Study Notes
Neisseria meningitidis Overview
- Neisseria meningitidis is a gram-negative bacterium, not gram-positive.
- Characterized as non-motile and non-spore forming, indicating a lack of mobility and the absence of a durable reproductive structure.
Pathogenic Potential
- Capable of causing asymptomatic pharyngitis, particularly in young children, which may go unnoticed and facilitate the spread of the bacteria.
- The bacterium features an antiphagocytic capsule that aids in evading the immune system by preventing phagocytosis.
Disease Manifestation
- When introduced into the bloodstream, Neisseria meningitidis can lead to serious conditions such as meningitis (inflammation of the protective membranes covering the brain and spinal cord) and septicemia (blood poisoning).
