Helicobacter pylori cagA Status, vacA Subtypes and Histopathologic Findings in Iranian Patients with chronic gastritis
Background and Objective: Helicobacter pylori has several strains with different degrees of virulence. The aim of this study was to detect two major important virulence factors, cagA/vacA genotypes, and to determine correlations among different cagA/vacA genotypes and histological features of chronic gastritis in Iranian patients. Methods: In this cross- sectional study, Gastric bi...
متن کاملPrevalence of Pathogenic Genes cagA and vacA of Helicobacter pylori Isolated in Patients with Digestive Disorders
Background and Aims: Helicobacter pylori is the main cause of various gastroduodenal diseases. It is estimated that app roximately, more than half of the adult population in developed countries and 90% of people in developing countries infected with H. pylori. H. pylori infection may be related to Genetic of virulence factors and environmental factors. The aim of this study was to assess of fre...
متن کاملvacA s1m1 genotype and cagA EPIYA-ABC pattern are predominant among Helicobacter pylori strains isolated from Mexican patients with chronic gastritis
PURPOSE Virulent genotypes of Helicobacter pylori vacA s1m1/cagA+/babA2+ have been associated with severe gastric diseases. VacA, CagA and BabA are polymorphic proteins, and their association with the disease is allele-dependent. The aims of this work were: (i) to determine the prevalence of H. pylori by type of chronic gastritis; (ii) to describe the frequency of cagA, babA2 and vacA genotypes...
متن کاملPrevalence of cagA, vacA, babA2 and iceA genes in H. pylori strains isolated from Colombian patients with functional dyspepsia.
The clinical outcome of Helicobacter pylori infection has been particularly associated with virulence genotypes. These genotypes are useful as molecular markers in the identification of patients that are infected and at high risk for developing more severe gastric pathologies. Our main objective was to determine the prevalence of virulence genotypes cagA, vacA, iceA and babA2 of H. pylori, in p...
متن کاملVacA and cagA genotypes of Helicobacter pylori isolated from raw meat in Isfahan province, Iran
Foods with animal origins play a substantial role in the transmission of Helicobacter pylori. The present investigation was carried out to study the vacA and cagA genotypes status of H. pylori isolated from various types of meat samples. Two hundred and twenty meat samples were collected and cultured. H. pylori-positive strains were analyzed for the ...
