Relationship between Helicobacter Pylori Morphological Forms in Gastric Biopsy and Helicobacter Pylori Stool Antigen

Abstract

Background: Helicobacter pylori (H. pylori) is a gram-negative, spiral-shaped microorganism and is responsible for colonization in the gastric microniche of more than 50% of the world population. This work aimed to compare H. pylori stool antigen titer in different H. pylori morphological forms in gastric biopsy. Patients and Methods: This study was carried out on 120 patients with dyspepsia. All patients were subjected to full history taking, upper GI endoscopy, and gastric biopsies according to Sydney protocol for histopathology and stool antigen test by using the H.
