Serosurvey of three virus infections in reindeer in northern Norway and Svalbard

Sera from 326 Norwegian reindeer (NR) and from 40 Svalbard reindeer (SR) were examined for antibodies to reindeer herpesvirus (RHV), bovine viral diarrhoea virus (BVDV) and parainfulenza type 3 virus (PIV-3). No antibodies to any of these three viruses were detected in sera from SR. Sixty-three percent of sera from 101 adult NR (> 12 months old) and 15% of 225 NR calves (6 months old) had antibodies to RHV; corresponding values for BVDV were 41% and 6%, respectively. Twenty-seven percent of adult NR and 1% of NR calves had antibodies to both viruses. No antibodies to PIV-3 were detected in any NR sera.
