Essentially, most cases of meningitis are as a result of infections from three bacteria, namely, Neisseria meningitidis, Streptococcus pneumonia and Haemophilus influenza type b, that cause meningococcal meningitis, pneumococcal meningitis and influenza, respectively 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, 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 INTRODUCTION. Infection with Neisseria meningitidis can produce a variety of clinical manifestations, ranging from transient fever and bacteremia to fulminant disease with death ensuing within hours of the onset of clinical symptoms.N. meningitidis is a common cause of community-acquired bacterial meningitis in both children and adults. (See Bacterial meningitis in children older than one. Topic Overview. Meningitis caused by Neisseria meningitidis is sometimes referred to as meningococcal disease.. Some people have Neisseria meningitidis in their throats without getting sick. But they can pass it to another person, who may get sick. Neisseria meningitidis causes meningitis in about 25 out of 100 people who get the illness every year in the United States. footnote
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. It is fastidious in its growth requirements and is very susceptible to adverse physical and chemical. Neisseria meningitidis is a well-known bacterium for causing meningitis. Primary Meningococcal Type C Arthritis: A Case Report and Literature Review Infections caused by Neisseria meningitidis (Nm), Streptococcus pneumoniae (Sp) and Haemophilus influenzae (Hi) are responsible for high morbidity and mortality rates among children and adults in many countries each year Neisseria meningitidis is an obligate human commensal bacterium that frequently colonises the upper respiratory tract. Person-to-person transmission occurs via direct contact or through dispersion of respiratory droplets from a carrier of the bacteria, and can lead to invasive meningococcal disease. Meningococcal disease is a serious and potentially life-threatening infection caused by the bacterium Neisseria meningitidis. N. meningitidis can be classified into 12 serogroups based on its capsular polysaccharide; serogroups A, B, C, W, X, and Y are the primary causes of meningococcal disease worldwide Neisseria meningitidis sequence type 11 is an emerging cause of urethritis. We demonstrate by using whole-genome sequencing orogenital transmission of a N. meningitidis sequence type 11 isolate causing urethritis in a monogamous couple of men who have sex with men. These results suggest dissemination of this clonal complex among low-risk patients

Neisseria meningitidis (the meningococcus) is a fastidious Gram-negative diplococcus that colonizes and invades only man. In genetic terms, its closest relative is the gonococcus, Neisseria gonorrhoeae. The entire genetic sequences of a serogroup A and a serogroup B meningococcus have been published Neisseria meningitidis, also called N. meningitidis or just meningococcus, is a gram-negative round bacterium that causes meningitis in humans, as well as life-threatening conditions like sepsis and disseminated intravascular coagulation.. Now, N. meningitidis has a thin peptidoglycan layer, so it doesn't retain the crystal violet dye during Gram staining Neisseria meningitidis bacteremia cause DIC and pupura fulminans,which account for poor prognosis. A-24-year-old woman was admitted to our hospital complaining of fever, and pain with purpura of her limbs.Gram-negative cocci was recovered from the blood culture on admission, which was indentified as.
Neisseria meningitidis. N.meningitidis is a Gram-negative coccus (round shape) that is the major cause of bacterial meningitis worldwide.N.meningitidis is divided into 'serogroups' based on the differences in their surface molecules and how the immune system responds to this. Serogrouping of N. meningitidis is done by looking at the similarity of their capsule (a sugary layer around the cell) Introduction. Neisseria meningitidis is a pathogenic species of bacteria which causes meningitis and/or septicaemia in children and young adults. It is responsible for both sporadic cases of meningitis and epidemics of the disease worldwide, producing considerable morbidity and mortality (Rouphael and Stephens, 2012) Neisseria meningitidis is a common cause of meningitis in young adults.Infected patients will present with the classic triad for meningitis: fever, stiff neck, and cognitive changes.Uniquely, this infection can cause the formation of a petechial or purpuric rash.. About 20% of patients will progress to a meningococcal septicemia mostly caused by the lipooligosaccharide (LOS) that resides in. Introduction. The Gram-negative species Neisseria meningitidis (the meningococcus) belongs to the β-subgroup of proteobacteria. They are facultative commensals, and their only habitat are humans with no other known reservoirs. Meningococci colonize the nasopharynx of up to 35% of healthy individuals at any given time, and direct person-to-person spread of meningococci occurs by large droplet.
Meningococcal meningitis is a rare but serious bacterial infection. It causes the membranes that cover the brain and spinal cord to become inflamed. Each year, approximately 1,000 people in the U. Overview. Neisseria meningitidis, also simply known as meningococcus, is a gram-negative diplococcal bacterium best known for its role in meningitis. It only infects humans; there is no animal reservoir.It is the only form of bacterial meningitis known to cause epidemics.. Strains. There are many strains of meningococcus; the most clinically important are A, B, C, Y and W135 Figure 1. Neisseria meningitidis scanning EM. Neisseria meningitidis, also known as meningococcus, is a parasitic, aerobic, Gram-negative, nonmotile, coccal bacterium that is responsible for causing meningitis and meningococcal septicemia, a serious condition that causes hemorrhaging of the skin.Symptoms of meningitis were first noted in 1805 but it was not isolated until 1887 by Weichselbaum Part of the explanation for this phenomenon is the fact that meningitis due to Neisseria meningitidis tends to strike young, previously well individuals and can progress over a matter of hours to death. Mortality can be very high if the infection is not treated appropriately, and long-term sequelae can be severe even in successfully managed cases
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.

In Neisseria gonorrhoeae and Neisseria meningitidis, we identified a gene that would encode a protein highly similar to NorM of Vibrio parahaemolyticus (Y. Morita et al., Antimicrob. Agents Chemother. 42:1778-1782, 1998). A nonpolar insertional mutation in either the gonococcal or meningococcal norM gene resulted in increased bacterial sensitivity to compounds harboring a quaternary ammonium.
