The Bulletin 11 



for any other purpose and new quarters can be found for the hogs, it 

 would be much safer. 



Susceptible hogs should be treated with anti-hog cholera serum if they 

 are to be placed on the infected grounds under twelve months. Since it 

 is practically impossible to thoroughly disinfect a large premise, the hogs 

 should be immuned to cholera before they are allowed access to the in- 

 fected grounds, but bear in mind it is always well to use disinfectants 

 liberally around hog houses. 



When cholera has broken out in a herd of hogs in a field, this field 

 should be covered with a heavy application of lime, and a crop grown on 

 it for one year before it i's used again, unless the hogs are "immune." 



SOME OF THE WAYS BY AVIIK II HOG CHOLERA IS SPREAD 



It is well to bear in mind that every case of hog cholera comes from a 

 previous case of cholera. It is impossible to produce a case of cholera 

 without having the germs that cause hog cholera. No matter how filthy 

 the lots or pens in which the hogs are kept, they cannot have cholera 

 unless the germs from a previous case of cholera are introduced. The 

 disease cannot arise spontaneously. All secretions and excretions are 

 laden with the infection and if allowed to enter into a susceptible hog's 

 system will produce cholera. 



Since hog cholera must come from some previous case of cholera, it 

 behooves us to see that the carcasses of all hogs dying from cholera are 

 properly disposed of. The infected lots and pens should be held under 

 strict quarantine. All cholera carcasses should be burned or buried deep 

 and covered with lime. Cholera may be carried from an infected premise 

 by dogs, cats, rabbits, crows, pigeons, buzzards, or any other animal that 

 moves from one place to another. 



The Tnrkej Buzzard 



The turkey buzzard is one of the three worst agents by which hog 

 cholera is disseminated in this State. The other two are free range, and 

 running streams and overflows. "Whenever the carcass of an animal is 

 left on top of the ground, no matter what was the cause of death, the 

 buzzards are certain to be attracted to the carcass. If the carcass is one 

 of a cholera hog they feed upon it and fly away to some other farm, at 

 time^ many miles away, and they are certain to carry the hog cholera 

 germs with them. If these germs are deposited in reach of other hogs 

 they are certain to cause an outbreak of cholera. The importance of 

 burying all carcasses, especially all cholera carcasses and carcasses of 

 other infectious diseases, cannot be emphasized too much. 



For many years the turkey buzzard, or vulture, was protected by law 

 in a great many states, as they were considered scavengers, but since it 

 has been demonstrated that they are one of the worst agents we have in 

 disseminating disease germs, especially the germ of hog cholera, and
