Helicobacter pylori (H. pylori) is responsible for causing chronic gastritis, which can cause
peptic ulcer and premalignant lesions such as atrophic gastritis, intestinal metaplasia, and …

Background and aims Helicobacter pylori colonises the stomach in half of all humans, and is
the principal cause of gastric cancer, the second leading cause of cancer death worldwide …

Background The Helicobacter pylori (H. pylori) has evolved with its human host by nearly
110,000 years. Despite that H. pylori has been considered as a main factor for gastric cancer …

OBJECTIVES: The aim of this study was to compare the distribution of virulence-associated
genotypes of Helicobacter pylori in two Colombian populations with contrasting gastric …

Helicobacter pylori is the principal cause of gastric cancer, the second leading cause of
cancer mortality worldwide. However, H. pylori prevalence generally does not predict cancer …

Background: cagA‐positive and vacA s1 and m1 genotypes of Helicobacter pylori are
associated with an elevated risk of gastric cancer (GC). We determined these genotypes …

Helicobacter pylori (HP) genetics may determine its clinical outcomes. Despite high
prevalence of HP infection in Latin America (LA), there have been no phylogenetic studies in …

Helicobacter pylori (H. pylori) is a Gram-negative bacterium that infects half of the human
population. The infection is associated with chronic inflammation of the gastric mucosa and …

Helicobacter pylori is known as an important determinant of preneoplastic lesions or gastric
