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 Introduction. Neisseria meningitidis is a human commensal bacterium that commonly colonizes the oropharyngeal mucosa, occasionally causing life-threatening disease, such as meningitis or septicemia [] Meningococcal populations possess a diverse and dynamic structure [2,3].However, most invasive meningococcal cases are caused by a limited number of clonal complexes (cc), known as hyperinvasive. 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 Thirteen Neisseria meningitidis serogroups have been described on the basis of serologic differences of the capsule; of these 13 serogroups, 6 (A, B, C, W, X, Y) cause invasive meningococcal disease. The polysaccharide capsule is a key virulence determinant, and for serogroups A, C, W, and Y, it forms the basis of polysaccharide conjugate vaccines Objective The aim of this study was to determine the prevalence of Neisseria meningitidis, Haemophilus influenzae, Streptococcus pneumoniae, group A Streptococcus (GAS), and Staphylococcus aureus in asymptomatic elderly people and to unravel risk factors leading to colonization. Methods A multi-centre cross-sectional study was conducted including 677 asymptomatic adults aged 65 years or more.

NCBI TAXONOMY NCBI Organism Name Neisseria meningitidis alpha710: NCBI Tax ID 63058 Meningitis can result from many causes, both infectious and non-infectious. Bacterial meningitis is a life-threatening condition that requires prompt recognition and treatment. Beyond the newborn period, the most common causes of bacterial meningitis are Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae. All three of. Introduction. 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 [].Although the natural reservoir of N.meningitidis is the human upper respiratory tract, it can invade the bloodstream and is the cause of meningitis in 30%-60% of cases; it also causes.

It is caused by Neisseria meningitidis, which normally resides in the upper respiratory tract of healthy carriers. For reasons not completely understood, N. meningitidis may invade the blood stream and cause serious systemic infection leading to meningitis, septicemia, septic arthritis, bacteremic pneumonia and pericarditis Footnote 2. Initial clinical presentation of IMD can be nonspecific but it may progress rapidly, leading to septic shock Менінгокок (лат.

meningococcus. Neisseria meningitidis (ב תעתיק ל עברית: ניסריה מנינגיטידיס, מוכר גם בשם: מנינגוקוקוס, או בפשטות החיידק האלים) הוא חיידק גראם-שלילי דיפלוקוקי מהסוג Neisseria. הוא נוטה להתיישב ב אף וב לוע של ילדים ומבוגרים בריאים, ובדרך כלל אינו גורם לבעיות כלשהן, אך הוא מסוגל לעבור מאדם לאדם. Neisseria meningitidis commonly causes meningitis in the African meningitis belt, where periodic meningococcal epidemics have contributed to the highest reported incidence of meningococcal meningitis in the world ().Most meningococcal disease historically has been caused by N. meningitidis serogroup A (NmA); however, NmA disease dramatically decreased after the preventative MenAfriVac. Neisseria meningitidis, [1] generalmente denominada meningococo, es una bacteria gramnegativa que puede causar meningitis y otras formas de enfermedad meningocócica, por ejemplo meningococemia, un tipo de sepsis potencialmente mortal.

The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains. Meningococcal disease refers to any illness caused by bacteria called Neisseria meningitidis, also known as meningococcus [muh-ning-goh-KOK-us].These illnesses are often severe and can be deadly. They include infections of the lining of the brain and spinal cord (meningitis) and bloodstream infections (bacteremia or septicemia) Meningitis is an inflammation (swelling) of the protective membranes covering the brain and spinal cord. A bacterial or viral infection of the fluid surrounding the brain and spinal cord usually causes the swelling. However, injuries, cancer, certain drugs, and other types of infections also can cause meningitis Meningococcal meningitis, a bacterial form of meningitis, is a serious infection of the meninges that affects the brain membrane. It can cause severe brain damage and is fatal in 50% of cases if untreated. Twelve types of N. meningitides, called serogroups, have been identified, six of which (A, B, C, W, X and Y) can cause disease and epidemics Commonly referred to as the meningococcus. Neisseria meningitidis is a Gram-negative diplococcus, typically flattened where the cocci meet. Oxidase positive. Aerobic. There are 13 serogroups of meningococci. Serogroups B and C commonly cause meningitis and meningococcemia in developed countries; serogroups Y and W135 typically cause pneumonia

Background Neisseria meningitidis serogroup B remains a prominent cause of invasive meningococcal disease (IMD) in Brazil. Because two novel protein-based vaccines against serogroup B are available, the main purpose of this study was to provide data on the diversity and distribution of meningococcal vaccine antigen types circulating in Brazil The NCBI PubMed database was used with search terms Neisseria meningitidis and PCR (date of access: November 2011). The different techniques and detection algorithms were evaluated in order to define the most appropriate ones for our context The case report presents a unique situation: an uncommon etiology of neonatal meningitis and favorable evolution, despite neurological sequels reported in the literature. [ncbi.nlm.nih.gov] Comparative analysis showed that four genes are uniquely present in H44/76 and nine genes are only present in MC58. Of all ORFs in H44/76, 2,317 (93%) show more than 99% sequence identity Neisseria meningitidis). Up to 25% of those who survive are left with permanent sequelae, which may include amputation of limbs, mental retardation, and hearing loss (2, 3).The bacteria have been classified in serogroups based on the chemical composition of the polysaccharide capsule ().Although 13 chemically different serogroups have been described, only serogroups A, B, C, Y, and W-135, and.

We focused on the role of D-dimer assessed within 24 h after admission in predicting clinical outcomes in a cohort of 270 patients hospitalized in a 79 months period for meningitis and/or bloodstream infections due to Streptococcus pneumoniae (n = 162) or Neisseria meningitidis (n = 108) By Molly Folks. Neisseria meningitidis (N. meningitidis) is Gram-negative bacterium that is a member of the class, Betaproteobacteria.Neisseria are aerobic heterotrophic cocci, and the cocci of Neisseria genus form diplococci, distinctive pairs of cocci (Fig 1) .Most members of the Neisseria genus are commensal organisms that colonize the nasal and oral mucosa of animals In 1928, Neisseria flavescens was first isolated from cerebrospinal fluid in the midst of an epidemic meningitis outbreak in Chicago. These gram-negative, aerobic bacteria reside in the mucosal membranes of the upper respiratory tract, functioning as commensals. However, this species can also play a pathogenic role in immunocompromised and diabetic individuals 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 Serogroup B Neisseria meningitidis strains belonging to sequence type 4821 clonal complex (CC4821), a hyperinvasive lineage first identified for serogroup C in 2003, have been increasingly isolated in China.
