Abstract

Bovine viral diarrhoea virus (BVDV) and Border disease virus (BDV) were investigated at the wildlife-livestock interface in the distribution area of chamois in the Cantabrian Mountains, North-Western Spain. From 2010 to 2014, sera from sympatric wild (n=167) and domestic (n=272) ruminants were analysed for pestivirus antibodies by cELISA, virus neutralisation test (VNT) and for the presence of pestiviral RNA using a reverse transcription (RT)-PCR. Results showed a higher seroprevalence in cattle (59.4 per cent, 13/13 of herds) than in domestic small ruminants (5.9 per cent sheep, 2/8 of flocks; 0 per cent goats of 4 flocks) and wildlife (10.8 per cent in red deer, 0 per cent in roe deer and 0 per cent in Cantabrian chamois). High VNT titres were detected in two cattle herds, suggesting the circulation of BVDV-1 and BVDV-2 strains. BVDV-1 RNA was detected in one cattle calf by RT-PCR and sequencing. Conversely to other similar grazing systems, sheep flocks did not play a relevant role in the pestivirus epidemiology in this region. Pestivirus infections in wild ruminants were sporadic and most probably dependent on a domestic source.
