EUROPEAN FOULBROOD is a disease of the 

 brood of bees which has caused great losses to 

 American beekeepers. It was first recognized as a 

 distinct disease in the United States by New York 

 beekeepers in 1894, but it has probably been present 

 in the United States for a long ti'me. 



It is important that the beekeeper know whether 

 European or American foulbrood is in his apiary, for 

 the two do not respond to the same treatment. In 

 European foulbrood control the most important step 

 is to prevent the entrance of the disease by keeping 

 all colonies strong and by having all stock resistant 

 to the disease. This can be done successfully even 

 though the disease is in the neighborhood. 



In case, through failure to take all precautions, 

 the disease does enter, there are certain practices by 

 which the disease can be readily eliminated, but all 

 of these must be used with care. 



The facts about the disease on which the pre- 

 ventive and remedial measures are based are dis- 

 cussed in this bulletin.
