Pneumococci can live in the nose and throat without causing illness. Explore its illustrative 3D model, human context, and sources.
Pneumococci can live in the nose and throat without causing illness. They can also cause pneumonia, meningitis, bloodstream infection, and ear or sinus infections. Symptoms depend on the infected body site. This profile separates carriage from disease; it cannot predict whether a colonized person will become ill.
Carriage is different from infection. Pneumonia and invasive infections can be serious; severity depends on the clinical context.
Encapsulated, lancet-shaped pair; no flagella. 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.
