bumblebee New vaccine could save bees from colony collapse disorder

New vaccine could save bees from colony collapse disorder
excerpt from above:

The drug, Remembee, which was developed by Beeologics, has completed successful clinical trials on millions of bees in North America. Not only has it proved effective in maintaining bee health, but it also improved the longevity of bees and increased the honey in the hives.

Based on Nobel prize-winning RNAI technology, Remembee helps the bees overcome IAVP virus, also discovered in Israel, which has been associated with colony collapse in scientific literature.

The first alarms about the sudden widespread disappearance of honeybees came in late 2006, and the phenomenon soon had a name: colony collapse disorder. In the two years that followed, about one-third of bee colonies vanished, while researchers toiled to figure out what was causing the collapse. A study published last week in the Proceedings of the National Academy of Sciences surmises that there may not be a single pathogen involved but a collection of culprits. What have entomologists and beekeepers learned in the last few years of dealing with the crisis? We asked May R. Berenbaum, an author of the study, and other experts for an update.

Abstract

Colony collapse disorder (CCD) is a mysterious disappearance of honey bees that has beset beekeepers in the United States since late 2006. Pathogens and other environmental stresses, including pesticides, have been linked to CCD, but a causal relationship has not yet been demonstrated. Because the gut acts as a primary interface between the honey bee and its environment as a site of entry for pathogens and toxins, we used whole-genome microarrays to compare gene expression between guts of bees from CCD colonies originating on both the east and west coasts of the United States and guts of bees from healthy colonies sampled before the emergence of CCD. Considerable variation in gene expression was associated with the geographical origin of bees, but a consensus list of 65 transcripts was identified as potential markers for CCD status. Overall, elevated expression of pesticide response genes was not observed. Genes involved in immune response showed no clear trend in expression pattern despite the increased prevalence of viruses and other pathogens in CCD colonies. Microarray analysis revealed unusual ribosomal RNA fragments that were conspicuously more abundant in the guts of CCD bees. The presence of these fragments may be a possible consequence of picorna-like viral infection, including deformed wing virus and Israeli acute paralysis virus, and may be related to arrested translation. Ribosomal fragment abundance and presence of multiple viruses may prove to be useful diagnostic markers for colonies afflicted with CCD.
