Prompt diagnosis and treatment of meningococcal disease are important due to risk of severe morbidity and death. Bacterial meningitis is life threatening, and must be distinguished from the more Meningococci (Neisseria meningitidis) are gram-negative diplococci that cause meningitis and meningococcemia. It is a devastating infection with a high mortality rate and is the second most common cause of community-acquired adult bacterial meningitis after Streptococcus pneumoniae. Even if treated quickly, meningococcal disease can cause long-term problems or be deadly. Getting vaccinated is the best way to prevent meningococcal disease N. meningitidis was estimated to be responsible for million cases of infection per year, as well as approximately, deaths worldwide. Infants and adolescents are most vulnerable to developing meningococcal disease due to elevated rates of nasopharyngeal colonization and waning maternal antibodies identification of Neisseria meningitidis (the meningococcus), Streptococcus pneumoniae (the pneumococcus) and Haemophilus influenzae from the cerebrospinal fluid and blood of patients with clinical meningitis Knowledge of the etiology and epidemiology of infectious meningitis and encephalitis can help clinicians better test for the patho-gens that are more likely to be causative. Colonies are positive by the oxidase test and most strains utilize maltose Clinical Features. Even if treated quickly, meningococcal disease can N. meningitidis and Streptococcus pneumoniaeCommon agents in adults include N. meningitidis and S. pneumoniae, but Listeria monocytogenes must also be considered, meningitis is a medical emer gency with a potential for high mor bidity and mortality. Two clinically overlapping syndromes – meningitis and bloodstream infection (meningococcaemia)are caused by infection with N. meningitidis (meningococcal the biology of N. meningitidis, including the pathology, epidemiology of carriage and disease populations, methods used for meningococcal typing and public health Meningitis is one of the four largest contributors of neurological disability-adjusted life years (DALY) globallyIn the U.S., from, there were approximately seven Most cases of meningitis probably occur following bacteraemia but the high incidence of pneumococcal meningitis in patients with sinusitis and otitis media suggest that direct Meningococcal disease is a rare, but very serious illness caused by a type of bacteria called Neisseria meningitidis. N. meningitidis is a fastidious, encapsulated, aerobic gram-negative diplococcus. Empirical therapy for suspected meningococcal disease is an extended-spectrum cephalosporin, such as cefotaxime or ceftriaxone It can also guide public health policies, such as vacci-nation programs, targeting the disease vectors and improving crowded living conditions Key Points. Symptoms, usually severe, include headache, nausea, vomiting, Neisseria meningitidis, often referred to as the meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as Neisseria meningitidis (Nm), also referred to as meningococci are fastidious, aerobic Gram-negative diplococci with adjacent sides flattened (lens-shape/half-moon-shaped)N meningitidis is a common and significant cause of community-acquired bacterial meningitis in the United States, affecting children and adults. Meningococcal disease is a serious and potentially life-threatening infection. [7] In this review, we describe the biology, microbiology, and epidemiology of this exclusive human pathogen. Common signs and symptoms of meningococcal disease include sudden onset of high fever, neck stiffness, confusion, nausea, vomiting, lethargy, and petechial or purpuric rash Meningococcal disease is a rare, but very serious illness caused by a type of bacteria called Neisseria meningitidis.
