ICTV Virus Taxonomy Profile: Retroviridae 2021

The Journal of general virology, 2021
Viruses in the family Retroviridae are found in a wide variety of vertebrate hosts. Enveloped virions are 80–100 nm in diameter with an inner core containing the viral genome and replicative enzymes. Core morphology is often characteristic for viruses within the same genus.

Relationships of gag-pol diversity between Ty3/Gypsy and Retroviridae LTR retroelements and the three kings hypothesis [PDF]

BMC Evolutionary Biology, 2008
Background The origin of vertebrate retroviruses (Retroviridae) is yet to be thoroughly investigated, but due to their similarity and identical gag-pol (and env) genome structure, it is accepted that they evolve from Ty3/Gypsy LTR retroelements the ...

Mucosal DNA and RNA virome alterations and their interactions with human RNA and microRNA transcriptomes in colorectal polyps [PDF]

eGastroenterology
Background Imbalance in the gut microbiome is known to play a role in colorectal cancer (CRC) development. Recent studies observed alterations in the faecal and mucosal DNA virome in CRC, but the role of mucosal virome including both DNA and RNA viruses ...

Fecal Virome of Southeastern Maned Sloth (Bradypus crinitus) (Pilosa: Bradypodidae) [PDF]

Genetics and Molecular Biology
We report a viral metagenomic analysis of fecal samples from Bradypus crinitus (Pilosa: Bradypodidae), a recently described sloth species that occurs in the Atlantic Forest of Espírito Santo and Rio de Janeiro states, Southeast Brazil.

Viruses in saliva from sanctuary chimpanzees (Pan troglodytes) in Republic of Congo and Uganda

PLoS ONE, 2023
Pathogen surveillance for great ape health monitoring has typically been performed on non-invasive samples, primarily feces, in wild apes and blood in sanctuary-housed apes. However, many important primate pathogens, including known zoonoses, are shed in

Antiviral and virucidal activity of sodium deoxyribonucleate and its complex with iron against viruses of different kingdoms and families

Вопросы вирусологии, 2023
Introduction. The urgent problem of modern medicine is the fight against acute respiratory viral infections (ARVI). To combat ARVI, drugs of wide antiviral potency are needed, as well as immunomodulating drugs. Such antiviral and immunomodulatory effects
