Resumen

Helicobacter pylori is a Gram-negative, spiral, microaerophilic bacterium that originally colonizes the human stomach. Chronic H. pylori infection has been associated with chronic gastritis, peptic ulcer disease, atrophic gastritis, mucosa associated lymphoid tissue (MALT) lymphoma, and gastric cancer. H. pylori has been also detected in the mouth and the middle ear as well as in tonsillar and adenoid tissues. However, the relationship of H. pylori with the pathogenesis of diseases that involve these organs is controversial. Accumulated reports show controversies regarding the role of H. pylori in oropharyngeal infection. The hypothesis that H. pylori can colonize tonsillar and adenoid tissue has not yet been well elucidated due to the difficulty in isolating viable H. pylori. The results of this study indicate that viable H. pylori can be detected in the tonsillar tissues of chronic tonsillitis patients using a combination of conventional culture and histological examination employing modified Giemsa staining and immunohistochemistry.
