Invasive Streptococcus pseudopneumoniae infection in an adult patient with acute community-acquired meningitis: a case report.

Abstract

Rapid identification of pathogens in acute meningitis is critical for timely treatment. However, traditional methods often face limitations in differentiating closely related species such as Streptococcus pneumoniae and Streptococcus pseudopneumoniae. We report a case of community-acquired meningitis caused by S. pseudopneumoniae secondary to a cerebrospinal fluid fistula, highlighting the microbiological diagnostic challenges.
