AMERICAN FOULBROOD is a disease of the 

 - brood of bees which causes serious losses to bee- 

 keepers. Its occurrence is practically world-wide, it 

 attacks all races of bees, and strong colonies are as 

 liable to infection as weak ones. 



It is important that the beekeeper recognize the 

 symptoms of the disease and be familiar with the 

 manner in which it is spread, in order that he may 

 take precautions to keep it out of his apiary and to 

 prevent it from spreading from one colony to 

 another in case any of his colonies become infected. 

 He should also know how to treat the disease in the 

 most effective way. Such information is given in 

 this bulletin. It is impossible to manipulate colo- 

 nies so that they cannot contract the disease, but 

 much worry and financial loss can be avoided by 

 dealing promptly and effectively with the disease as 

 soon as it appears. 



Samples of brood suspected of being diseased 

 are diagnosed free of charge by the Division of 

 Bee Culture, Bureau of Entomology, United States 

 Department of Agriculture, Washington, D.C. 



This bulletin supersedes Farmers' Bulletin 1084, entitled
