Good news! Human ingenuity to the rescue of these important pollinators!
From the abstract:
"Pollination services to increase crop production are becoming more and more important ... High-density, commercial beekeeping has become a key link in the food supply chain, and diseases have become a central issue in hive losses around the world. American Foulbrood (AFB) disease is a highly contagious bacterial brood disease in honey bees (Apis mellifera), leading to hive losses worldwide. The causative agent is the Gram+ bacterium Paenibacillus larvae, which is able to infect honey bee larvae during the first 3 days of their lives. It can be found in hives around the world with viable spores for decades. Antibiotics are largely ineffective in treating the disease as they are only efficient against the vegetative state. Once a hive shows the clinical manifestation of the disease, the only effective way to eradicate it and prevent the spread of the disease is by burning the hive, the equipment, and the colony. Because of its virulent nature and detrimental effects on honey bee colonies, AFB is classified as a notifiable disease worldwide. Effective, safe, and sustainable methods are needed to ensure the wellbeing of honey bee colonies. Even though insects lack antibodies, which are the main requisites for trans-generational immune priming (TGIP), they can prime their offspring against persisting pathogens. Here, we demonstrate an increased survival of infected honey bee larvae after their queen was vaccinated, compared to offspring of control queens (placebo vaccinated). These results indicate that TGIP in insects can be used to majorly enhance colony health, protect commercial pollinators from deadly diseases, and reduce high financial and material losses to beekeepers."
