- Neisseria meningitidis (pron. meningìtidis), conosciuto anche come meningococco, è un batterio Gram-negativo, un microrganismo che colonizza esclusivamente la specie umana. È l'agente eziologico della meningite batterica e di alcune setticemie che pongono ad alto rischio la vita del paziente (meningococcemia).. Venne scoperto da Giovanni Battista Ughetti nel 1880 e poi isolato e coltivato.
- Neisseria meningitidis, often referred to as meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis.The bacterium is referred to as a coccus because it is round, and more specifically, diplococcus because of its tendency to form pairs. . About 10% of adults are carriers of the bacteria in.

- Neisseria meningitidis (Nm) serogroup W (NmW) is one of the six meningococcal serogroups that cause majority of invasive meningococcal diseases. Its capsular polysaccharide (CPS) is a virulence factor and is a key component in NmW CPS-protein conjugate vaccines. The current clinically used NmW CPS-protein conjugate vaccines are effective, but the costs are high and the products are.
- Abstract. In 2000, a large international outbreak of meningococcal disease caused by Neisseria meningitidis serogroup W-135 was identified among pilgrims returning from the Hajj in Saudi Arabia. To assess ongoing risk, we evaluated N. meningitidis carriage among US travelers to the 2001 Hajj. Of 25 N. meningitidis isolates obtained, 15 (60%) were nongroupable and 8 (32%) were serogroup W-135.

In 2010, Burkina Faso became the first country to introduce meningococcal serogroup A conjugate vaccine (PsA-TT). During 2012, Burkina Faso reported increases in Neisseria meningitidis serogroup W, raising questions about whether these cases were a natural increase in disease or resulted from serogroup replacement after PsA-TT introduction.

- Meningococcal meningitis, caused by Neisseria meningitidis bacteria, is of particular importance due to its potential to cause large epidemics. Twelve types of N. meningitides, called serogroups, have been identified, six of which (A, B, C, W, X and Y) can cause epidemics.. Meningococcal meningitis is observed in a range of situations, from sporadic cases, small clusters, to huge epidemics.

Additionally, serogroup X is still not represented in current conjugated meningococcal vaccines Neisseria meningitidis is a cause of invasive meningococcal disease (IMD) that is associated with outbreaks of epidemic and endemic infections, with high morbidity and mortality worldwide [ 1 ]
Neisseria meningitidis Serogroup W-135 Carriage among US
- Infection with Neisseria meningitidis(the meningococcus) usually results in an asymptomatic, or only mildly symptomatic, infection of the pharynx; invasion of the blood stream and invasive disease is a rare event. Study of pharyngeal carriage is, therefore, essential for a full understanding of the epidemiology of meningococcal infection

Neisseria meningitidis - an overview ScienceDirect Topic
- 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
- Meningococcal vaccine refers to any of the vaccines used to prevent infection by Neisseria meningitidis. Different versions are effective against some or all of the following types of meningococcus: A, B, C, W-135, and Y. The vaccines are between 85 and 100% effective for at least two years. They result in a decrease in meningitis and sepsis among populations where they are widely used
- Neisseria meningitidis (Nm) remains a leading cause of meningitis and rapidly fatal sepsis in otherwise healthy individuals. Historically, Nm is not recognized as a significant cause of urogenital infections. Since 2015, a significant increase of meningococcal urethritis primarily among heterosexual men has been reported in multiple US cities
