Diagnosis of nonviral infectious etiologies

In contrast to the viral causes of aseptic meningitis, nonviral causes of meningitis usually produce a more complicated course and always must be considered because they can be managed with specific treatments.

Consider partially treated bacterial meningitis, especially when the patient has a history of previous oral antimicrobial therapy and when CSF exhibits persistently low glucose or polymorphonuclear pleocytosis. Latex agglutination tests may be useful in these patients.
