Meningitis Due to Mixed Infection with Penicillin-Resistant and Penicillin-Susceptible Strains of Streptococcus pneumoniae

摘要

Streptococcus pneumoniae is the major cause of bacterial meningitis. We report a case of meningitis due to a mixed infection with two distinct strains of S. pneumoniae: one penicillin-resistant strain of serotype 9V and one penicillin-susceptible strain of serotype 7. The two strains exhibited different pulsed-field gel electrophoresis profiles.
