In the last issue1 of The Journal occurs a full extract of Moser's recent report of his work on the treatment of severe cases of scarlet fever with a serum obtained from horses immunized with cultures of streptococci isolated from the blood of fatal cases of scarlatina. Moser assumes that the streptococci so commonly associated with scarlet fever, especially in severe and fatal cases, differ sufficiently from other streptococci to warrant the effort at manufacture of a special serum for therapeutic purposes with the special streptococci of scarlatina.
The use of ordinary streptococcus serum made by Marmorek not having any material influence on the course of severe scarlatina appeared to Moser to be an additional reason for this attempt. Hence horses were immunized with mixtures of the cultures of streptococci obtained from fatal cases of scarlet fever, and the serum thus obtained was used in severe cases of the
