| The European Commission identifies disease and viruses such as Varroa destructor, American foulbrood, European foulbrood, Nosema spp. |
| Probably foulbrood, but none of the four books I had contained a section on diseases. |
| American and European foulbrood diseases were not found in all the colonies subjected to the pathology tests. |
| Insecticides killing bees was a concern, but American foulbrood disease was the biggest problem. |
| The long familiar diseases and pests include American foulbrood, the far less serious European foulbrood, the protozoan Nosema apis, the wax moth, and the black bear. |
| The usual causes of honeybee deaths include varroa mites, hive beetles, and American foulbrood. |
