Mixed bacterial meningitis due to Streptococcus pneumoniae and Neisseria meningitidis in an 18-month-old child.

We report an unusual case of culture-proven pneumococcal and meningococcal mixed meningitis in an 18-month-old girl. The patient responded well to antimicrobial therapy and recovered completely without sequelae. No underlying condition could be demonstrated except a rhinitis of unknown etiology 2 days before the onset of the symptoms suggesting meningitis.
