Acute peritonitis and salpingitis associated with streptococcal toxic shock syndrome caused by Lancefield group G α-haemolytic Streptococcus dysgalactiae subsp equisimilis

The authors treated a patient for what appears to be the first reported occurrence of acute peritonitis and salpingitis associated with streptococcal toxic shock syndrome (STS,S). This was caused by Lancefield group G alpha-haemolytic Streptococcus dysgalactiae subsp. equisimilis TKCH2004-001. The isolate showed M protein type stc36 and carried the spegg gene. To the best of the authors' knowledge, the present report represents the first case of STSS complicating acute peritonitis and salpingitis caused by Lancefield group G a-haemolytic S. dysgalactiae subsp. equisimilis.
