In 2015, a novel equine parvovirus, equine parvovirus-cerebrospinal fluid (EqPV-CSF), was identified from cerebrospinal fluid of a horse with neurological signs and lymphocytosis in USA. In our study, an EqPV-CSF-like virus was detected from 15 serum samples of 65 imported thoroughbred horses during custom quarantine in north Xinjiang province, China. Further field investigation in several major horse-producing areas in Xinjiang using specific PCR showed that this virus was detected mainly in thoroughbred horses (39/154 positive) previously imported, not in local breeds (0/127 positive). Phylogenetic analysis based on NS1 gene showed the virus was grouped together with EqPV-CSF in genus Copiparvovirus. The study presents valuable information showing that EqPV-CSF-like virus was likely exotic and introduced into Xinjiang through international trade of horses.
2015 年，一种新型马细小病毒，即马细小病毒-脑脊液（EqPV-CSF）在美国出现神经症状和淋巴细胞增多的病马的脑脊液中被鉴定出来。在本研究中，从中国新疆北部入境检疫的 65 匹进口纯血马的 15 份血清样本中检测到了一种类似 EqPV-CSF 的病毒。随后在新疆几个主要马产区进行的现场调查使用了特定的 PCR 检测，结果显示该病毒主要存在于之前进口的纯血马（39/154 阳性）中，而不在本地品种（0/127 阳性）中。基于 NS1 基因的系统进化分析表明，该病毒与细小病毒科中的 EqPV-CSF 病毒聚为一组。该研究提供了有价值的信息，表明 EqPV-CSF 样病毒可能是外来的，通过马匹国际贸易传入新疆。
