Determination of Helicobacter pylori virulence-associated genes in duodenal ulcer and gastric biopsies
Background: Helicobacter pylori (H. pylori or Hp) has been strongly associated with the peptic ulcer diseases, chronic gastritis, ulcers, and gastric cancer. Genes associated with pathogenicity have been designated for H. pylori, and some of them appear to be related to more severe clinical consequences of the infection. The present study was conducted to determine cagA, vacA, cagE, iceA1, oipA...
متن کاملvacA genotypes in Helicobacter pylori strains isolated from children with and without duodenal ulcer in Brazil.
Data concerning the association between vacA genotypes and disease in children in both developed and developing countries are scarce, especially because of the small number of children with a duodenal ulcer studied. The vacA genotypes of Helicobacter pylori strains obtained from 65 children (24 with a duodenal ulcer and 41 without a duodenal ulcer; 33 girls; mean age, 10.2 years; age range, 1 t...
متن کاملvacA genotypes in Helicobacter pylori strains isolated from patients with and without duodenal ulcer in Bahrain.
BACKGROUND The vacuolating cytotoxin and the cytotoxinassociated protein, encoded by vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori. OBJECTIVE The aim of this study was to perform vacA genotyping and evaluate its association with cagA genotype and clinical outcome. METHODS One hundred and twenty H. pylori strains were isolated from dyspeptic patient...
متن کاملHistological Changes In Gastric Biopsies From Helicobacter Pylori-Infected Patients With And Without Peptic Ulcer
Background and Objective: Long period risk of gastric carcinoma in people affected with chronic Helicobacter pylori gastritis is 5 times more than normal people. Perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. Materials and Methods: This study has been carried out as a cross...
متن کاملDifferences in surface-exposed antigen expression between Helicobacter pylori strains isolated from duodenal ulcer patients and from asymptomatic subjects.
We have analyzed possible qualitative and quantitative differences in antigen expression between Helicobacter pylori strains isolated from the antrum and different locations in the duodenum of 21 duodenal ulcer (DU) patients and 20 asymptomatic subjects (AS) by enzyme-linked immunosorbent assay (ELISA) and inhibition ELISA. Almost all antral and duodenal strains grown in vitro expressed the N-a...
