Mimiviridae, Marseilleviridae, and virophages as emerging human pathogens causing healthcare-associated infections

GMS Hygiene and Infection Control, 2014
[english] Aim: During the last decade it became obvious that viruses belonging to and families (order Megavirales), may be potential causative agents of pneumonia. Thus, we have performed a review of the association of , , and virophages with pneumonia,

Exploration of the propagation of transpovirons within Mimiviridae reveals a unique example of commensalism in the viral world [PDF]

ISME Journal, 2019
Acanthamoeba-infecting Mimiviridae are giant viruses with dsDNA genome up to 1.5 Mb. They build viral factories in the host cytoplasm in which the nuclear-like virus-encoded functions take place.

Related Giant Viruses in Distant Locations and Different Habitats: Acanthamoeba polyphaga moumouvirus Represents a Third Lineage of the Mimiviridae That Is Close to the Megavirus Lineage [PDF]

Genome Biology and Evolution, 2012
The 1,021,348 base pair genome sequence of the Acanthamoeba polyphaga moumouvirus, a new member of the Mimiviridae family infecting Acanthamoeba polyphaga, is reported. The moumouvirus represents a third lineage beside mimivirus and megavirus.

Comparative Genomics of Chrysochromulina Ericina Virus and Other Microalga-Infecting Large DNA Viruses Highlights Their Intricate Evolutionary Relationship with the Established Mimiviridae Family [PDF]

Journal of Virology, 2017
ABSTRACTChrysochromulina ericina virus CeV-01B (CeV) was isolated from Norwegian coastal waters in 1998. Its icosahedral particle is 160 nm in diameter and encloses a 474-kb double-stranded DNA (dsDNA) genome. This virus, although infecting a microalga (the haptophyceaeHaptolina ericina, formerlyChrysochromulina ericina), is phylogenetically related to

Megavirus baoshanense Mb0671 modulates host translation and increases viral fitness [PDF]

Frontiers in Microbiology
Amoeba giant viruses encode many translation-related proteins, but the function of these proteins remains obscure. In the current work, we studied the potential eukaryotic translation initiation factor 4A (eIF4A, Mb0671) encoded by Megavirus baoshanense,

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.

Mimiviridae: clusters of orthologous genes, reconstruction of gene repertoire evolution and proposed expansion of the giant virus family [PDF]

Virology Journal, 2013
Abstract Background The family Mimiviridae belongs to the large monophyletic group of Nucleo-Cytoplasmic Large DNA Viruses (NCLDV; proposed order Megavirales) and encompasses giant viruses infecting amoeba and probably other unicellular eukaryotes.

Year-round dynamics of amplicon sequence variant communities differ among eukaryotes, Mimiviridae, and prokaryotes in a coastal ecosystem [PDF]

bioRxiv, 2021
Coastal seawater is the habitat of different microbial communities. These communities are affected by seasonal environmental changes and fluctuating nutrient availability, as well as competitive and cooperative interspecific interactions.

Commensalism in the Mimiviridae giant virus family [PDF]

bioRxiv, 2019
Acanthamoeba-infecting Mimiviridae belong to three clades: Mimiviruses (A), Moumouviruses (B) and Megaviruses (C). The uniquely complex mobilome of these giant viruses includes virophages and linear 7 kb-DNA molecules called “transpovirons”.

Isolation and Identification of a Large Green Alga Virus (Chlorella Virus XW01) of Mimiviridae and Its Virophage (Chlorella Virus Virophage SW01) by Using Unicellular Green Algal Cultures

Journal of virology, 2022
Parasitic virophages are small unicellular eukaryotic dsDNA viruses that rely on the viral factories of coinfecting giant/large dsDNA viruses for propagation.
