HIGHER BACTERIA 365 



abscesses in man. A considerable number of non-pathogenic 

 species have been described from air and water, some of which 

 are chromogenic. Howard, 14 in studying actinomyces isolated 

 from the central nervous system, found that it may be both 

 aerobic and anaerobic. He also found actinomyces in com- 

 mercial vaccines. * 



SACCHAROMYCES. 



The significance of the saccharomyces (yeasts) is largely 

 restricted to their power of fermenting sugars, and they are 

 of value in those arts requiring such fermentation. Few spe- 

 cies are known to be parasitic or to produce lesions in the ani- 

 mal body. 



SACCHAROMYCES FARCIMINOSUS. 



Synonyms. Cryptococcus farciminosus; Blastomyces far- 

 ciminosus. 



Place in nature. This organism is the cause of the disease 

 known as epizootic lymphangitis in horses. 15 It is found in the 

 lesions of this disease both between the cells in the plasma, and 

 partly enclosed in the pus cells. It measures from 3 to 4 /* in 

 diameter and in unstained preparations it can be seen with the 

 oil immersion. It has been placed in numerous classifications. 

 Tokishige 16 was the first to place it among the saccharomyces. 

 Rivolta described it in 1873. It can be stained with carbol 

 fuchsin and other dyes. The disease which it produces is 

 somewhat widely distributed in France, in Sweden (where it 

 is known as Norlander Rotz), in Russia, Italy, Egypt and 

 Japan. Pearson found it in the United States. This is im- 

 portant because the disease which it produces may be some- 

 what easily mistaken for farcy or skin glanders.
