Organism Additional Information Helicobacter pylori is a Gram-negative, microaerophilic, human gastric pathogen classified by WHO as a Type 1 carcinogen. Its lipopolysaccharide (LPS) O antigen is responsible for its virulence. Lewis antigens on its O polysaccharides mimic glycan structures on human cells and interact with the C-type lectin DC-SIGN on dendritic cells, thereby down-regulating an inflammatory response. It also causes chronic type B gastritis (a prerequisite for duodenal ulcers) and is linked with mucosa-associated lymphoid tissue (MALT) and with B-cell MALT lymphomas.
