Post-Mortem Detection and Visualization of Mimivirus Reactivation in Fatal Viral Pneumonia [PDF]

Viruses
Mimivirus, a giant double-stranded DNA virus ($1.2$ Mbp), possesses unique bacteria-like features, including a Gram-positive staining reaction due to peptidoglycan-containing surface fibers.

The Discovery of a New Mimivirus Isolate in Association with Virophage-Transpoviron Elements in Brazil Highlights the Main Genomic and Evolutionary Features of This Tripartite System

Viruses, 2022
Mimiviruses are giant viruses of amoeba that can be found in association with virophages. These satellite-like viruses are dependent on the mimivirus viral factory to replicate.

Elucidating the protein interaction network of one of the largest icosahedral capsids in the virosphere [PDF]

The EMBO Journal
Giant viruses challenge traditional boundaries of virology with their large particle sizes, complex genomes, and unique replication strategies. Yet, despite its 750 nm diameter and incorporation of dozens of proteins, the mimivirus virion retains an ...

Acanthamoeba polyphaga de novo transcriptome and its dynamics during Mimivirus infection [PDF]

Scientific Reports
Mimivirus bradfordmassiliense (Mimivirus) is a giant virus that infects Acanthamoeba species – opportunistic human pathogens. Long- and short-read sequencing were used to generate a de novo transcriptome of the host and followed the dynamics of both host

Broad Spectrum of Mimiviridae Virophage Allows Its Isolation Using a Mimivirus Reporter [PDF]

PLoS ONE, 2013
The giant virus Mimiviridae family includes 3 groups of viruses: group A (includes Acanthamoeba polyphaga Mimivirus), group B (includes Moumouvirus) and group C (includes Megavirus chilensis).

Intracellular iron positively modulates the replicative cycle of mimiviruses, increasing virus production [PDF]

Journal of Virology
Mimiviruses, members of the Nucleocytoviricota phylum, produce large, pseudo-icosahedral virions densely coated with fibrils, except at a specialized fivefold vertex known as the stargate.

Identification of giant Mimivirus protein functions using RNA interference

Frontiers in Microbiology, 2015
Genomic analysis of giant viruses, such as Mimivirus, has revealed that more than half of the putative genes have no known functions (ORFans). We knocked down Mimivirus genes using short interfering RNA (siRNA) as a proof of concept to determine the ...
