main report of the Commiission ^ which has been officially 

 j)ubEshed by the Canadian and L'nited States Governments. 



Based on the information contained in the reports of its com- 

 mittees and on such other information as was brought out in the 

 general discus.sions of the Commission, the following resolutions 

 were adopted for pre.sentation to the American Veterinary Medical 



Association : 



(1) Jjiiseii'iiivjf.vm. 



As a general policy to be observed, all contact between 

 tuberculous and healthy cattle and between healthy cattle and 

 stable-s, cars, etc., which may contain living tubercle bacilli should 

 be prevented. To accomplish this the following specific recom- 

 mendations are made : 



(1) There should be no sale or exchange of animals affected 

 ■vvith tuberculosis e.xcept for immediate slaughter or for breeding 

 piujjoses under official supervision. 



(■2) That the managements of live stock shows .should give 

 preference to cattle known to be free from tuberculosis, either b}' 

 providing special classes for such cattle or in some other practical 

 way, and should also take every precaution to prevent contact 

 between such animals and those not known to be free from disease. 



(.3) Ail live stock shippers should take everj' precaution to 

 see that cars furnished are thoroughly cleansed and disinfected 

 before use. 



(2) Taherculin Te,t. 



(1) That tuberculin, properly used, is an accurate and reliable 

 diagnostic agent for the detection of active tuberculosis. 



(2) That tuberculin may not produce a reaction under the 

 following conditions : 



{a) When the disease is in a period of incubation. (J) When 

 the progress of the disease is arrested, (c) "When the disease is 

 e X t e n s ively general i s e d . 



The last conrlition is relatively rare and may usually be detected 

 by physical examination. 



i?j) On account of the period of incubation and the fact that 

 arrested cases may sooner or later become active, all exposed 

 animals should be retested at intervals of six months to one year. 



(4) That the tubercuHn test should not be applied to any 

 animal having a temperature higher than normal. 



{5) That any animal having given one distinct reaction to 

 tuberculin should thereafter be regarded as tuberculous.
