A Diverse Range of Novel RNA Viruses in Geographically Distinct Honey Bee Populations

Journal of Virology, Год журнала: 2017, Номер 91(16)

Опубликована: Май 18, 2017

ABSTRACT Understanding the diversity and consequences of viruses present in honey bees is critical for maintaining pollinator health managing spread disease. The viral landscape ( Apis mellifera ) has changed dramatically since emergence parasitic mite Varroa destructor , which increased virulent variants such as deformed wing virus. Previous genomic studies have focused on colonies suffering from infections by viruses, could mask other species bees, resulting a distorted view diversity. To capture within that are exposed to mites but do not suffer ultimate infestation, we examined populations evolved naturally or been selected resistance . This analysis revealed seven novel isolated sampled globally, including first identification negative-sense RNA bees. Notably, two rhabdoviruses were three geographically diverse locations also parasitizing characterize antiviral response, performed deep sequencing small mites. provided evidence Dicer-mediated immune response while profile was distinct observed Overall, show bee greater than previously thought, encourages additional virome global scale may ultimately improve disease management. IMPORTANCE Honey become increasingly susceptible colony losses due pathogenic date, 24 described with most belonging order Picornavirales Collapsing -infected often overwhelmed high levels picornaviruses. examine underlying employed metatranscriptomics analyses Varroa- resistant Europe, Africa, Pacific. We describe range families, all locations. In sequences indicate these processed Dicer interference pathway, whereas produce strikingly patterns. work increases number known will contribute improved management our important agricultural pollinator.

The evolution of transmission mode

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2017, Номер 372(1719), С. 20160083 - 20160083

Опубликована: Март 13, 2017

This article reviews research on the evolutionary mechanisms leading to different transmission modes. Such modes are often under genetic control of host or pathogen, and in conflict with each other via trade-offs. Transmission may vary among pathogen strains populations. Evolutionary changes mode have been inferred through experimental phylogenetic studies, including associated shifts evolution unusually complex life cycles many parasites. Understanding forces that determine particular presents a fascinating medley problems for which there is lack good data conceptual understanding appropriate methodologies. Our best information comes from studies focused vertical versus horizontal dichotomy. With kinds transitions, theoretical approaches combining epidemiology population genetics providing guidelines determining when how rapidly new evolve, but these still need empirical investigation application cases. Obtaining such knowledge matter urgency relation extant disease threats. part themed issue ‘Opening black box: re-examining ecology parasite transmission’.

Recently identified bee viruses and their impact on bee pollinators

Current Opinion in Insect Science, Год журнала: 2018, Номер 26, С. 120 - 129

Bees are agriculturally and ecologically important plant pollinators. Recent high annual losses of honey bee colonies, reduced populations native wild bees in some geographic locations, may impact the availability affordable food crops diversity abundance species. Multiple factors including viral infections affect pollinator health. The majority well-characterized viruses picorna-like RNA viruses, which be maintained as covert or cause symptomatic death. Next generation sequencing technologies have been utilized to identify additional bee-infecting Lake Sinai Rhabdoviruses. In addition, sequence data is instrumental for defining specific strains characterizing associated pathogenicity, such recent characterization Deformed wing virus master variants (DWV-A, DWV-B, DWV-C) their on

Characterizing the virome of Ixodes ricinus ticks from northern Europe

Scientific Reports, Год журнала: 2017, Номер 7(1)

Abstract RNA viruses are abundant infectious agents and present in all domains of life. Arthropods, including ticks, well known as vectors many concern for human animal health. Despite their obvious importance, the extent structure viral diversity ticks is still poorly understood, particularly Europe. Using a bulk RNA-sequencing approach that captures complete transcriptome, we analysed virome most common tick Europe – Ixodes ricinus . In total, sequencing was performed on six libraries consisting 33 I. nymphs adults sampled Norway. small number animals surveyed, our virus identification pipeline revealed nine diverse novel species, phylogenetically positioned within four different groups bunyaviruses, luteoviruses, mononegavirales partitiviruses sometimes characterized by extensive genetic potentially genus bunyaviruses. This work sheds new light , expands knowledge potential host/vector-associations tick-transmitted several groups, pushes latitudinal limit where it likely to find tick-associated viruses. Notably, phylogenetic analysis presence tick-specific clades span multiple continents, highlighting role important reservoirs.

Abundant and Diverse RNA Viruses in Insects Revealed by RNA-Seq Analysis: Ecological and Evolutionary Implications

Increasing data indicate that insects serve as major reservoirs and vectors of viruses, which account for the continuously increasing ecological burden infectious disease outbreaks. Uncovering hidden diversity viruses in will further understanding evolutionary perspectives emergence insect-associated virus diseases. In this study, we queried transcriptome sequencing (RNA-Seq) from more than 600 species across 32 insect orders dwelling different habitats recovered 1,213 RNA were recapitulated 40 families, 2 unclassified genera, many unspecified viral groups. These novel included well-known within Flaviviridae, Picornavirales, Bunyavirales, Mononegavirales, Nidovirales, Reoviridae, Negevirus More appeared to form clusters previously described taxa or could be resolved paraphyletic, including first astrovirus identified insects, sufficiently divergent warrant establishment new genera families. Additionally, some closely related recognized plant-, fungus-, vertebrate-specific species, implying importance relationships between behavior spread. Comparative genome analyses also revealed high genomic variability with respect flexible gene pool architecture these newly evidence reshuffling discovered Dicistroviridae The reflecting genetically ecologically diverse populations greatly expand our nature highlight biodiversity remains largely unexplored.IMPORTANCE Insects comprise largest proportion animals on earth are frequently implicated transmission vector-borne However, considerable attention has been paid phytophagous hematophagous results provide insufficient biased information about insects.

Twenty-Five New Viruses Associated with the Drosophilidae (Diptera)

Evolutionary Bioinformatics, Год журнала: 2016, Номер 12s2

Опубликована: Янв. 1, 2016

Drosophila melanogaster is an important laboratory model for studies of antiviral immunity in invertebrates, and species provide a valuable system to study virus host range switching. Here, we use metagenomic RNA sequencing about 1600 adult flies discover 25 new viruses associated with six different drosophilid hosts the wild. We also comprehensive listing previously reported from Drosophilidae. The include Iflaviruses, Rhabdoviruses, Nodaviruses, Reoviruses, members unclassified lineages distantly related Negeviruses, Sobemoviruses, Poleroviruses, Flaviviridae, Tombusviridae. Among these are close relatives X Flock House virus, which find association wild immigrans. These two widely used experimental but have not been naturally infect Drosophila. Although detect no DNA viruses, D. immigrans obscura, identify sequences very closely Armadillidium vulgare iridescent (Invertebrate 31), bringing total number found Drosophilidae three.
