THE VETERINARY SCIENCE 



lowing them up may take the germs into the lungs by eating 

 or drinking out of the same pail or manger, or off the grass 

 where the diseased cattle have been. In this manner the 

 disease is communicated from one to the other. These germs 

 may also pass out of the system into the milk, and animals 

 or people that drink the milk are liable to take the disease. 

 The danger of having a diseased cow around is therefore 

 apparent.

Symptoms. — At first the disease comes on very slowly 

 after the germs are taken into the system. If affecting the 

 lungs there is a short, dull cough which may be noticed more 

 in the morning, after exercise, or drinking. Later on the 

 cough becomes more troublesome, the animal runs down in 

 condition, the breath has a bad smell, there is a dribbling of 

 saliva from the mouth, the animal becomes hide bound, the 

 hair stands out and it is a pitiful looking sight. In a few 

 months the patient pines away and dies. The time it takes 

 the disease to run its course varies from three months to a 

 year. 



It is noticed more in thoroughbred than in grade cattle. 

 If affecting the bowels the animal runs down in condition, 

 has diarrhoea sometimes, then costiveness, changing every 

 few days. The other symptoms are the same, only when not 

 affecting the lungs there is not such a cough.
