Stonebrood is caused by Aspergillus flavus and Aspergillus fumigatus and affects both the brood and adult bees.

This practice describes the causes and symptoms of Chalkbrood and Stonebrood, how they spread, how to address and prevent these diseases.

EFB (European Foulbrood)

The European Foulbrood (EFB) is a bacterial disease that affects the honey bee brood. The genetic resistance of some species of bees to this disease may allow, especially in favourable environmental conditions, to overcome the infection without suffering serious damage. However, it should be noted that, even if characterised by a better prognosis than the American Foulbrood, in some areas the EFB has a more malignant manifestation, seriously damaging even very strong bee colonies.

This practice describes the causes and symptoms of EFB, how the disease spreads, and how to address and prevent the disease.
