With aseptic meningitis a person has signs and symptoms of meningitis, but bacteria does not grow in cultures. Many different things can cause aseptic meningitis including viruses, fungi, tuberculosis, some medications and infections near the brain or spinal cord, such as epidural abscesses.
Most viruses causing viral meningitis can be isolated from the CSF (Klawans and Goetz 1978). Viral isolation from the throat, urine, and stool should also be attempted. A 4-fold rise in specific antibody in the convalescent serum specimen, or the intrathecal production of specific antibody, supports the diagnosis.
