Summary Introduction
Introduction:
Helicobacter pylori is an ulcer causing, gram-negative bacteria found in the human stomach. This bacteria is able to survive the acidic environment and thereby it causes the gastritis and ulcer. After colonizing the stomach, it penetrates the inner lining of the mucus membrane and causes ulceration or wounds. It is one of the most dangerous pathogen in the developing countries.
