Group A Streptococcus (GAS) is a gram positive bacteria that can cause a wide range of infections. Most GAS infections are relatively mild illnesses such as "strep throat," or impetigo (a skin infection). Occasionally these bacteria can cause severe and even life-threatening diseases such as bacteremia, toxic shock syndrome and necrotizing fasciitis.
