2023, Advances in Virus ResearchIdentification of a novel astrovirus in goats in China
2021, Infection, Genetics and EvolutionCitation Excerpt :Based on the genetic distances of the entire capsid protein sequences, five potential AstV genotype species (MAstV 13, MAstV 24, Caprine Astrovirus G3.1, Caprine Astrovirus G5.1, and a bovine-related AstV genotype species), have been detected in goats or sheep (Jonassen et al., 2003; Reuter et al., 2012; Kauer et al., 2019). Two genotype species, MAstV 13 and MAstV 24, were only detected in sheep (Jonassen et al., 2003; Reuter et al., 2012); two genotype species, Caprine Astrovirus G3.1, and the bovine-related AstV genotype species, were only detected in goats (Kauer et al., 2019); and Caprine Astrovirus G5.1 was detected both in goats and sheep (Kauer et al., 2019). Although OvAstV-1 (MAstV 13) was identified as an enteric pathogen in lambs (Snodgrass and Gray, 1977; Snodgrass et al., 1979; Gray et al., 1980), the pathogenicity of the other four potential AstV genotype species remains unknown due to the lack of cell culture systems and epidemiological data.
The Expanding Field of Mammalian Astroviruses: Opportunities and Challenges in Clinical Virology
2017, Advances in Virus ResearchFull-genome based molecular characterization of encephalitis-associated bovine astroviruses
2016, Infection, Genetics and EvolutionCitation Excerpt :The 5′ UTR of astroviruses varies between 11 and 85 nt in length and little is known about its structure and function. In AAstV a conserved stem-loop structure of 8–18 nt within the 5′ UTR has been proposed to function as a promoter element (Jonassen et al., 2003), however, to our knowledge a similar structure has so far not been reported for MAstV. In the BoAstV CH13/NeuroS1 strains of the present study, a prominent stem-loop structure was predicted for the first 41 nt of the genome.
