Meningitis and Encephalitis :: Biology Medical Biomedical

Meningitis and EncephalitisMeningitis and encephalitis ar two drain infections. They begin the inflammation of the meninges and the brain, respectively. Both of these infections argon more ordinary than the public believes them to be. Al to the highest degree any bacteria or viruses can cause a form of this infection and any person of any get on with can contract this illness.In the United States many cases of meningitis and encephalitis are reported yearly. These two illnesses are often confused and considered by the world(a) public to be one illness. But that is a myth. Meningitis and encephalitis are related, however, since encephalitis usually stems from the former. But meningitis causes inflammation of the meninges, or the lining of the brain, magic spell encephalitis inflames the brain itself. Both of these inflammations have two forms viral and bacterial. at that place are many different viruses that cause meningitis, such as epidemic parotitis virus, echovirus, human entroviruses, HIV, arborviruses, west nile viruses, and many others. Mumps virus and Enteroviruses are the most common viruses that cause this infection. Viral meningitis tends to be more prevalent during the spend months. It is more likely to be found in adolescents or adults.bacterial meningitis, like viral meningitis, is caused by many different organisms. Fifty percent jump on of bacterial meningitis is caused by Streptococcus pneumoniae, and fifteen percent are caused by Neisseria meningitides. The rest is caused by different Streptococcus and Listeria bacteria. Bacterial meningitis is contagious through direct contact with the oral fluids of the effected person. Therefore, the significant other and home plate contacts are often a likely candidate to contract bacterial meningitis. Eightypercent of cases are in people under the age of 16 and the majority of that group is under 5-years old.Haemophilus influenzae are gram-negative rods and it is usually found in the United St ates. Their cell has a polysaccharide enfold with outer-membrane proteins. It is also non-motile. This bacterium prefers a carbon dioxide rich atmosphere though some strains do not need it to survive. An unusual trait of this bacteria is that when it is cultured for a long time, it loses its capsule and then dies. H. influenzae causes most cases of meningitis that slide by in children between the ages of 2 months to four years, although-the mortality rate is a low three percent.Neisseria meningitides is a gram-negative diplococci, or a cocci that travels in pairs. This species is one of two Neisseria that are harmful to people. It is a planetary bacterium with a polysaccharides capsules.
