Group B Streptococcus Meningitis Associated with Acute Otitis Media in an Adult Patient.

BACKGROUND We present a case of Group B Streptococcus (Streptococcus agalactiae or GBS) meningitis in a non-pregnant woman that likely originated from acute otitis media. Although invasive Group B Streptococcal infections are increasing in the United States, GBS meningitis is still rare in non-pregnant adults. At the end, we discuss risk factors for this disease and data that suggest that invasive GBS infection is increasing in the adult and elderly populations of the United States.
