TREATMENT OF CHOLERA 227 



far as we know, that will take this disease. The virus which 

 produces cholera is unable to gain a foothold in the body of any- 

 other of the common animals found on the farm, and so we never 

 find cholera attacking the horse, the ox, the sheep, or man. There 

 is a great deal of resemblance between cholera in swine and typhoid 

 fever in man. Both diseases are marked by the occurrence of 

 ulcerations in the bowel, diarrhea, and profound prostration, but 

 the two diseases are not the same, and neither can be transmitted 

 from man to the hog, nor from the hog to man. 



Accordingly, it is often hard to get the stock-owner to see 

 wherein there can be any danger in allowing his hogs to eat the 

 carcass of a dead horse or a dead cow. They will willingly do so, 

 they seem to enjoy the meal, and it certainly saves him a lot of 

 extra work, and especially is a convenience if the animal happens 

 to die during the busy season. These animals do not have cholera, 

 and so cannot cause cholera to break out in the hogs, so what 

 danger can there be in allowing the hogs to have the feast they will 

 enjoy so well? 



There are a number of very good reasons why you should 

 never allow a dead animal carcass of this kind to be disposed of in 

 this manner. While it is all very true that the other farm animals 

 do not have cholera, and cannot directly produce cholera in hogs, 

 there are numerous indirect ways in which they may, and often do, 

 lead to the development of cholera in the animals which are allowed 

 to eat their dead bodies. 



In the first place, in connection with cattle, a large percentage 

 of the dairy cows on our farms are affected with tuberculosis, and 

 it is a pretty safe estimate to say that nearly half of the cows 

 which die on the farm either die from tuberculosis or have effects 

 of this disease in their body. Now this disease is directly trans- 

 ferable from cattle to hogs, and if the hogs are allowed to eat the 

 carcass of an animal that has died from tuberculosis they are 

 almost certain to themselves develop the disease. 



In nearly every dead body of any animal that may die on the 

 farm there are present some disease germs which caused the death 

 of the animal. It may be an infected wound, it may be an infected 

 uterus after calving, or what not. In each and every case there is 

 some germ present which caused the death of the animal. Now
