Detection and genetic characterization of porcine pegivirus in pigs in the United States.

Using next-generation sequencing on vesicular swab and serum from swine from the USA exhibiting lameness and vesicles, porcine pegivirus (PPgV) was first identified and genetically characterized in the United States. Further screening using RT-PCR revealed that 24 of 159 (15.1%) serum samples were positive for PPgV. Future studies are needed to understand clinical impacts of the virus.
