Amoebal Tubulin Cleavage Late during Infection Is a Characteristic Feature of Mimivirus but Not of Marseillevirus. [PDF]

Microbiology Spectrum, 2022
Mimivirus and Marseillevirus infections of Acanthamoeba castellanii, like most other viral infections, induce cytopathic effects (CPE). The details of how they bring about CPE and to what extent and how they modify the host cytoskeletal network are ...

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 ...

A Brazilian Marseillevirus Is the Founding Member of a Lineage in Family Marseilleviridae

Viruses, 2016
In 2003, Acanthamoeba polyphaga mimivirus (APMV) was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae.

Kinetic Analysis of Acanthamoeba castellanii Infected with Giant Viruses Quantitatively Revealed Process of Morphological and Behavioral Changes in Host Cells

Microbiology Spectrum, 2021
Most virus-infected cells show morphological and behavioral changes, which are called cytopathic effects. Acanthamoeba castellanii, an abundant, free-living protozoan, serves as a laboratory host for some viruses of the phylum Nucleocytoviricota—the ...

Analysis of a Marseillevirus Transcriptome Reveals Temporal Gene Expression Profile and Host Transcriptional Shift

Frontiers in Microbiology, 2020
Marseilleviruses comprise a family of large double-stranded DNA viruses belonging to the proposed order “Megavirales.” These viruses have a circular genome of ∼370 kbp, coding hundreds of genes.

Comparative Analysis of the Circular and Highly Asymmetrical Marseilleviridae Genomes

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)
