Unmapped RNA Virus Diversity in Termites and their Symbionts. [PDF]

Viruses, 2020
Despite their ecological importance, nothing is known about the diversity and abundance of RNA viruses in termites (Termitoidae). We used a metatranscriptomics approach to determine the RNA virome structure of 50 diverse species of termite that differ in both phylogenetic position and colony composition.

Virome analysis of an ectomycorrhizal fungus Suillus luteus revealing potential evolutionary implications

Frontiers in Cellular and Infection Microbiology, 2023
Suillus luteus is a widespread edible ectomycorrhizal fungus that holds significant importance in both ecological and economic value. Mycoviruses are ubiquitous infectious agents hosted in different fungi, with some known to exert beneficial or ...

Human immunodeficiency virus infection predictors and genetic diversity of hepatitis B virus and hepatitis C virus co-infections among drug users in three major Kenyan cities

Southern African Journal of HIV Medicine, 2018
Background: Drug users act as reservoirs and transmission channels for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections to the general population worldwide. Periodic epidemiological studies to monitor the

Virus discovery and recent insights into virus diversity in arthropods

Current Opinion in Microbiology, 2013
Recent studies on virus discovery have focused mainly on mammalian and avian viruses. Arbovirology with its long tradition of ecologically oriented investigation is now catching up, with important novel insights into the diversity of arthropod-associated viruses. Recent discoveries include taxonomically outlying viruses within the families Flaviviridae,

Mixed Infection and the Genesis of Influenza Virus Diversity [PDF]

Journal of Virology, 2009
ABSTRACT The emergence of viral infections with potentially devastating consequences for human health is highly dependent on their underlying evolutionary dynamics. One likely scenario for an avian influenza virus, such as A/H5N1, to evolve to one capable of human-to-human transmission is through the acquisition of genetic material from the A/

Sequence diversity of hepatitis D virus in Mongolia

Frontiers in Medicine, 2023
IntroductionThe Hepatitis Delta Virus (HDV) is a defective, single-stranded RNA virusoid encoding for a single protein, the Hepatitis Delta Antigen (HDAg), which requires the hepatitis B virus (HBV) envelope protein (HBsAg) for its transmission. Currently, hepatitis D is the most aggressive form of viral hepatitis and treatment options are limited ...

Influenza A Virus Diversity and Transmission in Exhibition Swine [PDF]

Journal of Infectious Diseases, 2015
(See the major article by Nelson et al on pages 173–82.) Swine are permissive to infections with both avian and human influenza A viruses, facilitating genomic reassortment among viruses from multiple host species. As a result, swine have been identified as mixing vessels for influenza A viruses and a source of emergence for novel viruses, including

Metatranscriptome-based strategy reveals the existence of novel mycoviruses in the plant pathogenic fungus Fusarium oxysporum f. sp. cubense

Frontiers in Microbiology, 2023
Fusarium oxysporum f. sp. cubense (Foc) is a devastating plant pathogen that caused a great financial loss in the banana’s source area. Metatranscriptomic analysis was used to determine the diversity of mycoviruses in 246 isolates of F. oxysporum f.

Effects of Transmission Bottlenecks on the Diversity of Influenza A Virus [PDF]

Genetics, 2018
AbstractWe investigate the fate of de novo mutations that occur during the in-host replication of a pathogenic virus, predicting the probability that such mutations are passed on during disease transmission to a new host. Using influenza A virus as a model organism, we develop a life-history model of the within-host dynamics of the infection, deriving ...

Epidemiology and genetic diversity of bovine leukemia virus [PDF]

Virology Journal, 2017
Bovine leukemia virus (BLV), an oncogenic member of the Deltaretrovirus genus, is closely related to human T-cell leukemia virus (HTLV-I and II). BLV infects cattle worldwide and causes important economic losses. In this review, we provide a summary of available information about commonly used diagnostic approaches for the detection of BLV infection ...
