Genetic heterogeneity and recombination in human type 2 astroviruses [PDF]

, 2012
Novel lineages of human astrovirus (HAstV) types 2, 2c, and 2d have been identified. Upon sequencing of the 3= end of the genome, the type 2c and 2d HAstVs were found to be open reading frame 1b (ORF1b)-ORF2 recombinant, with ORF1b being derived from ...

Novel Human Astroviruses: Prevalence and Association with Common Enteric Viruses in Undiagnosed Gastroenteritis Cases in Spain

Viruses, 2019
A remarkable percentage of acute gastroenteritis cases remain etiologically undiagnosed. The aim of the study was to determine the prevalence of common and emerging enteric viruses, such as novel human astroviruses, among undiagnosed samples from ...

Astroviruses [PDF]

, 2003
Human astroviruses are members of the Astroviridae family. They are non-enveloped viruses possessing a single-stranded RNA of positive polarity as their genome. The development of sensitive tests for the presence of astrovirus-for example, using group reactive monoclonal antibodies-has led to the conclusion that astroviruses are the cause of more cases

Astroviruses

, 2008
Astroviruses are positive-sense, single-stranded RNA viruses. Their genomes contain three open reading frames, but the exact number of encoded proteins remains unknown. Astroviruses were originally identified in association with childhood diarrhea; subsequently, they have been identified as a common enteric virus infecting children under the age of 2 ...
