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.

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.

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

Marine mimivirus relatives are probably large algal viruses
Virology Journal, 2008 Background Acanthamoeba polyphaga mimivirus is the largest known ds-DNA virus and its 1.2 Mb-genome sequence has revealed many unique features. Mimivirus occupies an independent lineage among eukaryotic viruses and its known hosts include only species ...

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 ...

Mimivirus in Pneumonia Patients
Emerging Infectious Diseases, 2005 Mimivirus, the largest virus known to date, is an amebal pathogen like Legionella spp. When mimivirus was used as an antigen in a migration inhibition factor assay, seroconversion was found in patients with both community- and hospital-acquired pneumonia.

Microscopic Characterization of the Brazilian Giant Samba Virus
Viruses, 2017 Prior to the discovery of the mimivirus in 2003, viruses were thought to be physically small and genetically simple. Mimivirus, with its ~750-nm particle size and its ~1.2-Mbp genome, shattered these notions and changed what it meant to be a virus. Since

Pulmonary Infection Related to Mimivirus in Patient with Primary Ciliary Dyskinesia
Emerging Infectious Diseases, 2020 Primary ciliary dyskinesia is a rare autosomal recessive disorder that causes oto-sino-pulmonary disease. We report a case of pulmonary infection related to mimivirus in a 10-year-old boy with primary ciliary dyskinesia that was identified using ...
