Complete Genome Sequence of a Novel Natural Recombinant Porcine Reproductive and Respiratory Syndrome Virus Isolated from a Pig Farm in Yunnan Province, Southwest China

ABSTRACT YN-2011 is a highly pathogenic North American porcine reproductive and respiratory syndrome virus (PRRSV). Unlike previously described PRRSVs, which contained a 30-amino-acid deletion in NS2, YN-2011 had no amino acid deletions or insertions but had several new mutations in NS2. Here, we announce the complete genome sequence of YN-2011.
