ContagioiLS Cellulitis is a highly contagious acute fever of the 

 horse, which has been generally ignored except by British veter- 

 inary writers, although it .seems to be widely distributed in vari- 

 ous countries. It is common in parts of America, but fre- 

 quently confused with influenza or catarrhal fever, although 

 wholly distinct. 



We in.sert an account of this disease here becau.se of its inti- 

 mate bearing upon the question of horse breeding, which it affects 

 chiefly in three distinct ways. 



It is frequently spread from apparently healthy stallions to 

 mares through copulation, in which respect it approaches the 

 character of a venereal di.sease, although, as a general rule, this is 

 not the method by which it is transmitted from animal to animal. 



It has a relation to sterility becau.se it causes an orchitis in 

 the stallion, which frequently leads to a permanent loss of func- 

 tion in the.se glands. 



It is related to abortion in that it very frequently cau.ses the 

 death of the fetus in utero when affecting the pregnant mare. 



Symptoms. The symptoms of the di-sease consist primarily of 

 an elevation of temperature, sometimes accompanied by chills, 

 dullness and other phenomena, which belong in general to acute 

 contagious fevers. The fever appears very suddenly, usually 

 ranging from 103 to 105° F. although it may exceed this. Gen- 

 erally speaking, the temperature is higher than in influenza and 

 lower than in the contagious pneumonia of the horse. The 

 pulse is hard and full and somewhat quickened, while the res- 

 piration is not very greatly disturbed. Some cough is present, 

 though this does not constitute a very prominent symptom of 

 the affection.
