Significant differences between titres against different strains in sheep, goat, cattle and Pyrenean chamois in the two study areas.

Significant differences between pairwise comparisons in titres against five pestivirus strains (one Bovine viral diarrhoea virus (BVDV) strain of type 1 (BVDV-NADL), three Border disease virus (BDV) strains of type 4 (BDV-Esp97, -Aran-1 and -Cadí-6) and one BDV strain of type 1 (BDV-137/4)) in sheep, goat, cattle and Pyrenean chamois in the two study areas.S = Sheep.G = Goat.Ca = Cattle.Ch = Chamois.aSera from VAPS were tested against BDV-4-Aran-1, while sera from CAUBS were tested against BDV-4-Cadí-6.
