 Meningitis - Wikipedia, the free encyclopedia
Meningitis is the inflammation of the membranes (meninges) covering the brain and the spinal cord, usually due to bacterial or viral infections elsewhere in body that has spread into the blood and into the cerebrospinal fluid (CSF).
Meningitis should be distinguished from the condition encephalitis, the latter of which is the inflammation of the brain itself.
In addition to meningeal inflammation, these cytokines are responsible for the fever, headache, and increased intracranial pressure present secondary to the formation of the purulent exudate and obstruction of CSF flow through the ventricular system as well as inhibiting resorption of CSF by the subarachnoid granulations.

Experimental models of bacterial meningitis have demonstrated that it is the presence of this inflammatory response in the subarachnoid space that leads to altered CSF dynamics and cerebral blood flow, changes in subarachnoid capillary permeability, obstructed CSF resorption, increased intracranial pressure, decreased cerebral perfusion pressures, and loss of cerebral autoregulation (2).
In prospective population-based surveillance for bacterial meningitis in the United States in 1986, H influenzae type b was found to be the single most common pathogen, responsible for 45% of cases, with an incidence of 2.9 cases per 100,000 population.
