Importantly, recombinant PEDV was rapidly transmitted to uninoculated pigs via indirect contact, demonstrating virulence and efficient transmission while replicating phenotypes seen in the wild-type virus. While the recombinant icPEDV replicated the clinical phenotypes of parental PC22A in vivo, icPEDV-⌬ORF3-RFP infection resulted in a partial attenuation in pigs based on lower diarrhea scores. Both the parental PEDV PC22A strain and its derivative recombinant cloned virus were genetically stable and fully pathogenic in neonatal gnotobiotic pigs, demonstrating that icPEDV provides not only a strategy that allows for the systematic evaluation of the role of viral genes in pathogenesis, tropism, and virulence but also a translational platform for the development of rationally attenuated live virus vaccines. ./cache/cord-348669-mizygp4j.txt ./txt/cord-348669-mizygp4j.txt
