Meningitis means inflammation of the membranes surrounding the brain and spinal cord called the meninges. It often occurs when an infection elsewhere in the body spreads through the blood and into the cerebrospinal fluid (the fluid that circulates in the spaces in and around the brain and spinal cord). People can get meningitis at any age. There are several types of meningitis, and their severity and treatment can vary depending on which type a person has. Most cases of meningitis are caused by viruses (viral meningitis) or bacteria (bacterial meningitis), but fungi and other organisms can also cause infectious meningitis. Some cases of meningitis result from head injuries, certain cancers or other diseases, or reactions to medications. Classification of meningitis
The taxonomical classification for meningitis is Neisseria meningitis. Structure of meningitis
The crystal structure also identified two amino acids (Glu 304, Glu 341) in the bacterial protein that are crucial to allow its binding to factor H. When these two amino acids were mutated, surface proteins no longer bind factor H. The information provided by the crystal structure could thus lead to better protection against meningitis B, as vaccines containing the mutated bacterial protein may provoke a better immune response than those currently available.
Preferable host of meningitis
Anyone can contract bacterial meningitis, but it is most common in infants, children, and the elderly. Hib meningitis is most common in children 18 months to 4 years of age, meningococcus meningitis is most common in adolescents and young adults, and pneumococcal meningitis is most common in adults. Listeria meningitis generally occurs in people with damaged immune systems, especially those going through chemotherapy for treatment of cancer. Reproduction of meningitis
-The process in which N. Meningitidis reproduces is binary fission. Binary fission is one of the most common ways for...
