Marseillevirus-Like Virus Recovered From Blood Donated by Asymptomatic Humans [PDF]

The Journal of Infectious Diseases, 2013
The study of the human virome is still in its infancy, especially with regard to the viral content of the blood of people who are apparently disease free. In this study, the genome of a new giant virus that is related to the amoeba-infecting pathogen Marseillevirus was recovered from donated blood, using high-throughput sequencing.

Diversity of Amoeba-Associated Giant Viruses Isolated in Algeria

Diversity, 2020
The discovery of several giant amoeba viruses has opened up a novel area in the field of virology. Despite this, knowledge about ecology of these viruses remains patchy. In this study, we aimed to characterize the diversity of giant viruses in Algeria by

First Isolation of a Marseillevirus in the Diptera Syrphidae Eristalis tenax [PDF]

Intervirology, 2013
<b><i>Objective:</i></b> Giant viruses and amoebae are common in freshwater, where they can coexist with various insects. We screened insect larvae to detect giant viruses using a high-throughput method. <b><i>Methods:</i></b> We analyzed 86 <i>Eristalis tenax</i> larvae obtained from stagnant

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

PLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

The genomic and phylogenetic analysis of Marseillevirus cajuinensis raises questions about the evolution of Marseilleviridae lineages and their taxonomical organization. [PDF]

J Virol
ABSTRACT Marseilleviruses (MsV) are a group of viruses that compose the Marseilleviridae family within the Nucleocytoviricota phylum. They have been found in different samples, mainly in freshwater. MsV are classically organized into five phylogenetic lineages (A/B/C/D/E), but the current taxonomy does

The Large Marseillevirus Explores Different Entry Pathways by Forming Giant Infectious Vesicles [PDF]

Journal of Virology, 2016
ABSTRACT Triggering the amoebal phagocytosis process is a sine qua non condition for most giant viruses to initiate their replication cycle and consequently to promote their progeny formation. It is well known that the amoebal phagocytosis process requires the recognition of

Marseillevirus, Blood Safety, and the Human Virome [PDF]

Journal of Infectious Diseases, 2013
range from familiar viruses that can infect humans and other vertebrates, such as those of the Poxviridae and Asfarviridae (the cause of African swine fever) families, respectively, to poorly understood viruses that seem to primarily infect insects, Paramecium, algae, or, as in the case of Marseilleviridae, amoebae.

Lausannevirus Encodes a Functional Dihydrofolate Reductase Susceptible to Proguanil. [PDF]

, 2017
Lausannevirus belongs to the family Marseilleviridae within the group of nucleocytoplasmic large DNA viruses (NCLDVs). These giant viruses exhibit unique features, including a large genome, ranging from 100 kb to 2.5 Mb and including from 150 to more ...

Isolation and Quantification of Mimivirus-Like and Marseillevirus-Like Viruses from Soil Samples in An Aboriginal (Orang asli) Village in Peninsular Malaysia. [PDF]

Intervirology, 2019
The giant amoebal viruses of Mimivirus and Marseillevirus are large DNA viruses and have been documented in water, soil, and sewage samples. The trend of discovering these giant amoebal viruses has been increasing throughout Asia with Japan, India, and Saudi Arabia being the latest countries to document the presence of these viruses.
