358 The Diseases of Animals 



When an outbreak of a transmissible disease occurs 

 among animals, the well ones should be removed from 

 the sick and placed in uninfected quarters. Well animals 

 should never be left in infected stables and yards. 

 Medicinal treatment in most contagious diseases is of 

 little value. Vaccination or inoculation against them 

 is very effective in some cases, and the use of anti- 

 toxin, or blood serum, from immune animals, gives 

 excellent results in others. Some kinds of antitoxins 

 are now to be had as laboratory products. 



In treating animals sick with a transmissible disease, 

 every effort should be directed toward making the 

 subject comfortable and keeping up the strength, which 

 will enable it to overcome the disease. In guarding 

 against such diseases, quarantining is the most effec- 

 tive method. Animals suffering from a contagious 

 disease readily infect others, either by direct contact, or 

 indirectly by means of infecting quarters, pastures, 

 drinking places, food or other materials. In adding 

 new stock to herds, precautions should always be taken 

 to prevent the introduction of disease. 



GLANDERS AND FARCY 



Glanders and farcy are the same disease, farcy being 

 the form which attacks the skin. Glanders is a malig- 

 nant, infectious disease, caused by a germ (Bacillus 

 mallei) that attacks horses, mules and asses. It can 

 be transmitted to other animals by inoculation, but it 

 rarely occurs except in man, who may become inoculated 

 from glandered horses. The virus, or germ, of glan-
