Helicobacter pylori is a Gram–negative bacteria with strong association with upper gastrointestinal diseases such as peptic ulcer disease (gastric ulcer, duodenal ulcer) and malignancies (gastric cancer, lymphoma), reported worldwide (1). In developing countries, H. pylori is typically acquired in early childhood and may persist for a lifetime if left untreated (2). In adults, the H. pylori infection rate increases with age (3). Oro–oral and feco–oral routes are the most common modes of H. pylori transmission in developing countries. Less common modes of transmission are zoonotic and iatrogenic (such as endoscopic or through dental procedures) transmissions (4).
