Sputnik virophage disrupts the transcriptional regulation of its host giant virus

Journal of Virology
Sputnik virophages are small double-stranded DNA (dsDNA) viruses that replicate only inside host amoebae infected with giant dsDNA viruses, mimiviruses.

Virus goes viral: an educational kit for virology classes

Virology Journal, 2020
Background Viruses are the most numerous entities on Earth and have also been central to many episodes in the history of humankind. As the study of viruses progresses further and further, there are several limitations in transferring this knowledge to ...

Automated classification of giant virus genomes using a random forest model built on trademark protein families

npj Viruses
Viruses of the phylum Nucleocytoviricota, often referred to as “giant viruses,” are prevalent in various environments around the globe and play significant roles in shaping eukaryotic diversity and activities in global ecosystems.

Haptophyte-infecting viruses change the genome condensing proteins of dinoflagellates

Communications Biology
Giant viruses are extraordinary members of the virosphere due to their structural complexity and high diversity in gene content. Haptophytes are ecologically important primary producers in the ocean, and all known viruses that infect haptophytes are ...

Presence of Protozoan Viruses in Vaginal Samples from Pregnant Women and Their Association with Trichomoniasis

Pathogens
This study was conducted in Armenia and included 32 pregnant women with TV infection and 30 healthy controls. The vaginal virome includes viruses that infect human cells and unicellular eukaryotes such as Trichomonas vaginalis (TV).

A phylogenomic framework for charting the diversity and evolution of giant viruses

PLoS Biology, 2021
Large DNA viruses of the phylum Nucleocytoviricota have recently emerged as important members of ecosystems around the globe that challenge traditional views of viral complexity.

Mimivirus transcription and translation occur at well-defined locations within amoeba host cells

Journal of Virology
Many giant viruses replicate in the cytoplasm in viral factories. How exactly these viral factories are established and where the different steps of the replication cycle occur remain largely obscure.

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality

mBio
This study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.
