Bacterial Meningitis

Meningitis is an inflammation of the covering of the brain and spinal cord. It can be caused by viruses, parasites, fungi, and bacteria. Viral meningitis is most common and the least serious. Meningitis caused by bacteria is the most likely form of the disease to cause serious, long-term complications. It is an uncommon disease but requires urgent treatment with antibiotics to prevent permanent damage or death. Bacterial meningitis can be caused by multiple organisms. Two common types are Streptococcus pneumoniae, with over 80 serogroups that can cause illness, and Neisseria meningitidis, with five serogroups that most commonly cause meningitis.
