Virome of Giant Panda-Infesting Ticks Reveals Novel Bunyaviruses and Other Viruses That Are Genetically Close to Those from Giant Pandas

Microbiology Spectrum, 2022
Tick infestations have been reported as one of the factors threatening the health of giant pandas, but studies of viral pathogens carried by ticks feeding on the blood of giant pandas are limited. To assess whether blood-sucking ticks of giant pandas can

Giant endogenous viral elements in the genome of the model protist Euglena gracilis reveal past interactions with giant viruses [PDF]

Journal of Virology
Genomes of giant viruses (phylum Nucleocytoviricota) have increasingly been found integrated into the genomes of diverse eukaryotes. Here, we report eight giant endogenous viral elements (GEVEs) in the genome of the microalgae Euglena gracilis. The GEVEs

High Transcriptional Activity and Diverse Functional Repertoires of Hundreds of Giant Viruses in a Coastal Marine System

MSystems, 2021
The discovery of giant viruses has transformed our understanding of viral complexity. Although viruses have traditionally been viewed as filterable infectious agents that lack metabolism, giant viruses can reach sizes rivalling cellular lineages and ...

Metabolic arsenal of giant viruses: Host hijack or self-use? [PDF]

eLife, 2022
Viruses generally are defined as lacking the fundamental properties of living organisms in that they do not harbor an energy metabolism system or protein synthesis machinery.

Continuous year-round isolation of giant viruses from brackish shoreline soils [PDF]

Frontiers in Microbiology
Giant viruses, categorized under Nucleocytoviricota, are believed to exist ubiquitously in natural environments. However, comprehensive reports on isolated giant viruses remain scarce, with limited information available on unrecoverable strains, viral ...
