Abstract

Porcine circovirus 2 (PCV-2) is the causative agent of porcine circovirus diseases (PCVD). A study was undertaken to determine whether PCV-2 was present in samples collected from commercial pigs (n = 46) and warthogs (n = 42) in Namibia between 2019 and 2020. Twenty-three of the collected samples were positive by PCR (13 from pigs and 10 from warthogs), and a phylogenetic analysis of ORF2 identified three genotypes (PCV-2b and PCV-2d in pigs and PCV-2c in warthogs). This is the first time that PCV-2 has been identified in warthogs and in Namibia. It is also the first report of PCV-2c in Africa.
