The production of a toxin by Streptococcus hemolyticus isolated from the blood of patients with puerperal fever has been demonstrated.1 A comparison of the toxin with that produced by the specific Streptococcus hemolyticus of scarlet fever2 by means of the skin test3 was considered of interest.
The pathologic condition in puerperal fever produced by Streptococcus hemolyticus is the same as that of any hemolytic streptococcus infection elsewhere in the body.
Thus, the various strains of the streptococcus, as those of erysipelas, scarlet fever or any septic focus, may produce the same picture, except in the case of the scarlet fever strain, which may also produce a scarlatinal rash. This similarity of pathologic pictures was first observed by Semmelweis in the necropsy of his friend Kolletschka, who died from a septic infection in his finger incurred during a postmortem, and in the large number of necropsies of the
