bacillus produces a small nodule (Fig. 90), which somewhat

 nodule. 



In the horse the disease first manifests itself by the forma- 

 tion of small ulcers on the nasal mucous membrane and an 

 excessive discharge of nasal mucus. The submaxillary and 

 other lymph-glands soon become enlarged and suppurate.

The disease may extend from the nose to other parts of the 

 body, especially the lung. 



The chronic form of the disease which affects the body 

 generally is called farcy. It is characterized by the formation 

 in different parts of the body of small circumscribed swellings, 

 known as farcy buds. These finally suppurate and form 

 ulcers, which discharge quite freely. 



Infection : In man the skin is the most frequent portal of 

 entry for the infection. An abrasion is always necessary. 

 Infection may also occur through the mucous surfaces. Cases 

 are on record where hostlers drank from the same pail as a 

 horse affected with glanders, and acquired the disease. It is
