Fifteenth Annual Report on 



Eradication of PuUorum Disease 



in Massachusetts 



By the Poultry Disease Control Laboratory 



The purpose of this bulletin is to report the results of puUorum-disease testing 

 for the 1934-35 season. In the discussion of the results it is pointed out that 

 progress is being made in the eradication of the disease as revealed by increases 

 in the number of tested birds and tested samples of which only 0.39 percent were 

 positive. The average percentage of positive tests is the lowest attained during 

 the fifteen-year testing period. Salient factors which play a part in successful 

 eradication are emphasized.
