The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea

eLife, 2018
Giant viruses are ecologically important players in aquatic ecosystems that have challenged concepts of what constitutes a virus. Herein, we present the giant Bodo saltans virus (BsV), the first characterized representative of the most abundant group of ...

The effects of stress on gut virome: Implications on infectious disease and systemic disorders

MicrobiologyOpen, Volume 13, Issue 5, October 2024.
Stress conditions can weaken the host's immune system, affecting the entire gut–brain axis. Concurrently, disruptions in the composition of the gut microbiota are associated with exacerbations of diseases. This review explores the complex interplay between stress, gut virome, and the host immune system.

A panoramic view of the virosphere in three wastewater treatment plants by integrating viral‐like particle‐concentrated and traditional non‐concentrated metagenomic approaches

iMeta, Volume 3, Issue 3, June 2024.
Our comparative analysis unveiled the distinct advantages of two methods in capturing the complexity of viral communities and their functions in wastewater treatment plants. The non‐concentrated (NC) metagenomic approach identified a higher number of viral contigs, though it had a lower yield of high‐quality contigs.

Role of the R349 Gene and Its Repeats in the MIMIVIRE Defense System

Frontiers in Microbiology, 2019
MIMIVIRE is a defense system described in lineage A Mimivirus (Mimiviridae family) that mediates resistance against Zamilon virophage. It is composed of putative helicase and nuclease associated with a gene of unknown function called R349, which contains

Dinucleotide biases in the genomes of prokaryotic and eukaryotic dsDNA viruses and their hosts

Molecular Ecology, Volume 33, Issue 6, March 2024.
Abstract The genomes of cellular organisms display CpG and TpA dinucleotide composition biases. Such biases have been poorly investigated in dsDNA viruses. Here, we show that in dsDNA virus, bacterial, and eukaryotic genomes, the representation of TpA and CpG dinucleotides is strongly dependent on genomic G + C content.

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.

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.
