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

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 ...

Revolving ATPase motors as asymmetrical hexamers in translocating lengthy dsDNA via conformational changes and electrostatic interactions in phi29, T7, herpesvirus, mimivirus, E. coli, and Streptomyces

Exploration, Volume 3, Issue 2, April 2023., 2023
The revolving DNA motors of ATPase have been found in viruses (phi29, T7, herpesvirus, and mimivirus) and bacteria (E. coli and Streptomyces). The motors made of asymmetrical 6 subunits translocate lengthy double‐stranded (ds)DNA. The dsDNA is moved in a circular motion around the inner surface of the motor channel subunits.

Covariance of Marine Nucleocytoplasmic Large DNA Viruses with Eukaryotic Plankton Communities in the Sub-Arctic Kongsfjorden Ecosystem: A Metagenomic Analysis of Marine Microbial Ecosystems

Microorganisms, 2023
Nucleocytoplasmic large DNA viruses (NCLDVs) infect various marine eukaryotes. However, little is known about NCLDV diversity and their relationships with eukaryotic hosts in marine environments, the elucidation of which will advance the current ...

Metabolic reconstruction of the near complete microbiome of the model sponge Ianthella basta

Environmental Microbiology, Volume 25, Issue 3, Page 646-660, March 2023., 2023
Abstract Many marine sponges host highly diverse microbiomes that contribute to various aspects of host health. Although the putative function of individual groups of sponge symbionts has been increasingly described, the extreme diversity has generally precluded in‐depth characterization of entire microbiomes, including identification of syntrophic ...

Identification and Genomic Characterization of Anelloviruses in Patients with Chronic Lymphocytic Leukemia

Journal of Clinical Pharmacy and Therapeutics, Volume 2023, Issue 1, 2023., 2023
Purpose. Metagenomics has revealed that, in addition to the digestive tract, certain viruses are also commonly found in human blood. In order to explore and monitor potential novel viruses, three serum samples of patients with chronic lymphocytic leukemia were collected at the No. 2 People’s Hospital of Changshu City, China. Materials and Methods.

Tracing the Origin of Genotype II African Swine Fever Virus in China by Genomic Epidemiology Analysis

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
The pandemic spread of African swine fever (ASF) has caused serious effects on the global pig industry. Virus genome sequencing and genomic epidemiology analysis play an important role in tracking the outbreaks of the disease and tracing the transmission of the virus.

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

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 ...

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

ISME J
International audienceThe microbial sampling of submarine hydrothermal vents remains challenging, with even fewer studies focused on viruses. Here we report the first isolation of a eukaryotic virus from the Lost City hydrothermal field, by co-culture ...
