Alleged Poisonous Properties. 



[OCT., 



Epizootic Lymphangitis is a contagious and eruptive disease, 



caused by the Cryptococcus farciminosus. Horses and mules 



are affected ; the ox is also susceptible, but 



Epizootic seldom takes the disease under natural 

 Lymphangitis. 



conditions. 



Symptoms. — The eruption appears on the legs, the neck, the 

 head, or any part of the body. U sually it starts near a wound 

 through which the microbe has en ered the tissues, but the 

 ulcers often do not appear /or mo 'ths after the wound has 

 healed. The lymph vessels in the skin stand out prominently, 

 and small hard nodules about the size of a hazel-nut appear on 

 their course. These nodules suppurate and discharge a thick 

 yellowish pus. Proud flesh grows from the wounds, the lymph 

 vessels around become inflamed, and the eruption gradually 

 extends. A thick yellow scab may form over a patch of ulcers. 

 The neighbouring glands are swollen and hard. The ulcers heal 

 with, difficulty, even under treatment, and they may break out 

 again after an apparent cure has been effected. 



The ulcers may ap^uai inside the nostrils, uui diis is not nearly 

 so common as in the case of glanders. In epizootic lymphangitis 

 the glands under the jaw may also be enlarged, as in the former 

 disease, and a discharge may appear at one or both nostrils. 

 If taken in the early stages this disease is curable, but after an 

 advanced stage is reached, treatment ; s hopeless. In the latter 

 case the animals emaciate, and may die of exhaustion. 



This disease is distinguished from farcy (glanders) by the 

 presence of the Cryptococcus in the pus, and failure of the 

 mallein test to produce a reaction. Both glanders and epizootic 

 lymphangitis may be present in the same animal. 



On post-mortem examination one usually sees little beyond 

 what is seen during life, but occasionally abscesses are found in 

 the internal organs.
