VAEIOLA VACCINA (COW POX). 



This disease, commonly known as cow pox, is more common 

 among cattle than any other class of animals. It is an eruptive 

 pustular disease, usually found in connection with the udder 

 (bag). 



Cause. It is caused by contagion, which exists only in the 

 fixed form. 



Symptoms. There is usually a slight fever, the flow of milk 

 is arrested, and the appetite is impaired. The skin of the udder 

 and teats presents a reddened appearance, and soon red patches 

 occur, known as papulae. This is the papular stage and lasts 

 three or four days. The papulae gradually take on the character 

 of vesicles, becoming filled with serum (a watery fluid), and, like 

 the vesicles in horse pox, are depressed in the center, as though 

 bound down. This stage is the vesicular or second stage of the 

 disease. The vesicles gradually become pustules, and the third 

 or pustular stage of the disease is now reached. As many as five 

 of these pustules may be upon one teat, and each the size of a 

 finger. 



Treatment. As a general thing but little treatment is neces- 

 sary. The animal should be fed upon food of a laxative nature. 

 Oreat care must be taken not to expose the animal to draughts 

 of cold air, taking cold, etc. If the teats are so sore as to be 

 very painful in milking, use the teat syphon, which should be 

 nicely oiled and gently passed up the teat, when the milk will 

 come away of itself. Anoint the sores on the teats and udder 

 nicely twice a day with carbolized vaseline. Separate the ani- 

 mals from other animals, and the milk should not be u-c<l. 

 The attendant should not be allowed to attend to animals un-
