A new marseillevirus isolated in Southern Brazil from Limnoperna fortunei [PDF]

Scientific Reports, 2016
Members of the family Marseilleviridae are giant viruses that have the ability to infect amoebas. Such viruses were initially described in 2009. Since then, this family has grown, and diverse members have been found in different environments and ...

A Marseillevirus isolate from the Brazilian wetlands [PDF]

Archives of Virology
Abstract Marseilleviruses are giant viruses that infect amoebas and have been isolated from various environments. Here, we describe a new strain, isolated from a water sample collected from the Paraguay River in the Brazilian Pantanal, which we have named "Marseillevirus pantanense".

Marseillevirus in the Pharynx of a Patient with Neurologic Disorders [PDF]

Emerging Infectious Diseases, 2016
To the Editor: Marseilleviridae is a recently described family of giant amebal viruses (1). Although Marseillevirus, its founding member, and subsequently discovered representatives were isolated primarily from environmental water, marseilleviruses have been recovered from humans (2,3). Senegalvirus, a close Marseillevirus relative, was serendipitously

A long-term prospecting study on giant viruses in terrestrial and marine Brazilian biomes [PDF]

Virology Journal
The discovery of mimivirus in 2003 prompted the search for novel giant viruses worldwide. Despite increasing interest, the diversity and distribution of giant viruses is barely known.

Continuous year-round isolation of giant viruses from brackish shoreline soils. [PDF]

Front Microbiol
Giant viruses, categorized under Nucleocytoviricota, are believed to exist ubiquitously in natural environments. However, comprehensive reports on isolated giant viruses remain scarce, with limited information available on unrecoverable strains, viral ...

A rapid genome‐wide analysis of isolated giant viruses using MinION sequencing

Environmental Microbiology, Volume 25, Issue 11, Page 2621-2635, November 2023., 2023
We evaluated performance of MinION sequencing for giant virus genomics. Re‐sequencing of a prototype marseillevirus by MinION alone provided high‐quality genomes. As a proof of concept, we sequenced genomes of newly isolated giant viruses. Collectively, we concluded that MinION sequencing is an effective approach to rapidly perform a genome‐wide ...

Kinetic Analysis of Acanthamoeba castellanii Infected with Giant Viruses Quantitatively Revealed Process of Morphological and Behavioral Changes in Host Cells

Microbiology Spectrum, 2021
Most virus-infected cells show morphological and behavioral changes, which are called cytopathic effects. Acanthamoeba castellanii, an abundant, free-living protozoan, serves as a laboratory host for some viruses of the phylum Nucleocytoviricota—the ...

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.

First Isolation of a Marseillevirus in the Diptera Syrphidae Eristalis tenax [PDF]

Intervirology, 2013
<b><i>Objective:</i></b> Giant viruses and amoebae are common in freshwater, where they can coexist with various insects. We screened insect larvae to detect giant viruses using a high-throughput method. <b><i>Methods:</i></b> We analyzed 86 <i>Eristalis tenax</i> larvae obtained from stagnant
