Bee Bread, Bee Pollen Show Antimicrobial Activity

Bee-collected pollen (BCP) is a well-known functional food. Honey bees process the collected pollen and store it in the hive, inside the comb cells. The processed pollen is called bee- bread or ambrosia and it is the main source of proteins, lipids, vitamins, macro-and micro-elements in honey bee nutrition. During storage, beebread undergoes solid state fermentation which preserves it and increases the bioavailability of nutrients. Research on beebread has been rather limited until now. In recent years, there is an increasing interest regarding the antimicrobial properties of BCP and beebread, due to emerging antimicrobial resistance by pathogens. Both BCP and beebread exhibit antimicrobial properties against diverse pathogens, like bacteria and fungi. As is the case with other bee products, lack of antimicrobial resistance might be attributed to the synergy of more than one antimicrobial compounds within BCP and beebread. Furthermore, BCP and bee bread exert targeted activity against pathogens and affect the host microbiome in a prebiotic manner. This review aims to present up to date research findings regarding these aspects as well as to discuss current challenges and future perspectives in the field.

...BCP or BB demonstrate selective antimicrobial activity that is usually higher against Gram-positive compared to Gram-negative bacteria. Strain specificity should be further investigated to identify BCP/BB compounds responsible for that. In that respect more studies should be conducted towards exploring synergy of BCP and BB extracts (or compounds detected within) and antibiotics. This synergy could prevent or delay microbial resistance which is a major public health issue.
