CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Kellogg (1, 2) was the first to recognize that Neisseria gonorrhoeae, when grown on solid agar, grew in distinctive colony types. BD Difco™ Neisseria Meningitidis Antisera are recommended for use in slide agglutination tests for serotyping Neisseria meningitidis. SUMMARY AND EXPLANATION Neisseria meningitidis, also known as meningococcus, is found in the oropharynx and nasopharynx of humans. Because the organism survives poorly in the environment, Colonial morphology and piliation were studied on twelve strains from various serogroups of Neisseria meningitidis. Six different colony types (M1 to M6) were identified.

Neisseria meningitidis morphology

It is 0.6–1.0 micrometers in size. It tests positive for the enzyme cytochrome c oxidase. Habitat. N. meningitidis is a part of the normal nonpathogenic flora in the nasopharynx of up to 8–25% of adults.

Neisseria meningitidis or meningococcus is a Gram-negative, oxidasepositive, aerobic, coccal bacterium that appears microscopically under diplococcal arrangement. Strains are serogrouped on the basis of their capsular polysaccharides. The meningococci are …

13 olika grupper av meningokocker har identifierats. Av dessa är grupperna A, B, C, W-135, X och Y sjukdomsframkallade. Neisseria meningitides . Meningitis. Meningitis is an inflammation of the leptomeninges and underlying subarachnoid cerebral spinal fluid. Acute (<24 hours), Sub-acute (1-7 days) and Chronic > 7 days Acute meningitis is almost always bacterial; N. meningitides causes meningitis and septicemia Neisseria menigitidis is a Gram-negative, aerobic, nonmotile, nonspore-forming, oxidase-positive, catalase-positive coccus. Most disease-causing strains of N. meningitidis belong to serogroups A, B, or C: serogroup A strains are often responsible for epidemic disease in developing countries, whereas serogroup B and C strains are more often associated with disease outbreaks in developed countries.

N. meningitidis is a major cause of cerebrospinal meningitis. 3: Vaccine Development: No: Serogroup A, B, C, Y and W-135 meningococcal infections can be prevented by 2011-09-09 1989-11-01 2020-03-24 Old synonyms: Diplokokkus intracellularis meningitidis Weichselbaum 1887, Neisseria weichselbaumii Trevisan 1889, Micrococcus intracellularis (Jaeger) Migula 1900, Micrococcus meningitidis cerebrospinalis Albrecht and Ghon 1901, Micrococcus meningitidis Albrecht and Ghon 1903.
