Helicobacter pylori colonization is associated with chronic gastritis, peptic ulcers, intestinal metaplasia, adenocarcinoma and lymphoma of the stomach. The objective of this study was to compare the results of the routinely used histology with molecular diagnosis for the detection of H. pylori. Eighty samples from gastric lesions (chronic gastritis, atrophic gastritis, gastric ulcer, and intestinal metaplasia), 18 gastric adenocarcinoma and 10 normal mucosa H. pylori-negative (control) samples were obtained. All samples were examined histologically (hematoxylin-eosin and Giemsa staining), and PCR amplifications of the species-specific antigen gene (H3H4) and urease A gene segment (H5H6) of H. pylori were made, using the human gene CYP1A1 for DNA quality...
