Streptococcus agalactiae meningitis presenting with cerebral infarction in an adult patient: Clinical case and review

Abstract

Bacterial meningitis is an inflammation of the meninges associated with the invasion of bacteria. The etiologic agents vary by age group. Bacterial meningitis due to group B streptococcus (GBS) is common for the neonatal period but is deemed to be rare in adult patients. Since 2000, more than two-thirds of all cases occur in adults, which is becoming a growing problem worldwide. We present a rare case of GBS meningitis presented with cerebral infarction in an adult patient and briefly review the etiology and incidence of GBS infections in adults. There is an increasing incidence of cases in elderly patients, particularly in those with more medical comorbidities. Cerebral infarction as an adverse effect in bacterial meningitis is both a sign of severity and a predictor of a poor clinical outcome with a high mortality rate. Early recognition of the infection, a search for deep-seated infection, and early antimicrobial therapy are vital moments for successful management of the GBS disease.
