Evolution of giant pandoravirus revealed by CRISPR/Cas9 [PDF]
Nature Communications, 2023 Giant viruses (GVs) are a hotspot of unresolved controversies since their discovery, including the definition of “Virus” and their origin. While increasing knowledge of genome diversity has accumulated, GV functional genomics was largely neglected. Here,

Continuous year-round isolation of giant viruses from brackish shoreline soils [PDF]
Frontiers in MicrobiologyGiant 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 ...

An Update on Eukaryotic Viruses Revived from Ancient Permafrost [PDF]
Viruses, 2023 One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing organic matter frozen for up to a million years, most of which decomposes ...

Genome Sequences of Two New Pandoravirus Strains Isolated from Brazil and France. [PDF]
Microbiology Resource Announcements, 2022 Pandoraviruses are giant viruses of amoebas with a wide range of genome sizes (1.5 to 2.5 Mbp) and 1-μm ovoid viral particles. Here, we report the isolation, genome sequencing, and annotation of two new strains from the proposed family Pandoraviridae ...

Horizontal transfer of a 180-kbp genomic fraction among the largest viral genomes [PDF]
Applied and Environmental MicrobiologyViruses are generally considered tiny biological entities with small genomes; however, some dsDNA viruses, known as giant viruses, have large genomes that are comparable to those of small bacteria.

Epidemiology and ecology of the sylvatic cycle of African Swine Fever Virus in Kenya [PDF]
Virus ResearchAfrican Swine Fever (ASF) is caused by a DNA virus (AFSV) maintained and transmitted by the Argasid ticks. The re-emergence of the disease in Africa coupled with its rapid spread globally is a threat to the pig industry, food security and livelihoods ...

A Large Open Pangenome and a Small Core Genome for Giant Pandoraviruses
Frontiers in Microbiology, 2018 Giant viruses of amoebae are distinct from classical viruses by the giant size of their virions and genomes. Pandoraviruses are the record holders in size of genomes and number of predicted genes. Three strains, P. salinus, P. dulcis, and P.
