molecular and phylogenetic characterization of honey bee viruses, nosema microsporidia, protozoan parasites, and parasitic mites in china.china has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in chinese apiaries. we thus conducted a molecular survey of honey bee rna viruses, nosema microsporidia, protozoan parasites, and tracheal mites associated with nonnative apis mellifera ligustica and native apis cerana cerana colonies in china. we found the presence of ...201323467539
negative correlation between nosema ceranae spore loads and deformed wing virus infection levels in adult honey bee workers.interactions between pathogens might contribute to honey bee colony losses. here we investigated if there is an association between the microsporidian nosema ceranae and the deformed wing virus (dwv) in different body sections of individual honey bee workers (apis mellifera ligustica) under exclusion of the vector varroa destructor. our data provide correlational evidence for antagonistic interactions between the two pathogens in the midgut of the bees.201121939664
