To survey for porcine kobuvirus infection, a total of 119 pig fecal samples in Korea were collected from three pig farms with good breeding facilities in three provinces. Forty-three (36.1%) of the fecal samples tested were positive for porcine kobuvirus. In addition, porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) infections were not identified in any of the fecal samples, but porcine group A rotavirus (GAR) infection was identified in 11.8% (14/119) of the samples. Nucleotide sequence analysis showed sharp divergence between the five major Korean lineages by the Neighbor-joining method, and each of these lineages had high levels of bootstrap support (99 or 100%). Porcine kobuvirus is widespread in Korea regardless of the clinical condition (diarrhea or non-diarrhea). Piglets under the age of 3 weeks were the main age group infected with porcine kobuvirus, which is the general case for other species of kobuviruses.
为了调查猪杯状病毒感染情况，从韩国三个省份的三个拥有良好养殖设施的猪场收集了总共119份猪粪便样本。检测的粪便样本中有43份（36.1%）猪杯状病毒呈阳性。此外，在任何粪便样本中均未检测到猪流行性腹泻病毒（PEDV）和传染性胃肠炎病毒（TGEV）感染，但在11.8%（14/119）的样本中检测到了猪A组轮状病毒（GAR）感染。核苷酸序列分析通过邻接法显示，韩国的五个主要谱系之间存在明显差异，并且这些谱系中的每一个都有很高的自展支持率（99或100%）。无论临床状况（腹泻或非腹泻）如何，猪杯状病毒在韩国都广泛存在。3周龄以下的仔猪是感染猪杯状病毒的主要年龄组，其他杯状病毒感染其他物种时通常也是这种情况。
