"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 time. 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 sued with care. The facts about the disease on which the preventive and remedial measures are based are discussed in this bulletin."--P. .
