Additional Information:
|
Helicobacter is a genus of Gram-negative, nonsporulating, spiral-shaped and flagellated bacilli consisting of over 50 species commonly found in the human stomach and upper gastrointestinal tract. Helicobacter pylori, the type strain of the genus, is present in about half of the world population.3,4 It is an opportunistic pathogen linked to diseases of the upper gastrointestinal tract, including gastric and duodenal ulcers, chronic gastritis and stomach cancer.2 H. pylori infections are difficult to cure, and successful treatment generally requires the administration of several antibacterial agents simultaneously.5,6
