Abstract

The complete genome sequence of Seneca Valley virus (SVV), a single-stranded RNA virus that causes porcine vesicular disease in China, has been sequenced and analyzed. This Chinese isolate shares 94.4 to 97.1% sequence identity to another 8 strains from Canada, Brazil, and the United States. This is the first report of SVV infecting swine in China.

Highlights

  • The complete genome sequence of Seneca Valley virus (SVV), a single-stranded RNA virus that causes porcine vesicular disease in China, has been sequenced and analyzed

  • Seneca Valley virus (SVV), which causes porcine idiopathic vesicular disease, was first identified in either contaminated fetal bovine serum or porcine trypsin during the cultivation of PER.C6 cells [1] and isolated from pigs displaying suspicious vesicular disease when pigs were imported to the United States from Canada in 2007 [2, 3]

  • The complete genome of SVV CH-01-2015 was generated with reverse transcriptase PCR (RT-PCR) using 7 pairs of primers amplifying 7 overlapped fragments
