Definition of Meningitis - staphylococcal:

Staphylococcal meningitis is an infection of the membranes covering the brain and spinal cord (meninges), caused by Staphylococcus bacteria.

Causes, incidence, and risk factors:

Meningitis caused by Staphylococcus aureus or S. epidermidis usually develops as a complication of a surgical procedure, or as an infection spread by the blood from another site.
