AORN Journal, 1997 Helicobacter pylori is a gram-negative bacterium which causes chronic gastritis and plays important roles in peptic ulcer disease, gastric carcinoma, and gastric lymphoma. H. pylori has been found in the stomachs of humans in all parts of the world. In developing countries, 70 to 90% of the population carries H. pylori.

Infectious Disease Clinics of North America, 1998 Helicobacter pylori infection causes peptic ulcer disease, gastric adenocarcinoma, gastric lymphoma, and probably nonulcer dyspepsia. Although the prevalence of infection is declining over time, the organism still infects approximately one half of the world's population. Only a minority will ever suffer serious consequences from their infection.

Epigenetics and Helicobacter pylori [PDF]
International Journal of Molecular Sciences, 2022 Epigenetics regulates gene expression, cell type development during differentiation, and the cell response to environmental stimuli. To survive, bacteria need to evade the host immune response. Bacteria, including Helicobacter pylori (Hp), reach this target epigenetically, altering the chromatin of the host cells, in addition to several more approaches,

Scandinavian Journal of Gastroenterology, 1991 Helicobacter pylori is a unique pathogen and the leading cause of chronic gastric inflammation. For many individuals the organism is of low virulence, causing only mild inflammation and generating few, if any, dyspeptic symptoms. For those with more severe inflammation, H. pylori infection may be causal in the generation of dyspeptic symptoms.
