| Abstract: | Porcine Pegivirus (PPgV) and Atypical Porcine Pestivirus (APPV) are two recently identified porcine viruses. In this study, the identification of two viruses by metagenomic sequencing, and a duplex semi‐quantitative RT‐PCR was developed to detect these pathogens simultaneously. The PPgV strain Minnesota‐1/2016 had a 95.5%–96.3% nucleotide identity and clustered with the recently identified US PPgV strains, which is a distant clade from the German PPgV strains. The APPV strain Minnesota‐1/2016 shared an 87.3%–92.0% nucleotide identity with the other global APPV strains identity but only shared an 82.8%–83.0% nucleotide identity with clade II consisting of strain identified in China. Detection of both PPgV and APPV was 9.0% of the diagnostic cases. Co‐infection of PPgV and APPV was identified in 7.5% of the diagnostic cases. The occurrence and genetic characterization of PPgV and APPV further enhance our knowledge regarding these new pathogens in the United States. |
