Group A streptococci when grown on blood agar typically produces small zones of beta-hemolysis, a complete destruction of red blood cells. (A zone size of 2–3 mm is typical.) It is thus also called group A (beta-hemolytic) Streptococcus ( GABHS ), and it can make colonies greater than 5 mm in size. Examples: Streptococcus pyogenes, or Group A beta-hemolytic Strep (GAS). Weakly beta-hemolytic species: Streptococcus agalactiae, Clostridium perfringens, Listeria monocytogenes.
