Person to person transmission is considered to be the most likely route of transmission of Helicobacter pylori. H. pylori is a noninvasive organism. It is found over mucus secreting cells but not in deeper gastric glands. Hence it can only inhabit gastric-type mucus but cannot colonize the esophagus or duodenum. Pathogenesis of H. pylori infection depends on bacterial, host and environmental factors.
