Abstract

The etiology of a large proportion of gastrointestinal illness is unknown. In this study, random Sanger sequencing and pyrosequencing approaches were used to analyze fecal specimens from a gastroenteritis outbreak of unknown etiology in a child care center. Multiple sequences with limited identity to known astroviruses were identified. Assembly of the sequences and subsequent reverse transcription-PCR (RT-PCR) and rapid amplification of cDNA ends generated a complete genome of 6,586 nucleotides. Phylogenetic analysis demonstrated that this virus, named astrovirus VA1 (AstV-VA1), is highly divergent from all previously described astroviruses. Based on RT-PCR, specimens from multiple patients in this outbreak were unequivocally positive for Ast-VA1.

  • Astroviruses have a broad host range and are frequently detected in the faeces of mammals, birds, and humans with gastroenteritis.

    “Astroviruses have a broad host range (Donato and Vijaykrishna 2017) and are frequently detected in the faeces of mammals, birds, and humans with gastroenteritis (Finkbeiner et al. 2009; De Benedictis et al. 2011).”

    From Red fox viromes in urban and rural landscapes (2020) · cites this paper as Finkbeiner et al. 2009

    The cited paper supports detection in humans: its Abstract reports astrovirus VA1 in fecal samples from a gastroenteritis outbreak and describes human astroviruses associated with diarrhea. It also notes that astroviruses infect a variety of species, but does not establish that they are frequently detected in the feces of mammals and birds with gastroenteritis. The sentence attributes the separate broad-host-range clause to Donato and Vijaykrishna, not to this paper. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
