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 gonorrheae 1. NEISSERIA GONORRHEAE Itzia María Magaña Hernández 2. Son dipolococos gram negativo Son anaerobios Son inmóviles Son oxidasa y catalasa positivos 3.

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. Neisseria sp. have the ability to reduce nitrite (via nitric oxide) to nitrous oxide. The enzyme that catalyzes the nitrite reduction to nitric oxide is a two‐domain, copper‐containing nitrite reductase, AniA, which is predicted to be in the periplasm and attached covalently to the outer membrane by a palmityl residue via a lipoprotein anchor S.A.S. Hanna, in Encyclopedia of Food Microbiology, 1999. Bacterial Characteristics. Neisseria spp. are a Gram-negative non-spore-forming diplococcus that has a flattened shape; its size ranges between 0.6-0.8 μm. They are oxidase-positive, non-acid-fast cocci or plump rods. They can reach a diameter of around 0.6-0.8 μm and sometimes up to 1.0 × 2.0-3.0 μm About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators.

These are bacteria that define the opposite of the gram-positive bacteria in relation to the differential staining technique. During gram staining, the gram-negative bacteria will lose the crystal violet dye color after a wash with alcohol and take up the pink/red color of the counterstain, safranin..

Pathogenic bacteria are bacteria that can cause disease. This article deals with human pathogenic bacteria. Although most bacteria are harmless or often beneficial, some are pathogenic, with the number of species estimated as fewer than a hundred that are seen to cause infectious diseases in humans. By contrast, several thousand species exist in the human digestive system Neisseria gonorrhoeae and Neisseria meningitidis are two important pathogens in this group.

Summary. Meningitis is a serious infection of the meninges in the brain or spinal cord that is most commonly viral or bacterial in origin, although fungal, parasitic, and noninfectious causes are also possible. Enteroviruses and herpes simplex virus are the leading causes of viral meningitis, while Neisseria meningitidis and Streptococcus pneumoniae are the pathogens most commonly responsible.
