High Prevalence of a Novel Circovirus in the European Hedgehog (<i>Erinaceus europaeus</i>), a Common Species in Decline. [PDF]

Transbound Emerg Dis
Hedgehog (Erinaceus europaeus) declines in western Europe have been associated with the emergence of Hedgehog diphtheric disease (HDD), with a probable multifactorial, yet unidentified etiology. We used metagenomic sequencing of cell‐free DNA (cfDNA) in hedgehog blood to identify possible causes of HDD.

High prevalence of cyclovirus Vietnam (CyCV-VN) in plasma samples from Madagascan healthy blood donors

Infection, Genetics and Evolution, 2018
Cycloviruses, small ssDNA viruses belonging to the Circoviridae family, have been suggested as possible causes of enteric, respiratory and neurological disorders in human patients. One of these species, cyclovirus-Vietnam (CyCV-VN), initially isolated from cerebrospinal fluid samples of patients with unexplained neurological disorders, has since been ...

Gut Virome of Tibetan Pigs Reveals the Diversity, Composition, and Distribution of Potential Novel Viruses/Variants. [PDF]

Transbound Emerg Dis
As a local breed adapted to the extreme environment of the Tibetan Plateau, Tibetan pigs have not yet been systematically characterized in terms of their gut viral communities. In this study, we applied viral metagenomics to sequence fecal samples from 191 Tibetan pigs (including both healthy and diarrheal individuals) across four farms in Nyingchi ...

Assessment on the efficacy of methods 2 to 5 and method 7 set out in Commission Regulation (EU) No 142/2011 to inactivate relevant pathogens when producing processed animal protein of porcine origin intended to feed poultry and aquaculture animals

EFSA Journal, Volume 21, Issue 7, July 2023., 2023
Abstract An assessment was conducted on the level of inactivation of relevant pathogens that could be present in processed animal protein of porcine origin intended to feed poultry and aquaculture animals when methods 2 to 5 and method 7, as detailed in Regulation (EU) No 142/2011, are applied.

The seminal plasma microbiome of men with testicular germ cell tumours described by small RNA sequencing

Andrology, Volume 11, Issue 4, Page 756-769, May 2023., 2023
Abstract Background It has been estimated that microorganisms are involved in the pathogenesis of approximately 20% of all cancers. Testicular germ cell tumours (TGCTs) are the most common type of malignancy in young men and arise from the precursor cell, germ cell neoplasia in situ (GCNIS).

The Genetic Diversity and Interspecific Transmission of Circovirus in Rhizomys sinensis in Guangdong, Southern China

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
Circoviruses are a group of small circular, single‐stranded DNA viruses that belong to the family Circoviridae. They are known to infect a wide variety of animals. Rhizomys sinensis is a species of rodent that is the reservoir of many zoonotic pathogens. Our previous study identified many sequencing reads mapped to the genome of viruses in Circoviridae

Emergence of porcine circovirus‐like viruses associated with porcine diarrheal disease in China

Transboundary and Emerging Diseases, Volume 68, Issue 6, Page 3167-3173, November 2021., 2021
Abstract Background The circular replication‐associated protein (Rep)‐encoding single‐stranded (CRESS) DNA virus emergence in diverse host has been associated with severe disease. Porcine circovirus‐like virus (Po‐Circo‐like [PCL] virus) is a CRESS DNA virus, the prevalence and pathogenicity of which are rarely studied.

A Novel Coronavirus and a Broad Range of Viruses in Kenyan Cave Bats

Viruses, 2022
Background and Methods: To investigate virus diversity in hot zones of probable pathogen spillover, 54 oral-fecal swabs were processed from five bat species collected from three cave systems in Kenya, using metagenome sequencing.

Metagenomic analysis reveals differences in the co-occurrence and abundance of viral species in SARS-CoV-2 patients with different severity of disease

BMC Infectious Diseases, 2022
Background SARS-CoV-2 infections have a wide spectrum of clinical manifestations whose causes are not completely understood. Some human conditions predispose to severe outcome, like old age or the presence of comorbidities, but many other facets ...
