      abstract = {Streptolysin S (SLS) is the most potent hemolysin known  (14). It is the oxygen-stable hemolysin (104) made by Group  A, C, E, G, H, and L streptococci (39). It differs from  streptolysin O (SLO) in that 1) the activity once lost  cannot be regenerated by reducing agents (48) (15), and 2)  it is not antigenic (39). No special substances are  required for SLO production (10), but SLS formation depends  upon the addition of any of several different substances to  the growth media or to harvested cells. The role of these  additives on SLS formation or production is uncertain. A  brief history of SLS will be presented to illustrate the  dependence of SLS upon these additives and to present a  nomenclature of SLS.},
