Keywords: Helicobacter pylori, infectious bacteria


Background and purpose: Helicobacter pylori is a type of bacteria that can cause infection in the stomach and duodenum and also cause digestive problems and diseases such as stomach ulcers, stomach infections, gastritis and in severe cases even stomach cancer. About 50% of the world's population is infected with this microbe, and the rate of infection is the same in men and women. In Iran, the prevalence rate in the age group over 45 years is 75.6 and in the 19-45 years age group is 68%.

Research method: This research is a review article and based on library study and literature review, which were studied by studying the articles published in domestic and foreign journals regarding the prevalence of Helicobacter pylori infection in patients. In order to access articles related to the subject of research from domestic and international databases such as IranMedex, IranDoc, Medline, Cochrane, Embase, SID, Medlib, Pubmed, Web of Sciences, Science Direct, Magiran without time limit until 1401 with The use of standard keywords were searched and then relevant information was extracted and evaluated.

Findings: In this review, 14 studies were examined and the findings show that Helicobacter pylori is the cause of most cases of stomach ulcers and causes the occurrence of some gastrointestinal cancers and is the most important cause of stomach cancer and MALT lymphoma. is also considered.

Conclusion: According to the results, stomach biopsy culture and determination of antibiotic sensitivity of bacteria have been proposed as the best treatment method for stomach microbe infection. Considering the complications caused by long-term and chronic Helicobacter pylori infection in people who have a history of stomach cancer in their family members, the infection of this bacterium is very dangerous and it is necessary to completely eradicate it in these people, and this issue is only through tissue sample culture Stomach can be done.
