FARMER'S CYCLOPEDIA OF LIVE STOCK 



The best prevention of anthrax consists 

 in the use of a vaccine from which good 

 results have been obtained by the Bu- 

 reau of Animal Industry and by other 

 investigators. In some localities in the 

 South this disease is almost stationary 

 and has to be treated constantly by the 

 preventive method. 



Glanders, also called farcy or nasal 

 gleet, is a malignant, highly contagions 

 disease due to infection with the gland- 



Glanders occurs under at least three 

 distinct forms, one affecting chiefly the 

 lungs, another the nasal passages and 

 the third the skin. These forms of the 

 disease, however, are not by any means 

 separate and distinct, but the most con- 

 spicuous symptoms may be located in 

 one or the other of the sets of organs 

 just mentioned. In pulmonary gland- 

 ers, for example, the lungs are the chief 

 seat of infection and contain tubercles

ers bacillus. Glanders is most common 

 in horses and in mules, but may occur 

 in nearly all the domestic animals ex- 

 cept cattle. Man may also become in- 

 fected through wounds, . and in such 

 cases the disease is nearly always fatal. 

 Likewise in horses the disease is almost 

 uniformly fatal, but the course may 

 vary from a few weeks to several years. 



of varying size, depending on their 

 age. At first these tubercles are so 

 minute that they would not be detected 

 except by the trained veterinarian. 

 Later, however, they increase in size, 

 break down and pockets are thus formed 

 which contain pus; such pockets are at 

 once disclosed by cutting through the 

 lungs with a sharp knife.
