Prevalence and Seasonal Variations of Six Bee Viruses in Apis mellifera L. and Varroa destructor Mite Populations in France
Data indicate that bee virus infections occur persistently in bee populations despite the lack of clinical signs, suggesting that colony disease outbreaks might result from environmental factors that lead to activation of viral replication in bees. Expand
Structure and assembly of large lipid-containing dsDNA viruses
Cryo-EM studies of CIV and PBCV-1 show that both viruses have profiles characteristic of icosahedra viewed in different orientations, suggesting a common evolutionary origin and therefore serve as a paradigm for other large viruses, such as African swine fever virus, frog virus-3 and many others. Expand
Infectious hypodermal and hematopoietic necrosis virus of shrimp is related to mosquito brevidensoviruses.
IHHNV is closely related to densoviruses of the genus Brevidensovirus in the family Parvoviridae, and it is proposed to rename this virus Penaeus stylirostris densovirus (PstDNV). Expand
Polymerase Chain Reaction detection of deformed wing virus (DWV) in Apis mellifera and Varroa destructor
A search for DWV in 40 colonies showed that DWV is broadly distributed in bee colonies and mites, and greater virus prevalence of virus was detected in Bees collected in autumn compared to bees collected in spring or during the summer period. Expand
Analysis of Virion Structural Components Reveals Vestiges of the Ancestral Ichnovirus Genome
Many thousands of endoparasitic wasp species are known to inject polydnavirus (PDV) particles into their caterpillar host during oviposition, causing immune and developmental dysfunctions thatExpand
Viral load estimation in asymptomatic honey bee colonies using the quantitative RT-PCR technique
A molecular method to estimate the viral loads for six different RNA viruses in bee and mite individuals collected from seemingly healthy colonies showed very large viral titres in some samples. Expand
Densonucleosis viruses constitute an increasingly diversified subfamily among the parvoviruses
A taxonomic structure for the Densovirinae subfamily including four genera instead of the three adopted recently by the ICTV is proposed, and one putative genus, Bidensovirus, is proposed for densoviruses with a bipartite genome which replicate differently from other parvoviruses. Expand
Reassessment of the taxonomic position of Rickettsiella grylli.
The 16S rRNA gene sequence of Rickettsiella grylli, an intracellular parasite of Gryllus bimaculatus and related species of crickets, is determined and indicates that R. gryelli should be removed from the order Rickettsiales. Expand
Molecular biology of Densovirinae.
Complete nucleotide sequence of the cloned infectious genome of Junonia coenia densovirus reveals an organization unique among parvoviruses.
The complete viral sequence of pBRJ, a recombinant plasmid encompassing an infectious Junonia coenia densovirus (JcDNV) genome, is reported here to suggest a common mechanism of DNA replication for these parvoviruses. Expand
