IDENTITY OF AMERICAN AND FRENCH SPOROTRICHOSIS 113 



Animal susceptibility is rather general, the spontaneous 

 disease having appeared in man, horse, mule, dog and rat. It 

 has been observed as an accidental infection in man. Ex- 

 perimentally it has been produced in a large number of the 

 lower animals, the rat being probably the most susceptible and 

 useful animal for this purpose. 



A STATEMENT OF THE QUESTION 



At their request, Hektoen in 1906 sent to de Beurmann and 

 Gougerot at Paris a culture of the American organism which 

 he had isolated seven years before. After studying and com- 

 paring this organism with their strains they declared that the 

 American and French strains were different and they con- 

 tinued to retain the name of Sporotrichum beurmanni for the 

 French fungus and to use the term Sporotrichum schenckii 

 for the North American strains. It is to be noted, too, that 

 de Beurmann and Gougerot and their French colleagues con- 

 sidered the South American strains, the Madagascar strains, 

 the German, Austrian and other strains, all of which were 

 described after their work, as identical with the French 

 organism. 



In 1910 the writer took to Gougerot in Paris a strain iso- 

 lated by himself from a tj^pical human case from North Dakota 

 and reported later by Hyde and Davis. 17 I received from 

 him and also from Sabouraud at that time strains isolated 

 from cases in France and called by them Sporotriclium beur- 

 manni. I also obtained from Hektoen a culture of his sporo- 

 trichum which he had preserved from his case of 1899, a 

 culture of which, as stated above, he had sent to de Beur- 

 mann and Gougerot in 1906. De Beurmann, Gougerot and I, 

 therefore, have French strains, American strains and the 

 original Schenck-Hektoen strain for comparison. In order 

 to simplify and limit the discussion as far as possible I will 

 make the following statement : first, excluding for the time 

 being the Schenck-Hektoen strains, we may consider all the 

 later strains, except Sporotrichum councilmans, isolated in
