Vaccinated Bees

Dalan AFB Vaccinated Queens, Package Bees and Bee Nucs.

There are many factors that stress honeybee colonies. These may include parasites, predators, poisoning by herbicides and pesticides, loss of food due to fire and drought, and bacterial, fungal, or viral diseases. Among these, American Foulbrood (AFB) is among the most devastating of bee bacterial infections. The bacterial spores that cause AFB have been found to be present in up to 50% of hives tested in Canada and the United States.  A bee vaccine was developed by Dalan Animal Health, this breakthrough in honeybee care is the first and only biologic conditionally licensed by the USDA-CVB to help in the fight against AFB. The nee vaccine is safe, non-chemical, and suitable for use in organic agriculture. When queen bees are orally inoculated with Dalan’s vaccine, protection works through a biological mechanism called transgenerational immune priming (TGIP), whereby the queen passes immunity to her daughters before they hatch. The honeybee vaccine exposes queen bees to inactive bacteria, which enables the larvae hatched in the hive to resist infection.
