pylori (H. pylori) is a bacterium that causes chronic inflammation (gastritis) of the inner lining of the stomach in humans. This bacteria also is the most common cause of ulcers worldwide. H. pylori infection is most likely acquired by ingesting contaminated food and water and through person to person contact. In the United States, 30% of the adult population is infected. (50% of infected persons are infected by the age of 60.) The infection is more common in crowded living conditions with poor sanitation. In countries with poor sanitation, 90% of the adult population can be infected. Infected individuals usually carry the infection indefinitely unless they are treated with medications to eradicate the bacterium. One out of every six patients with H. pylori infection will develop ulcers of the duodenum or stomach. H. pylori also is associated with stomach cancer and a rare type of lymphocytic tumor of the stomach called MALT lymphoma.
