Here, we report the frequency of porcine hokovirus (PHoV) infection and its co-infection with porcine circovirus 2 (PCV2) in China. A total of 485 domestic pig samples were tested for both PHoV and PCV2, and NS1 gene sequences from 11 PHoV strains were used for phylogenetic analysis. The prevalence of PHoV and PCV2 was 51.3 % and 36.3 %, respectively, and co-infection occurred in 20.2 %. PHoVs from the Chinese mainland showed a close relationship to those isolated in Hong Kong. Co-infection with both viruses was prevalent, and PHoV may contribute to the induction of postweaning multisystemic wasting syndrome (PMWS).
在这里，我们报告了猪霍奇金病毒（PHoV）在中国的感染频率及其与猪圆环病毒 2 型（PCV2）的混合感染情况。我们共检测了 485 份国内猪样本，检测了 PHoV 和 PCV2 两种病毒，还对 11 株 PHoV 株的 NS1 基因序列进行了系统进化分析。PHoV 和 PCV2 的流行率分别为 51.3%和 36.3%，混合感染率为 20.2%。中国大陆的 PHoV 与香港分离的 PHoV 密切相关。两种病毒的混合感染较为普遍，PHoV 可能会导致断奶后多系统衰竭综合征（PMWS）。
