Neisseria meningitidis (meningococcus). This bacterium is another leading cause of bacterial meningitis. These bacteria commonly cause an upper respiratory infection but can cause meningococcal meningitis when they enter the bloodstream. This is a highly contagious infection that affects mainly teenagers and young adults 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 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, a diplococcus because of its tendency to form pairs. About 10% of adults are carriers of the bacteria in. Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The most common symptoms are fever, headache, and neck stiffness. Other symptoms include confusion or altered consciousness, vomiting, and an inability to tolerate light or loud noises. Young children often exhibit only nonspecific symptoms, such as.
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 Clinical trials.

Neisseria meningitidis is a bacterium hosted only by humans and is a leading cause of bacterial meningitis in the United States. This pathogen may also cause overwhelming sepsis, purpura fulminans, or (rarely) benign meningococcemia. Meningitis (inflammation of the membranes surrounding the brain and spinal cord) is a common form of. Lessons From N. meningitidis. Unlike Neisseria meningitidis serogroups A, C, W, and Y, for which effective polysaccharide-protein conjugate vaccines have been developed, serogroup B has required alternative strategies. This is because of the poor immunogenicity of the group B capsular polysaccharide and its likely homology to fetal neural tissue ().. Meningococcus or Neisseria meningitidis, is a bacterium that can cause meningitis. The bacteria are germs that can be found in the rhinopharynx, where it can cause benign rhinopharyngitis or an asymptomatic state. Only one in 400 carriers become victim to a serious meningococcal disease, mostly commonly acute purulent meningitis Neisseria meningitidis isolates in the United States have been largely susceptible to the antibiotics recommended for treatment and prophylaxis. However, 11 meningococcal disease cases reported in the United States during 2019-2020 had isolates containing a bla ROB-1 β-lactamase gene associated with penicillin resistance, as well as.
