are affected in a peculiar way, becoming swollen, tender, then 

 hardened and adherent. 



Acute cases. — In acute cases of respiratory glanders, small 

 tubercles or nodules develop rapidly on the mucous membrane 

 of the respiratory organs and soon change to small ulcers, which 

 increase in size and even coalesce. Thus is developed the 



peculiar ulcer of glanders, 

 with its dirty gray base 

 and overhanging edges. 

 Very large ulcers and even 

 ragged, gutterlike excava- 

 tions may develop, partic- 

 ularly on the nasal sep- 

 tum. The ulcers may 

 heal, leaving light-colored, 

 more or less star-shaped 

 scars. 



The fever may be severe 

 in acute glanders of either 

 type, the temperature ris- 

 ing rapidly to 105 or even 

 107, and then be quite 

 variable for a few days. 

 There may be also per- 

 sistent chills. 



There are also areas of 

 lung inflammation and 

 nodules in some cases. Oc- 

 casionally there is an ap- 

 parent recovery from the acute symptoms and then development of 

 a chronic case. This condition applies to both types of glanders. 

 Chronic cases. — If the disease be chronic, then in general the 

 symptoms develop less rapidly and the disease is slower and 

 milder. The chronic pulmonary form of glanders may be sus- 

 pected when there is a mild, dry cough, especially if such cough 

 be accompanied by debility and occurs in a stable where an 

 obvious case of glanders has been demonstrated. When the 

 lungs are much affected in chronic cases of pulmonary glanders, 

 the horse is apt to show symptoms of heaves, and on examination 

 post mortem there are found numerous tubercles, usually show- 

 ing, or easily felt, on the surface of the lungs.
