Phylogenetic tree based on complete PRRSV ORF5 gene nucleotide sequence of 47 PRRSV field strains and the the modified live virus (Unistrain®PRRS) used for vaccination in the study herds. The tree was generated using Neighbor-Joining method with Geneious Tree builder with bootstrats (× 1000 replicates) > 50%. The scale bare indicates the genetic distance. Different clusters are marked with different colored boxes
