TUBERCULOSIS 161 



disease and from local anthrax of the mouth and 

 pharynx. 



It must be remembered that the blood of an in- 

 fected animal is the medium of infection and also 

 that while the bacilli themselves are comparatively 

 easily destroyed, that the spores are extremely re- 

 sistant to the action of disinfectants: The gastric 

 juice has no effect upon the spores of anthrax, 

 although it is bactericidal for the bacilli themselves. 



Symptoms. — Suddenness of attack, high fever, 

 dyspnea, violent intestinal disturbances, hemorrhages 

 from all the natural openings of the body, the local 

 manifestations in the mouth and pharynx — saliva- 

 tion, the presence of vesicles on the mucous— mem- 

 brane, swelling of the throat, cyanosis, are all 

 indicative of this disease. The diagnosis is com- 

 pleted by the microscopical examination of the blood 

 and the identification of the Bacillus anthracis. 

 ^--Treatment. — Needless to say, suspected cases 

 should be handled with extreme caution, as the 

 disease is communicable to other animals and man. 

 All blood and discharges should be carefully dis- 

 infected and the carcasses should be cremated. At- 

 tempts ta cure the patient are futile. 



Tuberculosis 



Tuberculosis is not a common disease of the 

 dog, but cases do occur and such can nearly always 

 be traced to infection from mankind. It has been 

 amply proved that the patient becomes infected by 

 inhaling the dust from a room inhabited by a tu- 

 berculous person, or by licking up tuberculous spu- 

 tum or from eating food from the plate of a person 

 afifected with tuberculosis. 



Symptoms. — Usually the disease assumes the as- 

 pect of a chronic pneumonia or a chronic bronchial
