CONCLUSIONS 



Bad. abortus infection may involve organs of the generative apparatus 

 of bulls, producing chronic inflammatory changes. 



Of the generative organs, the seminal vesicles appear to furnish the 

 most favorable site for the lodgment and propagation of abortion 

 infection. 



The presence of Bad. abortus infection in bulls appears to be more 

 strongly indicated by relatively marked than by slight reactions to the 

 agglutination test for this disease.
