Key result
The full-length cDNA of an infectious PTV2 GX/2020 clone was successfully constructed, exhibiting viral growth properties consistent with the parental virus.
Why the study?
Porcine teschovirus is a causative agent of polioencephalomyelitis, encephalomyelitis, reproductive disorders, and gastrointestinal and respiratory diseases in swine.
The successful isolation of PTV2 and creation of a reverse-genetic platform provides a foundation for studying the pathogenic mechanisms of porcine teschovirus.
Enables mechanistic studies of PTV2; leaves open its utility for swine disease models and interventions.
Porcine teschovirus (PTV) is a causative agent of polioencephalomyelitis, encephalomyelitis, reproductive disorders and gastrointestinal and respiratory diseases in swine. In the present study, the PTV2 GX/2020 strain was isolated from pig intestinal tissue through the use of ST cells. Phylogenetic analysis of VP1 nucleotide sequences indicated that the GX/2020 isolate is closely related to PTV2. Furthermore, the full-length cDNA of an infectious GX/2020 clone was constructed using seamless ligation technology. The genome sequence of the rescued virus is largely consistent with the sequence of the parental virus, and it exhibits viral growth properties. The PTV2 virus was successfully isolated in the present study, and the reverse-genetic platform provides a foundation for studies of the pathogenic mechanisms of porcine teschovirus.
