Staphylococcus aureus meningitis

Meningitis caused by Staphylococcus aureus is mostly secondary to S. aureus sepsis, especially in patients with left endocarditis, which invades the meninges through the bloodstream of bacterial emboli. Facial condyles complicated with cavernous sinus thrombophlebitis can further lead to meningitis. Meningitis can also be complicated by craniocerebral injury, inadequate disinfection after craniocerebral surgery, and lumbar puncture. Infectious lesions near the meninges such as otitis media, mastoiditis, and sinusitis can also cause the disease. Meningitis can also be secondary to staphylococcal aureus infection in the umbilical cord and skin of newborns, and the onset time is mostly about 2 weeks after delivery. Other susceptible factors are: diabetes, intravenous drug abuse, hemodialysis, and malignant tumors.
