IDENTITY OF AMERICAN AND FRENCH SPOROTRICHOSIS 115 



Die Frage kann nur entschieden werden durch Vergleich der 

 Original-kulturen von Schenck und Hektoen. Entschliesst man 

 sich, diese dritte Hypothese einer Unitat des Sp. Schencki und 

 des Sp. Beurmanni anzunehmen, so wurde trotzdem die Tatsache 

 bestehen bleiben, dass dieser Parasit in zwei Typen sich darstal- 

 len kann; als Sp. Schencki, der seltener Typus, welcher einzig 

 von den amerikanischen Forschern im Jahre 1898 and 1900 be- 

 schrieben worden und von welchem der Stamm Hektoen-^Gou- 

 gerot eine Abart bildet (Sp. Schencki-Beurmanni var. Schencki), 

 und schliesslich als Sp. Beurmanni, ein sehr verbreiteter Typus, 

 der zum ersten Mai von Matruchot & Ramond im Jahre 1903- 

 1905 und spater im Jahre 1906 von Beurmann & Gougerot 

 studiert worden ist (Sp. Schencki-Beurmanni var. Beurmanni.) 



From the above statements it is evident that Gougerot him- 

 self concedes the identity of the French and the later Amer- 

 ican strains and I entirely agree with him on this point. I 

 have examined several French strains very carefully and 

 compared them with later American strains from man and 

 horses without noting any essential points of difference. Ad- 

 mitting then that the French strains and the later American 

 strains are identical, the question resolves itself into a com- 

 parison of the disease and organisms as observed by Schenck 

 and by Hektoen on the one hand and the French and later 

 American disease and organisms on the other. These latter, 

 it is to be noted, are conceded to be identical with the strains 

 from South America, Madagascar, and the other foci men- 

 tioned above. If it is shown that they are identical with 

 the Schenck-Hektoen strain, they should all be called Sporo- 

 trichum schenckii. If they are different, they would be called 

 Sporotrichum beurmanni and the strains of Schenck and Hek- 

 toen would remain as isolated and unique organisms differing 

 from all other described sporotricha. 



COMPARISON OF THE Two CASES OP SPOROTRICHOSIS OBSERVED 



BY SCHENCK AND BY HEKTOEN AND PERKINS WITH 



THE LATER AMERICAN CASES 



Clinically these two cases were typical ascending gumma- 

 tous sporothrichosis identical in every way with the many 

 cases observed later by the French and by many observers
