• One of the most useful phenotypic characteristics of streptococci is the hemolytic reaction, generally classified as alpha, beta or gamma according to the appearance of zones around colonies growing on Blood Agar
• Beta-hemolytic streptococci are further characterized by Lancefield groups based on the antigenic differences in group-specific polysaccharides located in the bacterial cell wall
