2018-08-07 · Neisseria meningitidis (the meningococcus) is the causative organism of meningococcal meningitis, because there are 2000 and 3000 cases of meningococcal meningitis per year in the U.S. In about 15% of these individuals, the organism invades the blood and disseminates, leading septicemia and from the there may cross the blood-brain barrier causing meningitis .

Meningitidis is described as a gram-negative diplococci. The fact that this bacteria is gram negative means that there is very little or no peptidoglycan in the cell wall. 2021-02-04 2016-09-15 2020-07-14 2020-07-12 Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae.Most gonococcal infections are asymptomatic and self-resolving, and epidemic strains of the meningococcus may be carried in >95% of a population where systemic disease occurs at <1% prevalence. Neisseria gonorrhoeae: Neisseria meningitidis: 1: Referred as: Referred to as gonococcus.

Morphology. Gram negative diplococci with flattened sides "kidney bean shaped", polysaccharide capsule present, not readily seen, but serves as the basis for serotyping. Endotoxic lipopolysaccharide complexed with protein in outer membrane; Capsules and pili; Cultural characteristics Young colonies of N. meningitidis are round, smooth, moist, glistening, and convex, with a clearly defined edge on a BAP . Some colonies appear to coalesce with other nearby colonies.

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,

Neisseria Meningitidis is a bacteria that can cause meningitis in the brain.

A report of “ presumptive N. gonorrhoeae ” or, ideally, to avoid confusion, “gram-negative, oxidase-positive diplococcus isolated” should be made if identification of the organism suspected to be N. gonorrhoeae is based on: Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals.

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.
