226 GLANDERS AND ACTINOMYCOSIS. 



myces, presenting the same branched forms, clubs, spore-like 

 bodies, and filaments. It also stains like the actinomyces. 

 Most authorities are inclined to regard the Streptothrix madurce 

 and the Streptothrix actinomyces as separate species, but there 

 are so many points of similarity between the conditions pro- 

 duced by them that one is justified in assuming that Strepto- 

 thrix madurce is simply a variation of the actinomyces, such 

 variation being due to conditions which influence the growth 

 of the organism. 



Farcin du Boeuf; Streptothrix Farcinae. 



This is another disease caused by an organism which 

 resembles the actinomyces. 



The exciting cause is Streptothrix farcinae or the bacille du 

 farcin des boeufs Nocard. 



The disease is one of cattle, and is never seen in man. 

 Pathologically it is an intense inflammation of the lymphatic

structures, especially the lymph-glands in the axilla? and 

 those at the root of the lung. The glands are considerably 

 enlarged, and finally break down, discharging a creamy pus. 

 The specific organism is found in the centre of the lesion. 

 It consists of very long, slender filaments, which branch 

 freely and contain spore-like bodies (Fig. 92). It is strongly 

 aerobic, and grows best at the temperature of the body. It 

 is stained by Gram's method, and also with the ordinary 

 anilin dyes.
