Porcine torovirus (PToV) was detected from intestinal samples of piglets with diarrhea from 20 farms in southwest China. The total prevalence of PToV was 45% (9 out of 20 farms); it was the first detection of PToV in China, and also the study analyzed the phylogenetic relationships between the Chinese PToV and PToV reference strains as well as other representative toroviruses. Genetic and phylogenetic analysis showed the existence of genetic diversity among geographically separated PToV. Statistical analysis of the PToV positive rate as well as a survey for other enteric pathogens in diarrheic pigs suggests that PToV may play a role as a causative agent of severe diarrhea in piglets.
在中国西南部20个猪场的腹泻仔猪肠道样本中检测到猪环曲病毒（PToV）。PToV的总流行率为45%（20个猪场中有9个）；这是中国首次检测到PToV，并且该研究还分析了中国PToV与PToV参考毒株以及其他代表性环曲病毒之间的系统发育关系。遗传和系统发育分析表明，地理隔离的PToV之间存在遗传多样性。对PToV阳性率的统计分析以及对腹泻猪中其他肠道病原体的调查表明，PToV可能是仔猪严重腹泻的病原体。
