a bacterial species found in the nasopharynx of humans but not in other animals; the causative agent of meningococcal meningitis and meningicoccemia; virulent organisms are strongly gram negative and occur singly or in pairs; in the latter case the cocci are elongated and are arranged with long axes parallel and facing sides kidney shaped; groups characterized by serologically specific capsular polysaccharides are designated by capital letters (the main serogroups being A, B, C, and D).

Considerable evidence indicates that complementmediated serum bactericidal antibody (SBA), induced by naso- or oropharyngeal colonization or vaccination, confers protection against meningococci (8,9).
The data from this co-culture model system suggest that meningococci may undergo important transcriptional changes when they enter the human nasopharynx and encounter resident bacterial populations.
Meningococci are commonly found in their nasopharyngeal or tonsillar mucosa.
He said: "It is bound to hasten the development of comprehensive vaccines that offer protection against all virulent meningococci."
The median age of patients with SYMD was 16 years compared with 2 years for patients with disease caused by non-serogroup Y meningococci. Although patients with SYMD were more likely to present with purulent sputum (six [14%] versus one [2%]) and chest pain (eight [19%] versus one [2%]), they were not more likely to have an infiltrate on chest radiograph (seven [23%] versus 10 [20%]).
