When a less serious hrood disease is found, it should he determined whether or not Amer- ican foulhrood also is present. AMERICAN FOULBROOD CAUSE American foulhrood is an infectious disease of the brood of bees caused by a bacterium known as Bacillus larvae. It is the most destructive of the brood diseases, is very infectious, and diseased col- onies practically always die. This bacterium causes the death of larvae and pupae by its growth and multiplication within the stomach. It also causes a typical decay of the dead brood. B. lar- vae resists drying, the action of chemicals, both high and low tem- peratures, and the dehydrating action of honey; consequently Amer- ican foulhrood cannot be treated successfully except by burning the infected combs and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original
