Hemolysis (e.g. α, β, or no hemolysis with other colony characteristics) on sheep blood agar aids in presumptive identification, particularly of streptococci and enterococci. It is critical to decide whether true hemolysis is present or whether the discoloration of the medium is due to the organism’s growth on the plate. To visualize the hemolytic pattern, the colony is often removed with a loop. To decide if the organism is hemolytic, proper technique necessitates the passage of bright light through
