Seasonal Dynamics of Algae-Infecting Viruses and Their Inferred Interactions with Protists

Viruses, 2019
Viruses are a highly abundant, dynamic, and diverse component of planktonic communities that have key roles in marine ecosystems. We aimed to reveal the diversity and dynamics of marine large dsDNA viruses infecting algae in the Northern Skagerrak, South

Degenerate PCR Primers to Reveal the Diversity of Giant Viruses in Coastal Waters

Viruses, 2018
“Megaviridae” is a proposed family of giant viruses infecting unicellular eukaryotes. These viruses are ubiquitous in the sea and have impact on marine microbial community structure and dynamics through their lytic infection cycle.

The Mimiviridae virophages

, 2013
Les virophages sont des petits virus à ADN possédant une capside icosaédrique de 50-60 nm et un génome de 17 à 26 Kb codant potentiellement pour une vingtaine de gènes.

Ecogenomics of virophages and their giant virus hosts assessed through time series metagenomics [PDF]

, 2017
Virophages are small viruses that co-infect eukaryotic cells alongside giant viruses (Mimiviridae) and hijack their machinery to replicate. While two types of virophages have been isolated, their genomic diversity and ecology remain largely unknown. Here

Marine and giant viruses as indicators of a marine microbial community in a riverine system

MicrobiologyOpen, 2016
Viral communities are important for ecosystem function as they are involved in critical biogeochemical cycles and controlling host abundance. This study investigates riverine viral communities around a small rural town that influences local water inputs.

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 ...

Pan-Genome Analysis of Brazilian Lineage A Amoebal Mimiviruses

Viruses, 2015
Since the recent discovery of Samba virus, the first representative of the family Mimiviridae from Brazil, prospecting for mimiviruses has been conducted in different environmental conditions in Brazil. Recently, we isolated using Acanthamoeba sp.
