Meningococci can be carried in the back of the nose and throat without illness. Explore its illustrative 3D model, human context, and sources.
Meningococci can be carried in the back of the nose and throat without illness. When they invade, they can cause meningitis or bloodstream infection that worsens rapidly. Healthy carriage and invasive disease are separate states. The paired-cell model depicts an encapsulated phenotype; capsule expression differs among strains.
Invasive meningococcal disease is a medical emergency. Carriage alone does not mean a person has meningitis.
Encapsulated, kidney-shaped pair; no flagella shown. 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.
