[Primary peritonitis caused by Streptococcus pneumoniae].

Primary peritonitis caused by Streptococcus pneumoniae is a rare but serious complication of childbirth. We present here three cases of young women who developed abdominal pain after childbirth. All of the patients had fever with abdominal pain, diarrhea and clinical signs of peritonitis. In two cases a laparotomy was performed to remove pus. Cultures taken were positive for Streptococcus pneumoniae. Culture of vaginal swabs and blood cultures were also positive for the same pathogen. For the third patient, both vaginal swabs and blood cultures were positive for Streptococcus pneumoniae, antibiotic therapy only was administered. Outcome was favorable for all. We discuss the pathogenesis, clinical presentation, management and the usefulness for systematic search "for" Streptococcus pneumoniae in vaginal swabs.
