Summary
Streptococcus pyogenes (group A Streptococcus; GAS) causes life-threatening invasive infections including flesh-eating disease and toxic shock syndrome (>600,000 cases and 163,000 deaths per year). We recently discovered the trigger for invasive disease in a globally disseminated GAS strain. The aim of this work is to determine whether this trigger applies to other strains associated with GAS invasive disease. These studies will allow the development of new therapeutics and treatments.

Summary
Streptococcus pyogenes (group A streptococcus, GAS) is estimated to cause ~700 million cases of self-limited throat or skin infection each year worldwide. Invasive GAS disease occurs in approximately 1-1000 cases, with associated mortality of 25%. We have recently discovered that a viral infection can reprogram GAS for invasive disease propensity. We will investigate whether this phenomenon is widespread, in order to understand this process and develop future therapeutics.
