Neighbour-joining tree of A: ORF5 (N = 248) and B: ORF7 (N = 288) of PRRSV virus isolates used in this study as well as Lelystad strain (Genbank accession number M96262). In brackets the sample provenance is reported (farm number). One part of each tree was zoomed to show the strong clustering of ORF5 and ORF7 by farm.
