Abstract
Here, we report the isolation of a type 1 porcine reproductive and respiratory syndrome virus (PRRSV) strain from a clinical outbreak of severe respiratory problems and high fever. Next-generation sequencing was used to determine the complete genome sequence of the isolate (9625/2012). The virus belongs to a new branch within subtype 1, clade D, and shows the highest similarity to PRRSV Olot/1991 and to the Amervac vaccine strain. Mutation analysis of 9625/2012 revealed no evidence of recombination but did show a high proportion of amino acid substitutions in the putative neutralizing epitopes, suggesting an important role of selective immune pressure in the evolution of PRRSV 9625/2012.
