An Optimized Metabarcoding Method for Mimiviridae [PDF]

Microorganisms, 2020
Mimiviridae is a group of viruses with large genomes and virions. Ecological relevance of Mimiviridae in marine environments has been increasingly recognized through the discoveries of novel isolates and metagenomic studies.

A Functional K⁺ Channel from Tetraselmis Virus 1, a Member of the Mimiviridae [PDF]

Viruses, 2020
Potassium ion (K+) channels have been observed in diverse viruses that infect eukaryotic marine and freshwater algae. However, experimental evidence for functional K+ channels among these alga-infecting viruses has thus far been restricted to members of ...

Mimiviridae, Marseilleviridae, and virophages as emerging human pathogens causing healthcare-associated infections

GMS Hygiene and Infection Control, 2014
[english] Aim: During the last decade it became obvious that viruses belonging to and families (order Megavirales), may be potential causative agents of pneumonia. Thus, we have performed a review of the association of , , and virophages with pneumonia,

Pacmanvirus isolated from the Lost City hydrothermal field extends the concept of transpoviron beyond the family Mimiviridae [PDF]

ISME Journal
Abstract The microbial sampling of submarine hydrothermal vents remains challenging, with even fewer studies focused on viruses. Here we report what is to our knowledge the first isolation of a eukaryotic virus from the Lost City hydrothermal field, by co-culture with the laboratory host Acanthamoeba castellanii.

Presence of CRISPR CAS-Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells. [PDF]

Biomed Res Int, 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

Comparative glycomic analysis of Mimiviridae and Marseilleviridae uncovers host-related and lineage-specific glycosylation. [PDF]

J Biochem
Abstract Giant viruses encode unusual glycosylation machinery distinct from their amoebal hosts, raising fundamental questions about how their glycans are synthesized and diversified. Here, we present a comparative glycomic analysis of mimivirus, tokyovirus and hokutovirus, together with their common host Acanthamoeba castellanii. The

Commensalism in the Mimiviridae giant virus family [PDF]

The ISME Journal, 2019
Abstract Acanthamoeba-infecting Mimiviridae belong to three clades: Mimiviruses (A), Moumouviruses (B) and Megaviruses (C). The uniquely complex mobilome of these giant viruses includes virophages and linear 7 kb-DNA molecules called “transpovirons”.

Gut Virome: What's the Role in Irritable Bowel Syndrome? [PDF]

Rev Med Virol
ABSTRACT The gut virome, an integral but still poorly understood component of the gut microbiota, is emerging as an important player in the pathophysiology of irritable bowel syndrome (IBS). Recent evidence suggests that alterations in virome diversity and phage–bacteria interactions contribute to gut dysbiosis, immune modulation and gut barrier ...

A Decade of Improvements in Mimiviridae and Marseilleviridae Isolation from Amoeba [PDF]

Intervirology, 2013
Since 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 additional strains. By first focusing on cooling towers using our original time-consuming procedure, we were able to isolate a ...

Multiple infections of zoonotic pathogens in wild Brandt's voles (Lasiopodomys brandtii)

Veterinary Medicine and Science, Volume 9, Issue 5, Page 2201-2211, September 2023., 2023
Our research revealed the viral and bacterial diversity in wild Brandt's voles. The characterization and distinctive lineage of some rodent‐specific viruses (Cytomegalovirus, PestVs and Lentiviruses) and rodent‐borne bacteria (Leptospira interrogans and Vibrio cholerae) indicates that wild Brandt's voles may harbor a diversity of viruses and bacteria ...
