and is finally unserviceable. Localized suppurative areas 

 in the region of lymphatic glands may appear eventually. 



Acute glanders. Acute glanders is, luckily, very rare. 

 Its diagnosis, clinically, presents difficulties. An attack 

 of acute glanders does not differ materially from an 

 attack of strangles in a serious form. Possibly the symp- 

 toms in acute glanders are slightly more vicious from the 

 very beginning. 



There is an occasional diagnostic feature, namely, the 

 appearance of blood in the nasal discharge. A suspected 

 case of strangles should be considered as glanders when- 

 ever the nasal discharge is streaked with blood. This 

 symptom does not occur in all cases of acute glanders, 

 but when it does occur, it is quite reliable. 



Now and then a ease of chronic glanders may become 

 acute as a result of an overwhelming elaboration of toxins, 

 to which the already lowered resisting power of the horse 

 offers but little impediment. Such an occurrence is not 

 so difficult to recognize as a primary acute attack of 

 glanders. It is also well to suspect as acute glanders any 

 malignant form of strangles, or what appears to be 

 strangles, in horses that are over six years of age. 



Farcy, or localized glanders. When a glanders infec- 

 tion confines its activity to a circumscribed area of super- 

 ficial tissues, it is called farcy. The most frequent local- 

 ization of a glanders infection is in a pelvic limb. The 

 manifestation at first somewhat resembles "grease-heel." 

 There is fuUness and thickening of the integument, and 

 one or more areas of ulceration. These areas begin as a 

 "bud" or node ; they break down and remain as a crater- 

 like area, of a mouse-eaten appearance. Some may heal 

 over, while at the same time others appear; or subse- 

 quently others make their appearance higher up on the 

 limb, preferably ia the seat of the popliteal lymphatics. 

 Cord-like "runners" or swellings radiate from the ulcer
