Helicobacter pylori is a gram-negative microaerophilic bacterium that infects the epithelial lining of the stomach. Infection with this pathogen remains one of the most widespread chronic bacterial infections affecting humans worldwide. Inflammation of the gastric epithelium associated with mucosal damage is defined as gastritis. Approximately half the global population is believed to be infected with H pylori, although prevalence varies geographically. Risk factors for acquiring H pylori infection include low socioeconomic status, increasing number of siblings, and having an infected parent — particularly an infected mother.

Effective treatment of H pylori is necessary to avoid potential unwanted sequelae, such as gastric cancer. For many H pylori–associated conditions, such as gastritis, the most effective clinical intervention is to eradicate the infection. However, this is becoming increasingly challenging with the emergence of antibiotic-resistant H pylori strains.
