Helicobacter pylori infection remains one of the most prevalent infections worldwide, causing significant morbidity and mortality from gastric malignancies and peptic ulcers. This article provides a summary of the microbiology and pathogenesis of this bacterium, emphasizing the complex and protean effects of H pylori on gastric epithelial cells, including stem and progenitor populations, and evasion of host immune defenses. Increasing antibiotic resistance has made management more challenging. This article discusses the appropriate diagnostic modality for different clinical scenarios, and the evolving treatment of H pylori infections, including the use of antibiotic susceptibility testing to aid regimen selection.

Outer membrane vesicles (OMVs) and exosomes are essential mediators of host-pathogen interactions. Elucidating their mechanisms of action offers valuable insights into diagnosing and treating infectious diseases and cancers. However, the specific interactions of () with host cells via OMVs and exosomes in modulating host immune responses have not been thoroughly investigated.

Aims: , the dominating cause of gastric cancer, most often infects children initiating inflammation in the antral part and spreads orally to the oxyntic mucosa. Traditionally, eradication of has been based upon a combination of antibiotics together with a proton pump inhibitor (PPI) to reduce gastric destruction of the antibiotics. Recently it has been shown that the more efficient inhibitors of acid secretion, the potassium-competitive acid blockers (PCABs) in combination with amoxicillin alone gave highly sufficient eradication.
