Complete Genome Sequence of a Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus NM1 Strain from Northern China

Abstract

NM1 is a highly pathogenic North American-type porcine reproductive and respiratory syndrome virus (PRRSV). The complete genome sequence shows that NM1 shares high sequence identity (99.2 to 99.4%) to other HP-PRRSV isolates, containing two discontinuous deletions, a 1-amino-acid deletion at position 481 and a 29-amino-acid deletion at positions 533 to 651, in nonstructural protein 2.
