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.
猪圆环病毒 2 型（PCV-2）是引起猪圆环病毒病（PCVD）的病原体。本研究旨在确定 2019 年至 2020 年间在纳米比亚采集的商业猪（n=46）和疣猪（n=42）样本中是否存在 PCV-2。23 份采集样本经 PCR 检测呈阳性（猪 13 份，疣猪 10 份），对 ORF2 的系统发育分析确定了三种基因型（猪中的 PCV-2b 和 PCV-2d 以及疣猪中的 PCV-2c）。这是首次在疣猪和纳米比亚发现 PCV-2。这也是非洲首次报告 PCV-2c。
