Abstract

Thirty swine samples collected from different regions of Namibia between 2019 and 2020 were screened for the presence of porcine parvovirus 1 (PPV1) by PCR. Eleven samples (37%) were positive. Phylogenetic analysis of a partial sequence of the structural protein gene (VP2) identified two distinct clusters, one which contained sequences that were highly similar to PPV1 previously identified in warthogs in Namibia. These results indicate possible PPV1 transmission between warthogs and domestic pigs and highlight the importance of wildlife as sources of pathogens.
