In subacute glanders a chronic discharge from the nose is 

 usually the first thing noticed. It is of the same character as 

 that in the acute only not so exaggerated. The case runs along 

 with no other symptoms except the discharge and the enlarge- 

 ment of the submaxillary lymphatics. Such a case may keep up 

 indefinitely if well cared for. But during all this time the horse 

 is sowing the germs of the disease everywhere he goes. The 

 termination of a chronic case is a sudden development of the 

 acute form. This comes from exposure such as an animal would 

 get on board ship or in the army, or even poorly ventilated stables 

 may be a cause or hardship of any kind, exposure to a cold storm, 

 etc. 



Acute Farcy. — This form of glanders starts with abscesses 

 in the lymphatics. They begin as small nodules about the size 

 of a hazel nut and suppurate, rupture, discharge and ulcerate. 

 The legs swell and eventually the eruption involves the greater 

 portion of the body. The condition grows worse rapidly and after 

 2-4 weeks the case runs its course and acute glanders develops. 



Chronic Farcy. — In a mild form the inflammatory areas on 

 the leg become indurated while small nodules spring up in other 

 parts. The course is slow. Many of the ulcers heal, leaving 

 hairless scars. Sometimes the farcy buds come up on the head 

 and neck pretty thick ; they heal and leave scars. Such a case 

 may continue for years until some unfavorable condition develops 

 to produce a severe exacerbation. 



Besides the conditions previously mentioned, severe purgation 

 may bring on a sudden development of acute glanders. In this 

 climate chronic glanders runs its course in about 3 years, but in 

 North Dakota and Montana it may run along for 10 years or 

 more. 



How IS the disease carried? The usual port of entrance is 

 thought to be the alimentary tract. The virus may be absorbed 

 from any mucous surface or through any abrasion of the skin. 

 Feed boxes, drinking places and hitching posts are sources of in- 

 fection. A glandered horse is prone to rub his nose and the 

 sticky discharge therefrom contaminates everything it comes in 

 contact with. Dogs discharge much more freely than the horse. 

 They carry the glanders germs from one place to another.
