title: [Streptococcal Toxic Shock-like Syndrome due to Streptococcus suis Serotype 2 in a Japanese Pig Farmer].
abstract: Streptococcus suis is a major swine pathogen. It has recently been recognized as an emerging zoonosis that causes mainly meningitis and sepsis in human. In particular, toxic shock-like syndrome (TSLS) caused by this pathogen has a high mortality rate. However, misidentification of S. suis by conventional biochemical and commercial identification tests is not rare. The patient was a 71-year-old man who worked as a pig farmer who was admitted for fever, oliguria and subcutaneous hemorrhage. He was diagnosed as having septic shock and blood culture was positive for Gram-positive cocci, mainly diplococcus. This pathogen was identified with S. suis with using MALDI-TOF MS analysis, though a commercial Gram-Positive bacteria identification kit revealed viridans streptococci. His clinical features met the diagnostic criteria of TSLS, and ceftriaxone and clindamycin were administered. On admission day 28, he was discharged in good condition.
