IDENTITY OF AMERICAN AND FRENCH SPOROTRICHOSIS 109 



now they can no longer be considered rare. Ruediger 9 

 gathered together and analysed all the cases in the United 

 States in 1912. He found 57 in which the diagnosis had been 

 made with reasonable certainty. Since then the literature 

 each year has furnished a considerable number of additional 

 reports. Many cases have no doubt not been recorded in the 

 literature. The writer is aware of several in which cultures 

 were obtained and identified as Sporothrix schcnckii but never 

 reported. 



Ruediger called attention to the interesting fact that the 

 disease occurred chiefly in the Missouri River Valley. Five- 

 sixths of the 57 cases were from this locality, the others 

 being scattered more or less diffusely over the country. North 

 Dakota, which furnished 22 authentic cases, seems to be the 

 chief focus of human infection in this country. Kansas has 

 also furnished a large number of cases. A map showing the 

 location of the cases in the United States accompanies Ruedi- 

 ger 's paper and brings out strikingly the geographical dis- 

 tribution. However, K. F. Meyer 10 has more recently analysed 

 the data, especially those dealing with the relation of animal 

 and human sporotrichosis in this country. He shows that 

 as new cases appear it becomes increasingly evident that the 

 disease is widely distributed, though certain localities like 

 the Missouri River valley furnish the great majority of the 

 cases. It has been reported from the following states : Mis- 

 souri, Kansas, Iowa, Nebraska, Texas, Virginia, West Vir- 

 ginia, Ohio, New Jersey, District of Columbia, South Dakota, 

 North Dakota, California, Illinois, Pennsylvania, New York, 

 Minnesota, Wisconsin, Indiana, Montana and Michigan. Two 

 cases have been reported from Canada. 



Sporotrichosis has appeared in horses in several localities 

 in the United States. The disease was recognized clinically 

 in horses some time before it was accurately studied bacter- 

 iologically in this animal. Horses were found in 1908 or be- 

 fore in North Dakota suffering from what was then taken to 

 be mycotic lymphangitis. From the description and the
