Primary Bacterial Peritonitis Caused by Streptococcus pneumoniae.

Primary peritonitis is a rare infection in healthy children, mainly affecting patients with underlying medical disorders. We report a case of primary pneumococcal peritonitis in an immunocompetent 3-year-old boy. Diagnosis was made at laparotomy and cultures of the intra-abdominal pus yielded Streptococcus pneumoniae. Timely antibiotic treatment administered resulted in complete resolution of the infection.
