A case of fatal sepsis in a child due to highly resistant Streptococcus pneumoniae.

Infection with Streptococcus pneumoniae continues to be a significant cause of morbidity and mortality. Most of the pneumococci remain exquisitely sensitive to penicillin. However, S. pneumoniae with a reduced susceptibility to penicillin has been reported. To our knowledge, we present the first case in Croatia of fatal sepsis in a child due to Streptococcus pneumoniae that was highly resistant to penicillin.
