Recurrent streptococcal toxic shock syndrome due to distinct episodes of Streptococcus dysgalactiae and Streptococcus agalactiae septic arthritis.

Streptococcal toxic shock syndrome (STSS) is an uncommon disorder characterised by hypotension and multiorgan failure in the setting of streptococcal infection. Recurrent STSS is rare and has been due to recurrence of the same streptococcal species. Here, we present a case of a patient who developed recurrent STSS from a Streptococcus dysgalactiae right native joint septic arthritis and subsequently from a Streptococcus agalactiae left native joint septic arthritis.
