This incomplete hemolysis is called alpha (α) hemolysis. “ on prolonged incubation, many alpha hemolytic organisms will begin to appear more clear, but if the surrounding medium contains any shades of brown or green the ‘hemolysis’ is still considered ‘alpha.’” (buxton, 2005). Beta hemolysis is complete hemolysis. it is characterized by a clear (transparent) zone surrounding the colonies. staphylococcus aureus, streptococcus pyogenes and streptococcus agalactiaeare b hemolytic (the picture on the right below shows the beta hemolysis of pyogenes). partial hemolysis is termed alpha hemolysis.
