[Prevalence and routes of transmission of pyloric Helicobacter infection. II. Transmission infection from an external source (literature review)].

AIM OF THE STUDY: On the available reports to assess the possibility of the infection with pyloric Helicobacter (H.pylori) from external sources--via contaminated food and water. BASIC CONCEPTS: H. pylori was established to be unable to multiply in dairy and other products, but under favorable conditions, can survive in the limited time. There are obtained epidemiological data about the feedback between the prevalence of H. pylori infection in the region and the availability of safe water. There was recorded ability of bacteria to survive for a short time in water in bacillary virulent form. In different water sources in different countries there was found H. pylori coccal form.

CONCLUSION: H. pylori ability to survive in the commonly used product supports the hypothesis that contaminated food (tank-human) may serve as a conductor of infection. The literature data testify to the possibility and importance of the waterway for H. pylori infection transmission that changes the approaches to prophylaxis and the prevention of associated with it diseases.
