Re: Varroa mites

Not sure why the thread name is Varroa mites, because the link that I opened told about a Finnish scientist team developing a vaccination against AFB.
here is their web site: https://primebee.org/

"Bees may soon get an ally in their fight against bacterial disease — one of the most serious threats the pollinators face — in the form of an edible vaccine. That's the promise held out by researchers in Finland, who say they've made the first-ever vaccine for insects, aimed at helping struggling honeybee populations.

The scientists are targeting one of bees' most deadly enemies: American foulbrood, or AFB, an infectious disease that devastates hives and can spread at a calamitous rate. Often introduced by nurse bees, the disease works by bacteria feeding on larvae — and then generating more spores, to spread further.

The idea of a potential new weapon to fight AFB has generated excitement in the beekeeping community, along with some skepticism about the claim of a vaccine — which remains in the testing phase. The news comes three years after the same researchers were hailed in Entomology Today as discovering the "key to bee vaccination."

Scientists Dalial Freitak and Heli Salmela of the University of Helsinki say their new vaccine solves a vexing problem researchers have faced as they try to save bees from disease. Because insects' immune systems don't have antibodies, they essentially lack a "memory" for fighting diseases.

Freitak says she and her colleagues were able to get around that limitation, after she realized Salmela's study of a protein called vitellogenin seemed to complement her own work, in which she found insects that were exposed to bacteria were able to impart an elevated immune response to their offspring.

From the university's news release:

"When the queen bee eats something with pathogens in it, the pathogen signature molecules are bound by vitellogenin. Vitellogenin then carries these signature molecules into the queen's eggs, where they work as inducers for future immune responses."

"Now we've discovered the mechanism to show that you can actually vaccinate them," Freitak said in a news release. "You can transfer a signal from one generation to another." "

I changed the thread title to better reflect the content of the linked article.


Please keep in mind that messages with 'links only' are generally not suitable for posting by themselves at Beesource. Messages with links should always include at least a few words of explanation as to what to expect at the link.
