Medical Definition of A' haemolysis

1. Haemolysis observed infrequently in blood agar cultures of occasional strains of streptococci; the zone of haemolysis about the colony is not as clear, or wide, or distinctly outlined as it is in b haemolysis; there are a few apparently intact erythrocytes throughout the zone, but they are more numerous in the immediate vicinity of the colony, and there is no discoloration as there is in a haemolysis; the unique feature is that the zone becomes wider, i.e., the process is stimulated, when the culture is incubated at refrigerator temperatures (not true for b haemolysis); some strains of streptococci that are a'-haemolytic on horse blood agar cause typical a haemolysis on rabbit blood agar.
