pathogen prevalence and abundance in honey bee colonies involved in almond pollination.honey bees are important pollinators of agricultural crops. since 2006, us beekeepers have experienced high annual honey bee colony losses, which may be attributed to multiple abiotic and biotic factors, including pathogens. however, the relative importance of these factors has not been fully elucidated. to identify the most prevalent pathogens and investigate the relationship between colony strength and health, we assessed pathogen occurrence, prevalence, and abundance in western us honey bee c ...201727053820
temporal analysis of the honey bee microbiome reveals four novel viruses and seasonal prevalence of known viruses, nosema, and crithidia.honey bees (apis mellifera) play a critical role in global food production as pollinators of numerous crops. recently, honey bee populations in the united states, canada, and europe have suffered an unexplained increase in annual losses due to a phenomenon known as colony collapse disorder (ccd). epidemiological analysis of ccd is confounded by a relative dearth of bee pathogen field studies. to identify what constitutes an abnormal pathophysiological condition in a honey bee colony, it is criti ...201121687739
a unique nodavirus with novel features: mosinovirus expresses two subgenomic rnas, a capsid gene of unknown origin, and a suppressor of the antiviral rna interference pathway.insects are a reservoir for many known and novel viruses. we discovered an unknown virus, tentatively named mosinovirus (monv), in mosquitoes from a tropical rainforest region in côte d'ivoire. the monv genome consists of two segments of positive-sense rna of 2,972 nucleotides (nt) (rna 1) and 1,801 nt (rna 2). its putative rna-dependent rna polymerase shares 43% amino acid identity with its closest relative, that of the pariacoto virus (family nodaviridae). unexpectedly, for the putative capsid ...201425210176
