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.

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

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.

Mimivirus transcription and translation occur at well-defined locations within amoeba host cells [PDF]

Journal of Virology
Many giant viruses replicate in the cytoplasm in viral factories. How exactly these viral factories are established and where the different steps of the replication cycle occur remain largely obscure.

Amoebal Tubulin Cleavage Late during Infection Is a Characteristic Feature of Mimivirus but Not of Marseillevirus

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 ...

Detection of Mimivirus from respiratory samples in tuberculosis-suspected patients

Scientific Reports, 2022
Acanthamoeba polyphaga mimivirus (APMV), a species of amoeba-infecting giant viruses, has recently emerged as human respiratory pathogens. This study aimed to evaluate the presence of Mimivirus in respiratory samples, collected from tuberculosis (TB ...

Hybrid Sequencing Resolved Inverted Terminal Repeats in the Genome of Megavirus Baoshan

Frontiers in Microbiology, 2022
Mimivirus is a group of amoeba-infecting DNA viruses with linear double-strand genome. It is found to be ubiquitous in nature worldwide. Here, we reported the complete genome of a new member of Mimivirus lineage C isolated from a fresh water pond in ...

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.

Modulation of the expression of mimivirus-encoded translation-related genes in response to nutrient availability during Acanthamoeba castellanii infection

Frontiers in Microbiology, 2015
The complexity of giant virus genomes is intriguing, especially the presence of genes encoding components of the protein translation machinery such as transfer RNAs and aminoacyl-tRNA-synthetases; these features are uncommon among other viruses. Although
