BACKGROUND Helicobacter species associated with human infection include Helicobacter pylori, Helicobacter heilmannii and Helicobacter felis among others. In this study we determined the prevalence of H. pylori and non-Helicobacter pylori organisms H. felis and H. heilmannii and analyzed the association between coinfection with these organisms and gastric pathology in patients presenting with dy...

BACKGROUND Previous international consensus statements provided general policies for the management of Helicobacter pylori infection. However, there are geographic differences in the prevalence and antimicrobial resistance of H. pylori, and in the availability of medications and endoscopy. Thus, nationwide or regional consensus statements are needed to improve control of H. pylori infection and...

The availability of clinic-based diagnostic tests means that screening for and the eradication of Helicobacter pylori can be done by primary care physicians. However, confusion still exists regarding indication and treatment regimens. It is universally accepted that patients with Helicobacter pylori infection and peptic ulcer disease require eradication therapy. But the benefits of Helicobacter...

Helicobacter pylori infection causes severe gastroduodenal diseases in humans. Its virulence is strongly increased by the presence of the cag pathogenicity island (cag PAI). It has been shown that CagA, a major antigen in humans, is translocated to the host cell via a secretion system encoded by the cag PAI. The roles of many of the proteins encoded within the cag PAI are not known. Here we rep...

Background Helicobacter pylori, responsible for one of the most frequent infections on the globe, was reported by several literature studies to be less frequent among patients infected with human immunodeficiency virus (HIV), especially at low levels of CD4+ T-cells. The purpose of the study was to evaluate the features of Helicobacter pylori infection in HIV-positive patients from the Mureş re...

Helicobacter pylori infection is a major cause of peptic ulcer disease, and its detection and eradication are now an important part of gastroenterology. Effective regimes are available which will eliminate the organism in about 90% of cases in developed countries.

Differences may occur in the mode of transmission of Helicobacter pylori between developed and developing countries: direct human-to-human contacts have been suggested as the primary route in the former while the fecal-oral route, also, through contaminated water, in the latter. Data on intrafamilial transmission of H. pylori among children continue to be produced. The importance of low socioec...
