50 IVIASTITIS OF THE COW 



goes severe atrophy following pressure of the interstitial 

 connective tissue, which undergoes a high grade of pro- 

 liferation with induration or sclerosis of the part. 



Treatment. — Prophylcuris. — The danger of infection 

 in these cases is a very great one. Udder-streptomycosis, 

 especially the acute type, can pass through a cow stable 

 like a high-grade enzootic disease. Therefore, isolate the 

 diseased cow from the others and milk her last, and of the 

 quarters of the udder, milk the diseased one last of all. Do 

 not draw the infected milk upon the floor, but into a recep- 

 tacle of disinfectant with the idea of preventing the further 

 spread of the infection. 



The treatment proper is divided into treatment of the 

 general condition and treatment of the local condition. 



Treatment of the General Condition. — Fever is treated 

 with febrifuges. Camphor, five grains daily, is especially 

 recommended, because it is excreted with the milk and can 

 thus bring about local disinfection. If the milk of the other 

 quarters is to be used, some other febrifuge must be em- 

 ployed, such as antifebrin ( acetanilid ) , which does not 

 impart its taste to the milk. 



If the impaction secondary to fever is severe a purgative 

 of Glauber's salts is given. 



Treatment of Local Condition. — One should milk out 

 the infected quarter carefully. Then inject from 300 to 

 500 c.c. of lukewarm, previously boiled 4 per cent, solu- 

 tion of boric acid, which exerts a deleterious eff'ect upon 

 the growth of the bacteria without too much irritation to 

 the udder tissue. This solution can remain in the udder 

 without danger and can be milked out in about four hours 

 (Bigoteau). 



Externally one can use a mild skin irritant, as concen- 

 trated iodine solution, rubbed on daily for a day or two. 

 This stimulates an acute counter inflammation and 

 resorption.
