The common pathogens of pediatric septic meningitis are S. meningitidis, Escherichia coli, Staphylococcus aureus, and Staphylococcus epidermidis. Meningococcal infections often develop in the spring and cause meningitis, also known as rheumatoid encephalitis. Antibiotics may be applied in the early stages of the disease because of fever. When symptoms of meningitis occur, positive culture results are rarely done, and doctors often choose a broad-spectrum antibiotic, i.e. one that can cover both negative rods and positive cocci, depending on the situation, and need to consider the ability of the drug to cross the blood-brain barrier for treatment. A cerebrospinal fluid test is usually needed to help with the diagnosis, and the cerebrospinal fluid needs to be rechecked 1-2 weeks after treatment to see the effect of the treatment.
