title: Prevalence of porcine hokovirus and its co-infection with porcine circovirus 2 in China.
abstract: 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).
