Early-Phase Drive to the Precursor Pool: Chloroviruses Dive into the Deep End of Nucleotide Metabolism

open access: yesViruses, 2023
Viruses face many challenges on their road to successful replication, and they meet those challenges by reprogramming the intracellular environment. Two major issues challenging Paramecium bursaria chlorella virus 1 (PBCV-1, genus Chlorovirus, family ...

Herpes Simplex Virus 1 Manipulates Host Cell Antiviral and Proviral DNA Damage Responses

open access: yesmBio, 2021
We investigated the relationship between the DNA damage response, a collection of vital cellular pathways that repair potentially lethal damage to the genome, and the DNA virus herpes simplex virus 1. We found that infection by the virus triggers the DNA

Novel Viruses in Mosquitoes from Brazilian Pantanal

open access: yesViruses, 2019
Viruses are ubiquitous and diverse microorganisms arising as a result of interactions within their vertebrate and invertebrate hosts. Here we report the presence of different viruses in the salivary glands of 1657 mosquitoes classified over 28 culicinae ...

Isolation of a natural DNA virus of Drosophila melanogaster, and characterisation of host resistance and immune responses. [PDF]

open access: yesPLoS Pathogens, 2018
Drosophila melanogaster has played a key role in our understanding of invertebrate immunity. However, both functional and evolutionary studies of host-virus interaction in Drosophila have been limited by a dearth of native virus isolates.

The white spot syndrome virus DNA genome sequence [PDF]

open access: yes, 2001
White spot syndrome virus (WSSV) is at present a major scourge to worldwide shrimp cultivation. We have determined the entire sequence of the double-stranded, circular DNA genome of WSSV, which contains 292,967 nucleotides encompassing 184 major open ...

The main DNA viruses significantly affecting pig livestock

open access: yesJournal of Veterinary Research, 2020
Swine DNA viruses have developed unique mechanisms for evasion of the host immune system, infection and DNA replication, and finally, construction and release of new viral particles.

Evaluating vertical transmission of sexually transmitted infections to newborns

open access: yesJournal of Infection in Developing Countries, 2021
Introduction: Sexually transmitted infections are among the most frequent infections affecting pregnant women. We assessed the transmission of hepatitis B virus, human immunodeficiency virus type 1 and Treponema pallidum to newborns from infected ...

Biochemical characterization of novel retroviral integrase proteins. [PDF]

open access: yesPLoS ONE, 2013
Integrase is an essential retroviral enzyme, catalyzing the stable integration of reverse transcribed DNA into cellular DNA. Several aspects of the integration mechanism, including the length of host DNA sequence duplication flanking the integrated ...

Influence of retinoblastoma-related gene silencing on the initiation of DNA replication by African cassava mosaic virus Rep in cells of mature leaves in Nicotiana benthamiana plants [PDF]

open access: yes, 2011
Background Geminiviruses mainly infect terminally differentiated tissues and cells in plants. They need to reprogramme host cellular machinery for DNA replication.
