Abstract Background Nearly all Taiwanese H. pylori stains are cagA-genopositive and
encode CagA protein. In this study, we evaluated whether different intensity of tyrosine …

Aim To detect the prevalence of the cagA, vacA, ureC and iceA genotypes of H. pylori from
antral biopsy specimens of patients and to associate its role in specific disease. Materials …

Introduction Helicobacter pylori infection is associated with gastro-duodenal diseases.
Genes related to pathogenicity have been described for H. pylori and some of them appear …

BACKGROUND AND AIMS: Helicobacter pylori iceA1 and iceA2 gene amplification is
usually performed to identify mixed populations as both genes are apparently reportedly …

Simple Summary Virulence factor genes in Helicobacter pylori (H. pylori) strains promote
changes in the gastric epithelial mucosa that are associated with the risk of developing …

Genotypic differences in Helicobacter pylori play an important role in infection. We
characterized the diversity of the cagA, cagE, babA2, and vacA genes in H. pylori strains …

Background Helicobacter pylori (H. pylori) is the main risk factor for the development of
chronic gastritis, gastric ulcer, and gastric cancer. In H. pylori-infected individuals, the clinical …

Introducción y objetivo La gastritis folicular se asocia con la infección por Helicobacter
pylori; sin embargo, su relación con los genotipos bacterianos es poco conocida. Nuestro …

Purpose. Virulent genotypes of Helicobacter pylori vacA s1m1/cagA+/babA2+ have been
associated with severe gastric diseases. VacA, CagA and BabA are polymorphic proteins …
