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 schencku 
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 typical human case from North Dakota 
and reported later by Hyde and Davis.*7 I received from 
him and also from Sabouraud at that time strains isolated 
from cases in France and called by them Sporotrichum beur- 
manu. 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 councilmani, isolated in 
N Jour. of Cut. Dis., 28, p. 321, 1910.
