Fecal viral shedding and virus distribution in piglets challenged with PDCoV-JS-2017. (A) Diarrhea of piglets in different groups. The severity of diarrhea was scored based on visual examination; 0 = normal and no diarrhea; 1 = mild and fluidic diarrhea; 2 = severe watery diarrhea; scores of 1 or more were considered diarrheic. (B) Fecal virus shedding in PDCoV-challenged piglets. (C) Virus distribution in the small intestine of piglets challenged with PDCoV. DU-P: Duodenum proximal. DU-D: Duodenum distal. JE-P: jejunum proximal. JE-D: jejunum distal. IL-P: ileum proximal. IL-D: ileum distal.
