Helicobacter pylori is a spiral-shaped, Gram-negative bacillus whose causal role in inflammatory gastrointestinal diseases has been firmly established. H. pylori infection is detected in 90% of patients with duodenal ulcer and 70% of patients with gastric ulcer. The value of H. pylori eradication to ensure lasting and effective cure of duodenal ulcer has been clearly demonstrated. Testing for H. pylori infection constitutes an important diagnostic step in subjects presenting with gastroduodenal inflammatory symptoms.
