Metatranscriptomic identification of novel RNA viruses from raccoon dog (Nyctereutes procyonoides) feces in Japan.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The raccoon dog (Nyctereutes procyonoides), classified in the order Carnivora within the family Canidae, is native to East Asia and widely distributed throughout Japan due to its adaptability to various environments. Despite the close relationship between raccoon dogs and other animals, viruses infecting raccoon dogs have not been thoroughly investigated in Japan. In this study, we performed metatranscriptomic analyses using fecal samples collected from latrines of wild raccoon dogs in two locations on mainland Japan. Nearly complete viral genomes were identified, including viruses belonging to the genus Kobuvirus (CaKoV), an unclassified canine sapelovirus within the subfamily Ensavirinae (CaSaV), the Genius Mamastrovirus (CaAstV), unclassified hepe-astro-like virus (bastrovirus-like) (Bast-like V), and an unclassified dicistrovirus (DiciV) within the family Dicistroviridae. Phylogenetic analyses revealed that raccoon dog CaKoV, CaSaV, and CaAstV are related to canine strains but form independent clusters specific to raccoon dogs, suggesting they have evolved within this host population. Bast-like V, detected for the first time in raccoon dogs, showed high sequence identity with viruses previously identified in Chinese shrews. The shared insectivorous nature of these hosts and in silico host range predictions suggest that Bast-like Vs may originate from arthropod viruses. Although DiciV is likely of dietary origin due to its arthropod hosts, the large number of sequence reads detected and the phylogenetic clustering of raccoon dog DiciVs with mammalian DiciVs indicate the need to assess their potential infectivity in mammals and the risk of spillover. These findings suggest that raccoon dogs harbor endemic viruses within the canine population and may act as potential vectors for viruses with unknown infectivity in mammals but with spillover risk.
