In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as âgroup A strepâ and âgroup B strepâ).
1 Beta-hemolytic species, including S. pyogenes and S. agalactiae, completely rupture the red blood cells (visible as a halo in culture). 2  Gamma-hemolytic, or non-hemolytic, species do not cause hemolysis and rarely cause illness.n vitro hemolysis during specimen collection can cause inaccurate laboratory test results by contaminating the surrounding plasma with the contents of hemolyzed red blood cells.
