  • Neisseria meningitidis - Wikipedia


    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. It has also been reported to be transmitted through oral sex and cause urethritis in men.

  • Neisseria - Wikipedia


    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.

  • Neisseria meningitidis - microbewiki


    Description and Significance. Neisseria meningitidis is a parasitic, aerobic, Gram-negative, non endospore forming, nonmotile (although piliated) , coccal bacterium that is responsible for causing meningitis, inflammation of the meninges layer covering the brain. Because it is an aerobic organism, like most members of the Neisseriaceae family, it also has catalase and oxidase activity.

  • Meningococcal disease - Wikipedia


    Meningococcal disease describes infections caused by the bacterium Neisseria meningitidis (also termed meningococcus). It has a high mortality rate if untreated but is vaccine-preventable. While best known as a cause of meningitis, it can also result in sepsis, which is an even more damaging and dangerous condition.

  • Neisseria gonorrhoeae - Wikipedia


    Neisseria gonorrhoeae, also known as gonococcus (singular), or gonococci (plural) is a species of Gram-negative diplococci bacteria isolated by Albert Neisser in 1879. It causes the sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic arthritis, and gonococcal ophthalmia neonatorum.

  • Overwhelming post-splenectomy infection


    An overwhelming post-splenectomy infection (OPSI) or Overwhelming post-splenectomy sepsis (OPSS) is a rare but rapidly fatal infection occurring in individuals following removal of the spleen. The infections are typically characterized by either meningitis or sepsis, and are caused by encapsulated organisms including Streptococcus pneumoniae. Another source of infection are varieties of babesia, which are tick-borne parasites that cause babesiosis. Capnocytophaga canimorsus can trigger infection after dog bites. The risk of OPSI is 0.23–0.42 percent per year, with a lifetime risk of 5 percent. Most infections occur in the first few years following splenectomy, but the risk of OPSI is lifelong. OPSI is almost always fatal without treatment, and modern treatment has decreased the mortality to approximately 40–70 percent. Individuals with OPSI are most commonly treated with antibiotics and supportive care. Measures to prevent OPSI include vaccination and prophylactic antibiotics.

  • Thayer-Martin agar


    Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria.Known as overgrowth, note that the non-selective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of Neisseria gonorrhoeae, while the selective Thayer-Martin medium on the right, containing antimicrobials that inhibit the growth of organisms other than N. gonorrhoeae, shows no overgrowth, but is positive for N. gonorrhoeae bacteria.Thayer-Martin agar (or Thayer-Martin medium) is a Mueller-Hinton agar with 5% chocolate sheep blood and antibiotics. It is used for culturing and primarily isolating pathogenic Neisseria bacteria, including Neisseria gonorrhoeae and Neisseria meningitidis, as the medium inhibits the growth of most other microorganisms. When growing Neisseria meningitidis, one usually starts with a normally sterile body fluid (blood or CSF), so a plain chocolate agar is used. Thayer-Martin agar was initially developed in 1964, with an improved formulation published in 1966.
