A stomach colonizer associated with inflammation and ulcer disease. Explore its illustrative 3D model, human context, and sources.
H. pylori is a curved or spiral bacterium that colonizes the mucus lining the human stomach. Infection may cause no noticeable symptoms. Persistent infection can cause stomach inflammation and peptic ulcers, and increases the risk of certain gastric cancers. Ulcer symptoms overlap with other conditions and do not establish H. pylori infection.
An infection can be silent. Not everyone infected develops an ulcer or cancer; clinical assessment and appropriate testing determine the context.
Helical, Gram-negative rod with illustrative polar flagellar tuft. Original educational illustration, not a microscopy reconstruction. Colours, layer thicknesses, contents, appendage counts and dimensions are schematic. Viewer motion is a turntable. Independent scientific review pending. The generation-time card uses a separate, condition-specific laboratory reference; the 3D phenotype and animation substages are illustrative, not measured growth dynamics of that strain.
