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.

The 4.4 Å structure of the giant Melbournevirus virion belonging to the Marseilleviridae family [PDF]

, 2021
Summary Members of Marseilleviridae , one family of icosahedral giant viruses classified in 2012 have been identified worldwide in all types of environments. The virion shows a characteristic internal membrane extrusion at the five-fold vertices of the capsid, but its structural ...

A comparative study of flow cytometry‐sorted communities and shotgun viral metagenomics in a Singapore municipal wastewater treatment plant

iMeta, Volume 1, Issue 3, September 2022., 2022
This study elucidates the practical protocol of applying fluorescence‐activated cell sorting (FACS) and metagenomics on DNA and RNA viromes. This is the first systematic analysis of viral metagenomics in a municipal wastewater treatment plant with the Modified Ludzack–Ettinger (MLE) process.

Removal of large viruses and their dispersal through fecal pellets of the appendicularian Oikopleura dioica during Emiliania huxleyi bloom conditions

Limnology and Oceanography, Volume 66, Issue 11, Page 3963-3975, November 2021., 2021
Abstract Despite their importance in shaping the structure and function of marine microbial food webs, little is known about factors regulating marine virus abundance. Previous work demonstrated clearance of laboratory‐cultured Emiliania huxleyi virus by the appendicularian Oikopleura dioica; however, the applicability of this interaction to natural ...

Cervicovaginal Human Papillomavirus Genomes, Microbiota Composition and Cytokine Concentrations in South African Adolescents

Viruses, 2023
The interaction between cervicovaginal virome, bacteriome and genital inflammation has not been extensively investigated. We assessed the vaginal DNA virome from 33 South African adolescents (15–19 years old) using shotgun DNA sequencing of purified ...

Virus-encoded histone doublets are essential and form nucleosome-like structures. [PDF]

Cell, 2021
International audienceThe organization of genomic DNA into defined nucleosomes has long been viewed as a hallmark of eukaryotes. This paradigm has been challenged by the identification of “minimalist” histones in archaea and more recently by the ...

First determination of DNA virus and some additional bacteria from Melophagus ovinus (sheep ked) in Tibet, China

Frontiers in Microbiology, 2022
Melophagus ovinus (sheep ked) is one of the common ectoparasites in sheep. In addition to causing direct damage to the host through biting and sucking blood, sheep ked is a potential vector of helminths, protozoa, bacteria, and viruses. Sheep M.

First Isolation of a Giant Virus from Wild Hirudo medicinalis Leech: Mimiviridae isolation in Hirudo medicinalis

Viruses, 2013
Giant viruses and amoebae are common in freshwater, where they can coexist with other living multicellular organisms. We screened leeches from the species Hirudo medicinalis for giant viruses. We analyzed five H. medicinalis obtained from Tunisia (3) and
