Streptococcus suis peritonitis: case report.

A 45-year-old Thai man who presented with peritonitis was seen in a tertiary care centre in Thailand. An exploratory laparotomy was done because of peritonitis from abdominal trauma. Postoperatively the patient received intravenous ceftriaxone and metronidazole, but he developed rhabdomyolysis and acute renal failure. Hemodialysis was performed. After 8 days, the peritonitis had relapsed with hypotension. The patient was given vasopressives but clinicaly deteriorated and expired on day 11. The peritoniteal fluid culture grew Streptococcus suis serotype 2 and the organism was resistant to multiple antimicrobial agents including penicillin (MIC > 32 mcg/ml) but was susceptible to vancomycin.
