Neisseria meningitidis

  1. Neisseria meningitidis (též meningococcus, meningokok) je gramnegativní diplokokální bakterie, původce jednoho typu meningitidy. Infikuje jen člověka, neexistují žádné jiné přirozené rezervoáry
  2. Meningococcal disease is caused by bacteria called Neisseria meningitidis. People with meningococcal disease spread the bacteria to others through close personal contact such as living together or kissing. A person with meningococcal disease needs immediate medical attention
  3. 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

Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill. This is called being 'a carrier'. Sometimes the bacteria invade the body and cause certain illnesses, which are known as meningococcal disease Neisseria meningitidis (meningokok) z rodu bakterií Neisseria, které patří mezi Gram-negativní koky, je kosmopolitní bakterie, která vyvolává invazivní meningokoková onemocnění (IMO).

Neisseria meningitidis. N. meningitidis (the meningococcus) is a Gram-negative bacterium, and a major causative agent of bacterial meningitis and severe sepsis. Meningococcal infections are a leading cause of morbidity and mortality worldwide, therefore understanding their molecular biology is crucial to develop therapeutics such as vaccines Neisseria meningitidis is a leading cause of bacterial meningitis and sepsis worldwide and an occasional cause of meningococcal urethritis. When isolates are unavailable for surveillance or outbreak investigations, molecular characterization of pathogens needs to be performed directly from clinical specimens, such as cerebrospinal fluid (CSF), blood, or urine

Abstract. Background: Since 2010, there has been an increase in serogroup W Neisseria meningitidis (MenW) disease in many countries due to an emerging sequence type-11 clonal complex (ST-11 CC). In 2016, a small increase in MenW disease due to the ST-11 CC was documented in Ontario, Canada.

Wellcogen™ N. meningitidis ACY W135 is a rapid latex test for use in the qualitative detection of antigen from Neisseria meningitidis (meningococcus) groups A, C, Y and W135, present in body fluids as a consequence of infection or in blood cultures. NOTE: Tests performed directly on clinical specimens are intended for screening purposes and should augment, not replace, culture procedures Neisseria meningitidis isolate identification is confirmed by biochemicals. Grouping is performed by serological method. The specimen is also forwarded to the Public Health Agency of Canada in Winnipeg for further typing Neisseria Meningitidis is a bacteria that is best known for its role in endemic bacterial meningitis.N. 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 Background Neisseria meningitidis is a significant cause of morbidity and mortality worldwide.

The bacteria can cause septicemia, pneumonia, and meningitis. N Meningococcus. A major human pathogen belonging to the bacterial genus Neisseria, and the cause of meningococcal meningitis and meningococcemia.The official designation is N. meningitidis.The meningococcus is a gram-negative, aerobic, nonmotile diplococcus Neisseria meningitides. Neisseria meningitides is an aerobic, non-spore-forming Gram-negative coccobacilli that resides in its natural habitat within the nasopharyngeal tract of humans . 5-15% of the human population carries the bacteria in its nonpathogenic form .(a major step in infection is its colonization in the nasophrynx of the human carrier ) Neisseria meningitidis, also simply known. Medical definition of Neisseria: a genus (the type of the family Neisseriaceae) of parasitic bacteria that grow in pairs and occasionally tetrads, thrive best at 98.6°F (37°C) in the animal body or serum media, and include the gonococcus (N. gonorrhoeae) and meningococcus (N. meningitidis)
