This study reports the frequency and age distribution of porcine hokovirus (PHoV) in domestic pigs and characterizes the strains prevalent in eastern China. A total of 242 tissues from domestic pigs were tested for PHoV using PCR, and six near-full-length genome sequences were used for phylogenetic analysis. The PHoV sequences from domestic pigs in China showed a close relationship to sequences of isolates from Romania and Hong Kong. The results provide evidence that there are differences between PHoV in China compared to early isolates. PHoV infections are more frequent in 0- to 6-week-old pigs than in older ones.
本研究报告了猪呼肠孤病毒（PHoV）在家猪中的频率和年龄分布，并对中国东部流行的毒株进行了特征描述。使用 PCR 对来自 242 份家猪组织的样本进行了 PHoV 检测，并用六个近乎全长的基因组序列进行了系统进化分析。中国家猪中的 PHoV 序列与罗马尼亚和中国香港的分离株序列密切相关。结果表明，与早期分离株相比，中国的 PHoV 存在差异。0-6 周龄猪的 PHoV 感染比年龄较大的猪更为频繁。
