A Decade of Improvements in Mimiviridae and Marseilleviridae Isolation from Amoeba

, 2013
International audienceSince the isolation of the first giant virus, the Mimivirus, by T.J. Rowbotham in a cooling tower in Bradford, UK, and after its characterisation by our group in 2003, we have continued to develop novel strategies to isolate ...

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.

The virion of Cafeteria roenbergensis virus (CroV) contains a complex suite of proteins for transcription and DNA repair [PDF]

, 2014
Cafeteria roenbergensis virus (CroV) is a giant virus of the Mimiviridae family that infects the marine phagotrophic flagellate C. roenbergensis. CroV possesses a DNA genome of ~730 kilobase pairs that is predicted to encode 544 proteins. We analyzed the

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

mRNA maturation in giant viruses: variation on a theme [PDF]

, 2015
International audienceGiant viruses from the Mimiviridae family replicate entirely in their host cytoplasm where their genes are transcribed by a viral transcription apparatus. mRNA polyadenylation uniquely occurs at hairpin-forming palindromic sequences

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.
