Streptococcus agalactiae meningitis presenting withcerebral infarction in an adult patient: Clinical caseand review

[摘要] 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) iscommon for the neonatal period but is deemed to be rare in adult patients. Since 2000, more thantwo-thirds of all cases occur in adults, which is becoming a growing problem worldwide. We presenta rare case of GBS meningitis presented with cerebral infarction in an adult patient and briefly reviewthe etiology and incidence of GBS infections in adults. There is an increasing incidence of cases inelderly patients, particularly in those with more medical comorbidities. Cerebral infarction as an adverseeffect in bacterial meningitis is both a sign of severity and a predictor of a poor clinical outcome witha high mortality rate. Early recognition of the infection, a search for deep-seated infection, and earlyantimicrobial therapy are vital moments for successful management of the GBS disease.
