Genetic and Pathogenic Characterization of a Porcine Deltacoronavirus Strain Isolated in Zhejiang Province, China.

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
Porcine deltacoronavirus (PDCoV) has emerged as a significant pathogen in swine, affecting animal health and posing potential risks for cross-species transmission. In this study, we successfully isolated a PDCoV strain named HZYH-2019 from the feces of diarrheal sows in Zhejiang Province, China. The viral growth curve demonstrated strong adaptation of this strain to cells, with particularly high replication efficiency observed in LLC-PK1 cells. Genomic analysis revealed a high degree of nucleotide sequence similarity between PDCoV HZYH-2019 and other PDCoV strains. A notable mutation at the tenth amino acid position of the spike protein altered the predicted signal peptide position. Phylogenetic analyses indicated that PDCoV HZYH-2019 clustered with Chinese strains, while four Chinese strains were grouped within the American spectrum, suggesting that the pork trade may facilitate cross-border virus transmission. Analysis of known PDCoV strains inferred that PDCoV may have originated in Asia and that there is cross-species transmission from birds to mammals. Notably, PDCoV HZYH-2019 caused diarrhea in piglets without mortality, although significant intestinal lesions were observed. These findings enhance our understanding of PDCoV's biological behavior and zoonotic potential, informing the development of effective vaccines and control measures to manage future outbreaks.
