The National Bee Unit, part of the Central Science Laboratory (an executive agency of the Department for Environment, Food and Rural Affairs, Defra) has been developing novel techniques for detection of bee pathogens. Two different methods are under examination, an antibody-based test for identification of foulbrood diseases for use in the field, and a nucleotide-based laboratory test for virus...
Abstract Two different levels of diversity within a colony were compared for the prevalence pathogens and diseases. Lower genetic was obtained in colonies which queens inseminated with semen collected from drones originating single colony, while greater thirty colonies. Bees tested Varroa destructor infestation, microsporidia Vairimorpha spp. infection, acute bee paralysis virus (ABPV) deformed...
The genome sequences of new viruses often contain many "orphan" or "taxon-specific" proteins apparently lacking homologs. However, because viral proteins evolve very fast, commonly used sequence similarity detection methods such as BLAST may overlook homologs. We analyzed a data set of proteins from RNA viruses characterized as "genus specific" by BLAST. More powerful methods developed recently...
We have cloned and sequenced a 2845 bp cDNA representing the 3'-end of either a new picorna-like virus species or genotype of Solenopsis invicta virus-1 (SINV-1). Analysis of the nucleotide sequence revealed 1 large open reading frame. The amino acid sequence of the translated open reading frame was most identical to structural proteins of SINV-1 (97%), followed by the Kashmir bee virus (KBV, 3...
The importance of honey bees to the world economy far surpasses their contribution in terms of honey production; they are responsible for up to 30% of the world's food production through pollination of crops. Since fall 2006, honey bees in the U.S. have faced a serious population decline, due in part to a phenomenon called Colony Collapse Disorder (CCD), which is a disease syndrome that is like...
Abstract Varroa destructor parasitism is associated with extreme honey bee ( Apis mellifera ) colony losses in the northern hemisphere. causes severe damage, including a decrease longevity and immunosuppression, acts as vector for viruses, such Deformed wing virus (DWV-A). The surveillance of viral pathogens V. samples essential to assess risks emerging virulent variants (such VDV-1) evaluate t...
In colony collapse disorder (CCD), honey bee colonies inexplicably lose their workers. CCD has resulted in a loss of 50 to 90% of colonies in beekeeping operations across the United States. The observation that irradiated combs from affected colonies can be repopulated with naive bees suggests that infection may contribute to CCD. We used an unbiased metagenomic approach to survey microflora in...
