Bacteriophages pass through candle‐shaped porous ceramic filters: Application for the collection of viruses in soil water

MicrobiologyOpen, Volume 11, Issue 5, October 2022., 2022
This study proposes to use porous candles as a new tool for collecting soil water viruses. In the first step, the passage of model viruses through the ceramic part of the candles was investigated. Regarding the field application, the experiments carried out showed a successful recovery of viruses, demonstrating the relevance and efficiency of such a ...

Megaviruses contain various genes encoding for eukaryotic vesicle trafficking factors

Traffic, Volume 23, Issue 8, Page 414-425, August 2022., 2022
Giant viruses enter their eukaryotic host cells by phagocytosis. For reproduction, they hijack the host cell's membranes by an unknown mechanism. Here, we found that giant viruses express several core factors of the eukaryotic vesicle fusion machinery, including SNARE, Rab, SM proteins, and the disassembly protein NSF.

Adaptive evolution of viruses infecting marine microalgae (haptophytes), from acute infections to stable coexistence

Biological Reviews, Volume 97, Issue 1, Page 179-194, February 2022., 2022
ABSTRACT Collectively known as phytoplankton, photosynthetic microbes form the base of the marine food web, and account for up to half of the primary production on Earth. Haptophytes are key components of this phytoplankton community, playing important roles both as primary producers and as mixotrophs that graze on bacteria and protists.

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]

, 2013
Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

The Three-Dimensional Structure of Mimivirus [PDF]

Intervirology, 2010
Mimivirus, the prototypic member of the new family of <i>Mimiviridae</i>, is the largest virus known to date. Progress has been made recently in determining the three-dimensional structure of the 0.75-µm diameter virion using cryo-electron microscopy and atomic force microscopy.

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

Zooming on dynamics of marine microbial communities in the phycosphere of Akashiwo sanguinea (Dinophyta) blooms

Molecular Ecology, Volume 30, Issue 1, Page 207-221, January 2021., 2021
Abstract Characterizing ecological relationships between viruses, bacteria and phytoplankton in the ocean is critical to understanding the ecosystem; however, these relationships are infrequently investigated together. To understand the dynamics of microbial communities and environmental factors in harmful algal blooms (HABs), we examined the ...

Giant viruses, giant chimeras: The multiple evolutionary histories of Mimivirus genes

BMC Evolutionary Biology, 2008
Background Although capable to evolve, viruses are generally considered non-living entities because they are acellular and devoid of metabolism. However, the recent publication of the genome sequence of the Mimivirus, a giant virus that parasitises ...
