“…To our knowledge there is only a single report of H. pylori being successfully cultured from water, but this involved wastewater and as such may well represent fecal contamination of the water source (378). Spread via fecal contaminants is supported by the occurrence of H. pylori infections among institutionalized young people during outbreaks of gastroenteritis (350). Other possible sources include contaminated food, as H. pylori may survive briefly on refrigerated food (508).…”

SUMMARY Helicobacter pylori is the first formally recognized bacterial carcinogen and is one of the most successful human pathogens, as over half of the world's population is colonized with this gram-negative bacterium. Unless treated, colonization usually persists lifelong. H. pylori infection represents a key factor in the etiology of various gastrointestinal diseases, ranging from chronic active gastritis without clinical symptoms to peptic ulceration, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Disease outcome is the result of the complex interplay between the host and the bacterium. Host immune gene polymorphisms and gastric acid secretion largely determine the bacterium's ability to colonize a specific gastric niche. Bacterial virulence factors such as the cytotoxin-associated gene pathogenicity island-encoded protein CagA and the vacuolating cytotoxin VacA aid in this colonization of the gastric mucosa and subsequently seem to modulate the host's immune system. This review focuses on the microbiological, clinical, immunological, and biochemical aspects of the pathogenesis of H. pylori.

“…A recent study from France showed an association between gastroenteritis and subsequent acquisition of H. pylori infection in institutionalized children and adolescents with neurologic deficit, but it was not clear whether this was due to feco‐oral (diarrhea) or oro‐oral (vomitus) transmission [22].…”

“…Vomit has an especially high bacterial density [21]. H. pylori transmission to persons in contact with the patient was observed after breakouts of acute gastrointestinal infections [22]. Close contact with H. pylori contaminated body secretions within the families explains the increased incidence of infections within the family (see I.…”

This guideline updates a prior consensus recommendation of the German Society for Digestive and Metabolic Diseases (DGVS) from 1996. It was developed by an interdisciplinary cooperation with representatives of the German Society for Hygiene and Microbiology, the Society for Pediatric Gastroenterology and Nutrition (GPGE), and the German Society for Rheumatology. The guideline is methodologically based on recommendations of the Association of the Scientific Medical Societies in Germany (AWMF) for providing a systematic evidence-based S 3 level consensus guideline and has also implemented grading criteria according to the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) process. Clinical applicability of study results as well as specifics for Germany in terms of epidemiology, antibiotic resistance status, diagnostics, and therapy were taken into account.
