Helicobacter pylori is a motile, Gram-negative, spiral-shaped bacterium. It is associated with ulcer, gastritis, and gastric ulcer. It colonizes the upper intestinal tract and stomach’s non-acid-secreting mucosa. Once, the mucosa is colonized by the cells of H . pylori, a combination of host response and virulence factor leads to inflammation, destruction of tissue, and ulceration. The by-products of the pathogen such as, ureases, cytotoxin VacA, and an autoimmune response induced by H. pylori lipopolysaccharide altogether contribute to tissue devastation and ulceration.
