Helicobacter pilori

Helicobacter pylori - a spiral Gram-negative bacteria

Helicobacter pilori is a spiral shaped gram-negative bacterium that infects various areas of the stomach and duodenum. Helicobacter pylori infection often causes stomach ulcers and duodenal ulcers, gastritis, duodenitis. In the course of evolution, these microorganisms have acquired a spiral shape, which helps them to penetrate the lining of the stomach and duodenum.

The bacteria can live in the acidic environment of the stomach, although it was thought that microorganisms can not survive in such conditions. This is the cause of most diseases. The bacteria is able to destroy the cells of the stomach during the breeding season. In the long run, the release of negative substances, causes chronic inflammation and lead to gastritis.


Most infected carriers of Helicobacter pylori have no symptoms of the disease.


The bacteria was suspected of atrocities as gastritis, ulcers, and probably malignant tumors of the digestive tract. H. pylori were found on inflamed tissues more often than on healthy tissues.

In the U.S. there was a mass survey, which showed that almost all people suffering from peptic duodenal and 80% of patients with gastric ulcer were infected with Helicobacter pylori. In the stomach of healthy people bacteria can also be found.


Patients ,who have a gastric ulcer, gastritis or duodenal ulcer with evidence of H. pylori etiology, are appointed eradication of Helicobacter pylori. This treatment regime is aimed at the complete destruction of the microbe in the stomach for ulcer healing.

The treatment of Helicobacter pylori by itself is quite aggressive and not always easily portable for the human body. Based on the results of scientific research there have been developed international guidelines for the eradication of Helicobacter pylori and related diseases.

Doctors use the secretion blocker ,consisting of two antibiotics , for the treatment of Helicobacter pylori. It is used in standard doses for 7-14 days. The time of treatment and choice of antibiotics is carried out from characteristics of each case.
