Role of Honey Bee Gut Microbiota in the Control of American Foulbrood and European Foulbrood Diseases

American foulbrood (AFB) and European foulbrood (EFB) are the two most important honey bee brood diseases which impose heavy economic losses to the apiculture industry worldwide by reducing bee population and honey production. Treatment with antibiotics has led to the emergence of antibiotic-resistant strains, calling for alternative safe treatment procedures that could control these diseases. Honey bee gut microbiota is known to affect the overall health of honey bees by enhancing their resistance to a number of diseases via modulation of the immune response and production of different antimicrobial metabolites. The majority of these gut resident bacteria are identified as probiotic bacteria and secure the health of these tiny insects. In the present review, we highlighted the significance of the honey bee gut microbial community and their probiotic potency for the prevention of AFB and EFB diseases in honey bees.
