TLDR
Examination of the intestinal contents of free-living Oryzomys nigripes rats by PAGE revealed two sharply defined bands that could be stained by ethidium bromide or by silver nitrate with comparable intensities, suggesting that these particles represent an as yet undescribed virus with a bisegmented double-stranded RNA genome, for which the name 'picobirnavirus' is proposed.
Abstract
Examination of the intestinal contents of free-living Oryzomys nigripes rats by PAGE revealed two sharply defined bands that could be stained by ethidium bromide or by silver nitrate with comparable intensities. The molecules forming these bands were susceptible to digestion by pancreatic RNase A but not by RNase T1 or by DNase I. Their lengths were estimated to be about 2.6 and 1.5 kbp, respectively, by comparison with rotavirus SA11 genome segments. They cosedimented in CsCl gradients at a density of 1.39 to 1.40 g/ml, together with uniform particles approximately 35 nm in diameter with indistinct surface structure. It is suggested that these particles represent an as yet undescribed virus with a bisegmented double-stranded RNA genome, for which the name 'picobirnavirus' is proposed.

Molecular characterization of a novel picobirnavirus in a chicken.

TL;DR: This is the first full-genome picobirnavirus sequence from a broiler breeder chicken, but the pathogenicity of this virus is still questionable.

Rotavirus, Caliciviruses, Astroviruses, Enteric Adenoviruses, and Other Viruses Causing Acute Gastroenteritis†

Tibor Farkas, +1 more
TL;DR: The recent introduction of rotavirus vaccines to the international markets is a promising start and hopefully will be followed by similar strategies for other viral causes of acute gastroenteritis, and this chapter also talks about other enteropathogenic viruses such as coronaviruses and toroviruses, picobirnavIRuses, and aichi virus.

VI, 2. Molecular characterization and epidemiology of picobirnaviruses

TL;DR: Evidence supporting picobirnavirus infection of vertebrates includes the detection of serologic responses to picOBirnaviruses in pigs and rabbits and limited replication of picobIRnavirus strains from guinea pigs in first passage attempts in human and animal cell lines.

Metagenome-Assembled Viral Genomes Analysis Reveals Diversity and Infectivity of the RNA Virome of Gerbillinae Species

TL;DR: A high degree of biodiversity of Retro-, Flavi-, Pneumo-, and Picobirnaridae families and other zoonotic viruses in gerbils are found, indicating that zoonosis viruses are a common presence in Gerbils from Xinjiang, China.

TL;DR: A rapid simple technique based on the sensitive detection of rotavirus double-stranded RNA genome segments separated in polyacrylamide gels, which is comparable with that of electron microscopy or enzyme-linked immunosorbent assay.

Biophysical and biochemical characterization of five animal viruses with bisegmented double-stranded RNA genomes.

TL;DR: Infectious pancreatic necrosis virus of fish, infectious bursal disease virus of chickens, Tellina virus and oyster virus of bivalve molluscs, and drosophila X virus of Drosophila melanogaster are naked icosahedral viruses with an electron microscopic diameter of 58 to 60 nm as mentioned in this paper.

TL;DR: Tryptic peptide comparisons of 125I-labeled virion proteins showed that five viruses are different from each other, although there was considerable overlap in the peptide maps of the three aquatic viruses, indicting a degree of relatedness.
