[Severe infection from invasive beta-hemolytic streptococcus group A. Three cases of toxic shock observed in resuscitation].

Group A streptococci (GAS) may cause a variety of infections, some of which are severe and may be life-threatening. Patients affected by severe invasive GAS infections may develop, early in the course of the infection, a syndrome characterized by circulatory insufficiency with multiple organ failure: Streptococcal Toxic Shock-Like syndrome (Strep-TSLS). The presence of shock and organ failure differentiate it from other types of invasive GAS infections.
