A comparative study of staphylococcus haemolysins and Colisan.
Staphylococcus beta-haemolysin exhibits the same broad spectrum of antagonistic activity against smooth muscle stimulants as described recently for Colisan. The antispasmodic effect develops slowly and can be removed only by repeated washing. The pattern of haemolytic activities of Colisan is characteristically different from that of beta-haemolysin, but resembles closely alpha-toxin. Both staphylococcus toxins can destroy paramecium and entamoeba, but the ratio of the titres at which they kill paramecium and entamoeba respectively (P:A value) is different. The P:A value of beta-haemolysin is similar to that of Colisan.
