A new Zamilon-like virophage partial genome assembled from a bioreactor metagenome
Frontiers in Microbiology, 2015 Virophages replicate within viral factories inside the Acanthamoeba cytoplasm, and decrease the infectivity and replication of their associated giant viruses.

Broad spectrum of mimiviridae virophage allows its isolation using a mimivirus reporter. [PDF]
PLoS ONE, 2013 The giant virus Mimiviridae family includes 3 groups of viruses: group A (includes Acanthamoeba polyphaga Mimivirus), group B (includes Moumouvirus) and group C (includes Megavirus chilensis).

Ecological and evolutionary dynamics of cell-virus-virophage systems. [PDF]
PLoS Computational BiologyMicrobial eukaryotes, giant viruses and virophages form a unique hyperparasitic system. Virophages are parasites of the virus transcription machinery and can interfere with virus replication, resulting in a benefit to the eukaryotic host population ...

Ecogenomics of virophages and their giant virus hosts assessed through time series metagenomics [PDF]
Nature Communications, 2017 Virophages are recently-identified small viruses that infect larger viruses, yet their diversity and ecological roles are poorly understood. Here, Roux and colleagues present time series metagenomics data revealing new virophage genera and their putative

Open questions in the social lives of viruses
Journal of Evolutionary Biology, Volume 36, Issue 11, Page 1551-1567, November 2023., 2023 Social interactions among viruses are diverse and pervasive, with the potential to affect every stage of the viral lifecycle. Here, we explore some of the challenges and opportunities that these interactions present for evolutionary biology. Abstract Social interactions among viruses occur whenever multiple viral genomes infect the same cells, hosts ...

Metabolic reconstruction of the near complete microbiome of the model sponge Ianthella basta
Environmental Microbiology, Volume 25, Issue 3, Page 646-660, March 2023., 2023 Abstract Many marine sponges host highly diverse microbiomes that contribute to various aspects of host health. Although the putative function of individual groups of sponge symbionts has been increasingly described, the extreme diversity has generally precluded in‐depth characterization of entire microbiomes, including identification of syntrophic ...

BioMed Research International, Volume 2023, Issue 1, 2023., 2023 Introduction. Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the

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 ...

Ecology and Evolution, Volume 12, Issue 1, January 2022., 2022 Sporulation in yeast is induced by starvation; resource exploitation by endosymbiont should induce earlier sporulation. We find that the presence of two dsRNA viruses is linked to enhanced sporulation in Saccharomyces cerevisiae. However, further research is required to determine whether high sporulation leads to infection or infection leads to higher ...

Environmental Microbiology, Volume 23, Issue 7, Page 3477-3498, July 2021., 2021 Summary Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the ...
