Antiviral activity of bee bread derived from polish apiaries.

Bee bread is a product of fermentation of bee-collected pollen and revealed a high nutritional value. Other bee products, such as honey and propolis, are known for their antiviral activity, but bee bread is still under investigation, thus its antiviral potential is still unspecified. For investigation antiviral activity of bee bread samples, cytotoxicity assay, antiviral assay against Influenza A virus and Real-Time PCR was performed. For examination of the correlation between bee bread components and antiviral potential of these products, total phenolic, flavonoid and protein content and glucose oxidase activity of tested extratcs was measured.
