Frequent infection of wild boar with atypical porcine pestivirus (APPV)

In this study, 456 wild boar serum samples obtained from northern Germany were investigated for the presence of APPV genomes and virus‐specific antibodies. Results of real‐time RT‐PCR analyses revealed a genome detection rate of 19%. Subsequent genetic characterization of APPV (n = 12) from different hunting areas demonstrated close genetic relationship and, with exception of APPV from one location, displayed less than 3.3% differences in the analysed partial NS3 encoding region. Furthermore, indirect Erns ELISA revealed an antibody detection rate of approx. 52%, being in line with the high number of viremic wild boar. Analysis of fifteen wild boar samples from the Republic of Serbia by Erns antibody ELISA provided evidence that APPV is also abundant in wild boar populations outside Germany. High number of genome and seropositive animals suggest that wild boar may serve as an important virus reservoir for APPV.
