Meningitis is an infection of the meninges, which are membranes covering the brain and spinal cord. Any virus, bacteria, fungus, or parasites (really, any organism) that can infect the meninges could be a cause of meningitis.
Typically, meningitis is caused by viral infections that will usually get better without treatment. Bacterial causes of meningitis are extraordinarily serious and require immediate emergency medical treatment. Fungal causes of meningitis are much less common among individuals, and are usually seen in immune compromised individuals.
Common viruses that cause meningitis include: viruses from the Herpes family (the ones that cause cold sores, genital herpes, and chicken pox / shingles), viruses that cause the mumps, the West Nile Virus, enteroviruses (like Polio), etc.
Common bacteria that cause meningitis include: Neisseria meningitidis (part of the normal mouth flora of 5-15% of adults), E. coli (normal inhabitant of our digestive tract), Listeria monocytogenes (why mothers are often advised to avoid lunchmeat), strep. pneumoniae, Haemophilus influenzae (which is not what a flu vaccine is for), etc.
Of the bacterial causes, Strep Pneumoniae and Neisseria account for the majority of the cases.
No, tubercular meningitis is caused by the bacteria Mycobacterium tuberculosis, while bacterial meningitis can be caused by various types of bacteria. Tubercular meningitis specifically refers to meningitis caused by tuberculosis bacteria, while bacterial meningitis can be caused by a variety of bacterial species.
This is a type of meningitis caused by the bacteria spirillum serpens.
Meningitis is caused by a bacteria or a virus.
The scientific name for meningitis is "meningococcal meningitis." It is most commonly caused by a bacterial infection with the bacteria Neisseria meningitidis.
It means an inflammation of the meninges. The meninges are the covering of the brain and spinal cord. They can swell and harm the cord and the brain. It is very serious. It can be caused by a bacteria or a virus.
Viral meningitis is caused by a virus, while bacterial meningitis is caused by bacteria. Bacterial meningitis is usually more severe and can be life-threatening, requiring immediate medical attention. Viral meningitis is typically less severe and often resolves on its own with rest and supportive care.
Meningitis is an inflammation of the meninges, a protective coating in your body that defends your spinal nerves and brain. The inflammation is caused when some infection attacks the meninges. Meningitis is generally sorted into two main types: Bacterial and Viral. The difference, of course, being that one is caused by a bacterial infection, and one is caused by a viral infection. There aren't really any infections that specifically cause meningitis. It's normally caused by some other infection that works its way into the meninges. However, meningitis can also be caused by various fungi, parasites, allergies to drugs, chemicals, and tumors. Though these are much less common than the bacterial and viral variants.
Meningitis can be caused by different types of microbes, including bacteria (such as Streptococcus pneumoniae and Neisseria meningitidis), viruses (such as enteroviruses and herpesviruses), fungi (such as Cryptococcus neoformans), and parasites (such as Naegleria fowleri). The specific cause of meningitis can vary depending on the age of the individual, underlying health conditions, and other factors.

[From Wikipedia: http://en.wikipedia.org/wiki/Meningitis ]Meningitis is a medical condition that is caused by inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges.So meningitis is not single celled, because meningitis itself isn't a bacteria or virus, but the resulting swelling caused by any number of things; of which can be bacterial or viral.
