Group A streptococcus (GAS)

Invasive GAS (IGAS) occurs when the bacteria proliferate in a normally sterile body site, such as the blood, soft tissues or joints. 

Streptococcal toxic shock syndrome (STSS) can be a severe complication of IGAS, caused by toxins that are produced by GAS, which act on host cells or tissues.
