Contagious Diseases and Their Suppression. 263 



especially if the herd is made up of pure-bred stock. 

 The tuberculin test, it should be remembered, is not in- 

 fallible. Thorough disinfection of stables should never be 

 neglected when tuberculosis has made its appearance; the 

 fact of its contagious nature must never be forgotten ; the 

 probable danger to human beings can best be limited by 

 the tuberculin test followed by Bang's method, pasteur- 

 ization of milk and thorough meat inspection. Prof. 

 Koch (Berlin) has recently stated that human tubercu- 

 losis cannot be communicated to cattle, and while not 

 fully proven, is of the opinion that tuberculosis cannot be 

 given by cattle to the human being; he asserts the great 

 danger lies in infection by the sputum of man; be it all 

 as he states tuberculous cattle are not as good property as 

 non- tuberculous cattle. 



Glanders and Farcy hold a somewhat similar position to 

 horses that tuberculosis does to cattle, although not as 

 common as that disease, yet is quite contagious, and in 

 the early stages hard to detect, in which case the use of 

 the mallein test is useful to detect the earliest inroads of 

 the glanders germ, the bacillus mallei. This disease is 

 transmissible to man, in whom it manifests itself by loath- 

 some symptoms. The symptoms, when the disease is far 

 enough advanced, in horses are as follows: A discharge 

 from one or both nostrils, usually from the left one, of a 

 sticky, green, gluey nature, with a discharge from the 

 eyes and enlargement of the submaxillary gland found 

 beneath the jaws; in the local form, termed Farcy, little 

 lumps form on the limbs and body, which eventually 

 break and discharge pus. Treatment of this disease is 

 not advisable, in fact under the contagious diseases acts
