Pathogenicity of 2 Porcine Deltacoronavirus Strains in Gnotobiotic Pigs
porcine deltacoronavirus, PDCoV, coronavirus, Viruses, strains, strain OH-FD22
To verify whether porcine deltacoronavirus infection induces disease, we inoculated gnotobiotic pigs with 2 virus strains (OH-FD22 and OH-FD100) identified by 2 specific reverse transcription PCRs. At 21–120 h postinoculation, pigs exhibited severe diarrhea, vomiting, fecal shedding of virus, and severe atrophic enteritis. These findings confirm that these 2 strains are enteropathogenic in pigs.
