Neisseria meningitidis is a gram-negative diplococcus and is a member of the family Neisseriaceae within the order Eubacteria. This family includes the genera Neisseria, Moraxella, Kingella, and Acinetobacter. The genus Neisseria includes two human pathogens, Neisseria gonorrhoeae and Neisseria meningitidis (the meningococcus). The meningococcus is enveloped by a polysac-charide capsule, which is essential for pathogenicity. Differences in the immunological reactivity of the capsule define 13 serogroups of which five (A, B, C, W135, and Y) are most commonly associated with invasive menin-gococcal disease.
