CONTAGIOUS DISEASES OP DOMESTICATED ANIMALS. 177 



lobular, and the development of wbicU does not depend on traumatic 

 causes. 



2. From a physiological standpoint in the living animal, epizootic 

 contagious pleuropneumonia is specially characterized by its conta- 

 gious character and by the symptoms of lobular pneumonia. 



3. In an infected place every animal which shows febrile reaction or 

 symptoms of disease of the chest should be considered as suspected of 

 pleuropneumonia. Every animal found in an infected stable or which 

 has been in one within three montlis antecedent, or which has been able 

 to be contaminated in any other way, should be considered as suspected 

 of contamination. 



B. — Prophylaxis. 



1. Recognizing that from the point of view of sanitary police epizo- 

 otic i)leuro-pneumonia is a disease which propagates itself only by con- 

 tagion, and is usually incurable and fatal, the congress declared that to 

 prevent the development and i)ropagation of this malady there should 

 be applied the measures against contagious diseases that are at the 

 same time fatal and incurable. 



2. Animals diseased or suspected of the disease should be sacrificed 

 as quickly as possible. 



3. Contaminated animals or those very much exposed to the conta- 

 gion should be isolated or sacrificed. The slaughter of contaminated 

 animals is especially indicated when the disease manifests itself very 

 exceptionally, or for the first time in a stable belonging to a commune 

 or countrj' ricli in cattle. 



•4. We have to-day experimental proof that it is possible to invest the 

 organism of animals of the horned species with an immunity from con- 

 tagious pleuropneumonia by inoculation with the virus of this malady. 



5. Preventive inoculation, that is to say, that which is iiracticed when 

 the malady does not prevail in a country, ought to be absolutely re- 

 iected. Inoculation, so called, of necessity, that is to say, that which 

 is practiced when the disease exists in a herd, may be permitted but 

 not made obligatory. 



G. The inoculation should always be done by a veterinarian. 



7. It is not proved that an inoculated animal cannot transmit the dis- 

 ease to a sound animal. 



8. Inoculated animals should be reported to the authorities. 



0. (Quarantined animals should be made the object of a special census, 

 and should receiv^e a distinctive brand with a hot iron. 



10. ^'o animal suspected of infection should be moved without pre- 

 vious authorization of the communal administration. The permit to 

 move should only be granted for animals destined to the butchery ; it 

 should only take i)lace in special conditions under the supervision of 

 the police, and in such a manner as to prevent all propagation of the 

 malady.
