Role of dupA in virulence of Helicobacter pylori
Helicobacter pylori (H. pylori) is a gastric human pathogen associated with acute and chronic gastritis, 70% of all gastric ulcers, 85% of all duodenal ulcers, and both forms of stomach cancer, mucosal-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma. Recently, attention has focused on possible relationship between presence of certain virulence factor and H. pylori-associated disea...

متن کاملHelicobacter pylori: Determinant and Markers of Virulence
In this review, we examine the main virulence determinants in Helicobacter pylori (Hp) strains and the correlation between these and the different diseases following Hp infections. We also discuss the host response to Hp and the implications and advantages of the development of non-invasive pre-endoscopy screening of molecular and serological markers associated with Hp virulence and disease pro...
متن کاملThe intact dupA cluster is a more reliable Helicobacter pylori virulence marker than dupA alone.
The duodenal ulcer promoting (dupA) gene, located in the plasticity region of Helicobacter pylori, is associated with duodenal ulcer development. dupA was predicted to form a type IV secretory system (T4SS) with vir genes around dupA (dupA cluster). We investigated the prevalence of dupA and dupA clusters and clarified associations between the dupA cluster status and clinical outcomes in the U....
