Fifteen Marseilleviruses Newly Isolated From Three Water Samples in Japan Reveal Local Diversity of Marseilleviridae [PDF]

Frontiers in Microbiology, 2019
The family Marseilleviridae, defined as a group of icosahedral double-stranded DNA viruses with particle size of approximately 250 nm and genome size of 350–380 kbp, belongs to the nucleo-cytoplasmic family of large DNA viruses.

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 ...

A novel capsid protein network allows the characteristic internal membrane structure of Marseilleviridae giant viruses [PDF]

Scientific Reports, 2022
Marseilleviridae is a family of giant viruses, showing a characteristic internal membrane with extrusions underneath the icosahedral vertices. However, such large objects, with a maximum diameter of 250 nm are technically difficult to examine at sub ...

Marseilleviruses: An Update in 2021 [PDF]

Frontiers in Microbiology, 2021
The family Marseilleviridae was the second family of giant viruses that was described in 2013, after the family Mimiviridae. Marseillevirus marseillevirus, isolated in 2007 by coculture on Acanthamoeba polyphaga, is the prototype member of this family ...

Comparative Analysis of the Circular and Highly Asymmetrical Marseilleviridae Genomes [PDF]

Viruses, 2020
Marseilleviridae members are large dsDNA viruses with icosahedral particles 250 nm in diameter infecting Acanthamoeba. Their 340 to 390 kb genomes encode 450 to 550 protein-coding genes. Since the discovery of marseillevirus (the prototype of the family)

Nucleosome Structures Built from Highly Divergent Histones: Parasites and Giant DNA Viruses [PDF]

Epigenomes, 2022
In eukaryotes, genomic DNA is bound with histone proteins and packaged into chromatin. The nucleosome, a fundamental unit of chromatin, regulates the accessibility of DNA to enzymes involved in gene regulation.

Presence of Protozoan Viruses in Vaginal Samples from Pregnant Women and Their Association with Trichomoniasis [PDF]

Pathogens
This study was conducted in Armenia and included 32 pregnant women with TV infection and 30 healthy controls. The vaginal virome includes viruses that infect human cells and unicellular eukaryotes such as Trichomonas vaginalis (TV).

Melbournevirus encodes a shorter H2B-H2A doublet histone variant that forms structurally distinct nucleosome structures [PDF]

Nature Communications
Unique among viruses, some giant viruses utilize histones to organize their genomes into nucleosomes. Melbournevirus encodes a distinct H2B-H2A histone doublet variant in addition to the canonical H4-H3 and H2B-H2A doublets.
