Streptococcus pyogenes meningitis:: report of a case and review of the literature

Streptococcus pyogenes is a very uncommon cause of bacterial meningitis beyond the neonatal period. A case report and a review of the recent literature is presented. We report on a previously healthy 7-year-old boy who developed S. pyogenes meningitis following a 2-day history of otitis media. A CT scan revealed right-sided mastoiditis as a possible focus of infection. The patient was treated with penicillin G for 14 days. The clinical course was uneventful, and he recovered without sequelae. By means of the polymerase chain reaction, the presence of streptococcal pyrogenic exotoxin (SPE) B and SPE C, but not SPE A genes was discovered from the bacterial DNA. Conclusion Streptococcus pyogenes is a rare cause of bacterial meningitis but has to be considered as the causative pathogen beyond the neonatal period.
