1. Explain the differences between bacterial meningitis, aseptic meningitis, fungal meningitis, and tubercular meningitis. Bacterial meningitis is a primary infection of the pia mater, arachnoid and subarachnoid space, ventricular system and the CSF of the brain. The subarachnoid space is accessed either by a systemic, bloodstream or direct extension infection. Common causes of bacterial meningitis after the neonatal period are Meningococcus (Neisseria meningitidis) and pneumococcus (Streptococcus pneumonia). For neonates, pneumococcus and gram-negative enteric bacilli are common agents. Aseptic meningitis (viral meningitis, nonpurulent meningitis, lymphocytic meningitis) is an inflammation which is thought to be localized to the meninges. The population at risk depends of the virus. A variety of symptoms are caused by a plethora of viruses such as enteroviral (most common), mumps, herpes simplex types 1 and 2,, St. Lus encephalitis virus, West Nile virus, California encephalitis virus, Venezuelan equine encephalitis, Colorado tick fever, lymphocytic choriomeningitis virus, Epstein-Barr virus, and influenza virus types A and B. Fungal meningitis is a chronic, much less common condition than bacterial or viral meningitis. It most frequently occurs in persons with impaired immune systems or those with altered normal flora. Development is insidious and usually occurs over days to weeks. Also associated with chronic meningitis are syphilis, tuberculosis and Lyme disease. Tubercular meningitis is the most common and most serious form of CNS tuberculosis, and is found mostly in those with acquired immunodeficiency syndrome (AIDS). Miliary tubercules form in the brain and meninges, later eroding in the...
