The shape of Stretococcus pneumoniae is also N. meningitidis colonizes mucosal surfaces using a multifactorial process involving pili, twitching motility, LOS, opacity associated, and other surface proteins. Certain clonal groups have an increased capacity to gain access to the blood, evade innate immune responses, multiply, and cause systemic disease. Meningokocker (lat. Neisseria meningitidis) är en grupp bakterier som bland annat kan orsaka hjärnhinneinflammation (meningit). Personer i alla åldrar kan drabbas men yngre barn och unga vuxna får det oftare än andra. 13 olika grupper av meningokocker har identifierats. Av dessa är grupperna A, B, C, W-135, X och Y sjukdomsframkallade.

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. 2017-03-31 N. Meningitidis has been divided into atleast 13 serogroups on the basis of specificity of capsular polysaccharide antigens.

Characterisation of Neisseria meningitidis from a virulence and. MORPHOLOGY OF NEISSERIA MENINGITIDIS (MENINGOCOCCUS) Shape – Neisseria meningitidis is an oval or spherical (coccus) shape bacterium with the adjacent side flattened. Size – The size of Neisseria meningitidis is about 0.6 µm – 0.8 µm (micrometer). Arrangement Of Cells – Neisseria meningitidis is arranged in pairs (diplococci), with the adjacent side flattened and they are usually present intracellularly when direct microscopic examination of the specimen from the lesions is carried It can grow on both a blood agar plate (BAP) and a chocolate agar plate (CAP). Colonies of N. meningitidis are grey and unpigmented on a BAP and appear round, smooth, moist, glistening, and convex, with a clearly defined edge. N. meningitidis appear as large, colorless-to-grey, opaque colonies on a CAP. Prior to identification and characterization testing procedures, isolates should always be inspected for purity of growth and a single colony should be re-streaked, when necessary, to obtain Neisseria species may be misidentified as N. meningitidis in acid detection tests.

N. meningitidis is a Gram-negative diplococcus since it has an outer and inner membranes with a thin layer of peptidoglycan in between. 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.

Catalase-positive. Colistin Resistance. Colistin-resistant. Neisseria species may be misidentified as N. meningitidis in acid detection tests. Supplemental tests may be used to differentiate between them.
