Samba virus: a novel mimivirus from a giant rain forest, the Brazilian Amazon

Virology Journal, 2014
BackgroundThe identification of novel giant viruses from the nucleocytoplasmic large DNA viruses group and their virophages has increased in the last decade and has helped to shed light on viral evolution. This study describe the discovery, isolation and

Identification of giant Mimivirus protein functions using RNA interference

Frontiers in Microbiology, 2015
Genomic analysis of giant viruses, such as Mimivirus, has revealed that more than half of the putative genes have no known functions (ORFans). We knocked down Mimivirus genes using short interfering RNA (siRNA) as a proof of concept to determine the ...

Related Giant Viruses in Distant Locations and Different Habitats: Acanthamoeba polyphaga moumouvirus Represents a Third Lineage of the Mimiviridae That Is Close to the Megavirus Lineage

Genome Biology and Evolution, 2012
The 1,021,348 base pair genome sequence of the Acanthamoeba polyphaga moumouvirus, a new member of the Mimiviridae family infecting Acanthamoeba polyphaga, is reported. The moumouvirus represents a third lineage beside mimivirus and megavirus.

Experimental Inoculation in Rats and Mice by the Giant Marseillevirus Leads to Long-Term Detection of Virus

Frontiers in Microbiology, 2018
The presence of the giant virus of amoeba Marseillevirus has been identified at many different sites on the human body, including in the bloodstream of asymptomatic subjects, in the lymph nodes of a child with adenitis, in one adult with Hodgkin's ...

Shan Virus: A New Mimivirus Isolated from the Stool of a Tunisian Patient with Pneumonia

Intervirology, 2013
Objective: Following the isolation of a Marseillevirus from the stool of a healthy young Senegalese and a Mimivirus from a Tunisian patient with pneumonia, we attempted to isolate other giant viruses of amoebae from a large human stool collection ...

Cryopreservation of Paramecium bursaria Chlorella Virus-1 during an active infection cycle of its host [PDF]

, 2019
Best practices in laboratory culture management often include cryopreservation of microbiota, but this can be challenging with some virus particles. By preserving viral isolates researchers can mitigate genetic drift and laboratory-induced selection ...

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.

Microscopic Characterization of the Brazilian Giant Samba Virus

Viruses, 2017
Prior to the discovery of the mimivirus in 2003, viruses were thought to be physically small and genetically simple. Mimivirus, with its ~750-nm particle size and its ~1.2-Mbp genome, shattered these notions and changed what it meant to be a virus. Since
