Neisseria meningitidis o meningococo es una bacteria Gram-negativa, oxidasa-positiva, aeróbica, que microscópicamente aparece como diplococos. Las distintas cepas se clasifican en serogrupos en función de los polisacáridos de la cápsula.

Provtagning och transport. Provtagningsset meningokocksjukdom orsakad av grupp B av bakterien Neisseria meningitidis. Invasiv sjukdom uppstår när bakterierna sprids i kroppen och orsakar allvarliga Kliniska prövningar på Neisseria Meningitidis-infektion. Registret för kliniska prövningar.

Budowa Neisseria meningitidis nie odbiega od budowy innych bakterii Gram-ujemnych – komórka jest otoczona błoną zewnętrzną złożoną z lipidów, białek błony zewnętrznej (OMP) i lipopolisacharydów (LPS). Neisseria meningitidis. Agente Infeccioso: Neisseria meningitidis: Referencia cruzada/ sinónimos: Meningitis meningocóccica, Infección por meningococos, fiebre Pathogenic Neisseria meningitidis isolates contain a polysaccharide capsule that is the main virulence determinant for this bacterium. Thirteen capsular polysaccharides have been described, and nuclear magnetic resonance spectroscopy has enabled determination of the structure of capsular polysaccharides responsible for serogroup specificity. CULTURE REQUIREMENTS OF NEISSERIA MENINGITIDIS (MENINGOCOCCUS) ⇒ Special requirements – Meningococci or Neisseria meningitidis have complex nutritional requirements and readily grow in a media containing Blood or Serum, commonly Blood Agar medium, Chocolate Agar medium & Mueller Hinton Agar medium is used for the cultivation of Neisseria meningitidis in Laboratory.

This may result from the phase variability of some Neisseria genes.N. meningitidis can be cultured successfully in a low‐carbohydrate medium, such as Mueller–Hinton broth (MHB 2018-05-30 SECTION I - INFECTIOUS AGENT.

Neisseria meningitidis (the meningococcus) causes significant morbidity and mortality in children and young adults worldwide through epidemic or sporadic

Neisseria meningitidis is a gram-negative bacterium that lives in the human nasopharynx, and it is commonly found among the commensal flora of about 10% of asymptomatic carriers. However, this bacterium can provoke severe systemic infections such as septicemia (with or without shock) and meningitis. Neisseria meningitidis is a leading worldwide cause of sepsis and meningitis, with the highest increase in infants, young children, and adolescents resulting in significant morbidity and mortality. The pathogen has a unique ability among the different etiologic agents of bacterial meningitis to cause major epidemics, case clusters, and hyperendemic as well as endemic disease. 2015-12-01 · Neisseria meningitidis is an extracellular pathogen, meaning that it colonizes and proliferates in the extracellular fluid and blood.

Personer i alla åldrar kan drabbas men yngre Neisseria meningitidis kan orsaka allvarlig invasiv sjukdom - framför allt sepsis, meningit eller en kombination av dessa. Meningokockinfektioner drabbar framför Neisseria meningitidis (diagnostik).

2015-12-01 · Neisseria meningitidis is an extracellular pathogen, meaning that it colonizes and proliferates in the extracellular fluid and blood. To escape the body’s defences, the major asset of N. meningitidis is the biosynthesis of a capsule made of sialic acid that covers the bacteria and protects it from the host’s immune system.

Die Polysaccharidkapsel von Neisseria meningitidis verhindert die Phagozytose des Erregers und unterstützt die Immunevasion. CHARACTERISTICS: Neisseria meningitidis belongs to the family Neisseriaceae Footnote 2. It is a Gram-negative, non-spore forming, non-motile, encapsulated, and non acid-fast diplococci, which appears in kidney bean shape under the microscope Footnote 1 .
